material holding the nail is braced securely before you pull.

–When using prying tools, be sure to keep balanced footing and a firm grip on the tool.

• Ripping Bars–Wrecking Bars• Used for heavy-duty dismantling of wood-work , such

as tearing apart building frames or concrete forms.


• Nail Pullers– Cat’s Paw• Straight steel rod with a curved claw at one end.• Used to pull nails that have been driven flush with the

surface or slightly below it.

– Chisel Bars• Has a claw at each end and is ground to a chisel-like

bevel on both ends.• Used like a claw hammer to pull nails.

– Flat Bars• Has a nail slot at the end to pull nails out from tightly

closed areas.• Can be used as a nail puller or as a small pry bar.

Agenda:1. QOD & Measurement2. Hand Tools PowerPoint3. Activity – Types of Chisels4. Activity – Types of Pliers5. Review


Chisels and Punches

• Chisels have a sharpened, beveled edge and are used to cut and shape wood, stone, or metal. –There are two types: wood chisels and cold

chisels• Punches are used to indent metal, drive pins,

and align holes.• When working with punches and chisels, wear

safety goggles, and do not use a chisel head or hammer that has become mushroomed or flattened.

Chisels and Punches

• Wood Chisel– One common use for a wood chisel is to make a

recess for a door hinge.– A mallet is used to strike a wood chisel.–Wood chisels are sharp and must be handled

carefully.

• Cold Chisel– Used to cut off rivets, nuts, and bolts.– A holding tool should be used to hold the chisel

in place when striking it.

Screwdrivers

• Screwdrivers– Used to tighten or remove screws from material–Most common• Slotted• Phillips

• Do not use a screwdriver near live wires or as an electrical tester.

Screwdrivers

• Types

Screwdrivers

Screwdrivers

• A screwdriver has three distinct parts: – handle– shank– blade, most blades are made of tempered steel

Pliers and Wire Cutters

• Pliers can be thought of as a type of wrench.– use pliers to hold, cut, and bend wire and soft

metals.

• Pliers should not be used on nuts and bolts, as pliers are likely to round the edges of the six-sided head, so that wrenches will no longer fit properly.

• High-quality pliers are made of hardened steel.


• Slip-Joint (Combination) Pliers– Used to hold and bend wire and to grip and hold

objects during assembly operations.

• Long-Nose (Needle-Nose) Pliers– Used to get into tight places where other pliers

will not reach or to grip parts that are too small to hold with your fingers.

• Lineman Pliers (Side Cutters)– Used to cut heavy or large gauge wire and to hold

work.


• Tongue-and-Groove Pliers– Have serrated teeth that are used to grip flat,

square, round, or hexagonal shapes.

• Locking Pliers– Used to grip firmly onto objects the way a vise

does.

Agenda:1. QOD & Measurement2. Hand Tools PowerPoint3. Activity – Types and Uses of Wrenches4. Review


Wrenches

• Non-adjustable wrenches– Open-end wrench

• has an opening at each end

– Box-end wrench• have six or twelve points• they are easier to use because they provide a firmer grip

and will not slip off the nut or bolt

– Hex Key (Allen) wrench• made to fit the socket of a hex head screw or bolt• they are often used to tighten setscrews

– Combination wrench• have an open end on one end and a box end on the other

Wrenches

• Nonadjustable wrenches

Wrenches

• Striking wrench– striking or slugging wrenches are made to be hit

with a mallet or hammer. – they are often used to loosen nuts and bolts that

are stuck because of rust or corrosion. – pull it toward you rather than pushing it away

from you.

Wrenches

• Striking wrenches

Wrenches

• Adjustable wrenches– Pipe wrench & Spud Wrench• Pipe wrenches, also called monkey wrenches, are used

to hold and turn threaded pipe. • The jaw is spring-loaded, so the wrench can be

repositioned without readjusting the jaw.

– Adjustable-end wrench• When using an adjustable wrench, adjust the jaws so

they fit the head tightly and turn the wrench so you are putting pressure on the fixed jaw.

Wrenches

• Adjustable wrenches

Sockets and Ratchets

• Socket wrench sets include different combinations of sockets and ratchets that are used to turn the sockets.– Sockets = part that grips the nut or bolt– Ratchet = handles

• Sockets come in different lengths.– The longer socket is called a deep socket because

it is used when normal sockets will not reach down over the end of the bolt to grip the nut.

Sockets and Ratchets

Torque Wrenches

• Torque wrench measures resistance to turning. Only used when a torque setting is specified for a particular bolt or nut.– Specifications stated in inch-pound or foot-

pounds.

• When using a torque wrench hold the head of the torque wrench with one hand to support the bolt and to make sure it is properly aligned.

Agenda:1. QOD & Measurement2. Hand Tools - PP3. Activity – Types & Uses of Squares4. Review


Rules and Other Measuring Tools

• Steel Rule– Usually 6 or 12 inches long, but longer sizes are available

• Measuring Tape– Marked with the ½-inch, ¼-inch, 1/8-inch, and 1/16-inch markings

– The concave (or curve) of a tape measure blade is designed to strengthen the blade and makes the tape easier to read when it is placed on a surface that needs to be marked

• Wooden Folding Rule– Usually calibrated in 16ths of an inch.– It is better than a cloth or steel rule at measuring vertical

distances because of it stiffness.

• Laser Measuring Tool– Can be considered a battery-powered, electronic version of a

tape measure.

Rules and Other Measuring Tools

Levels

• Levels – used to determine how level a horizontal surface is and how plumb a vertical surface is.– Spirit Levels• have three vials filled with alcohol to check for level

and plumb.• 2’ & 4’ Level• Torpedo Level

– Laser Level – a single worker can accurately and quickly establish plumb, level or square measurements.

Levels

• The spirit level has three vials filled with alcohol. The position of the air bubble in the vial indicates the degree of level or plumb.

• If the air bubble is centered between the lines on the vial, the surface is level or plumb.

• Keep in mind that the vials are fragile. If you abuse or drop your level, you may damage or dislodge the vials.

Levels

Levels

• Laser levels are used to level foundations, establish slopes, square framing, and for a variety of other purposes.

Squares

• Carpenter's Square– Is the shape of an “L” and used to square up wall studs and sole

plates. – Used mainly to square up sections of work such as wall studs or

sole plates.– It has a 24” blade and a 16” tongue, forming a right (90°) angle.– One side contains tables for calculating the lengths of rafters, as

well useful formulas and other data

• Rafter Angle Square, or Speed Square– Marked with degree gradation for fast and easy layout forming

a right (90°) angle.– Specifically designed for laying out roofs and stairs– It is a combination tool consisting of a try square and framing

square.

Squares

• Try Square– Used mainly for woodworking to check lumber to

see if it is warped or bowed– Check square of a cut or adjoining surface– Is a fixed 90° angle used to lay out cutting lines

• Combination Square– Used for making 90 and 45 degree cuts, check

level and plumb surface.– Has a moving head that can be slid along the blade– Can be use as a straightedge, or to mark 45 and 90°

angles.

Agenda:1. QOD & Measurement2. Hand Tools - PP3. Activity – Types & Uses of Saws4. Review


Plumb Bob

• Plumb Bob– A pointed weight attached to a string and it uses

the force of gravity to make the line hang vertical, or plumb.

– Some chalk lines are made to double as plumb bobs.

– Used to make sure a wall or door jamb is vertical, or plumb. Or to place a post under a beam.

Plumb Bob

Plumb Bob

Chalk Lines

• Chalk Line– A piece of string or cord that is coated with chalk

used to mark a straight line.–Mechanical chalk lines like the ones shown are

filled with chalk and automatically chalk the line for each use.

– Some mechanical chalk lines are pointed, so they can double as a plumb bob.

Chalk Lines

• To use, stretch the line tightly between to points and then snap it to release a chalky line to the surface.

Utility Knives

• Utility Knife– Retractable blade are the safest.– Always place something under the object you are

cutting to protect the surface material.– Used for cutting the following material:• Roofing felt and asphalt roofing• Vinyl or linoleum floors• Fiber board• Gypsum board• Insulation• Cardboard

Utility Knives

Saws

• Backsaw– Used for cutting joints, especially miter joints and

tenons.

• Compass, or Keyhole, saw– Can fit into tight places.– Used to cut curves quickly in wood, plywood, or wall

board.

• Coping saw– U-shaped frame so it can cut at angles. – Has a very narrow, flexible blade– Used to cut irregular shaped molding and make it fit

together.

Saws

• Drywall saw– It is long and narrow and it is used to cut softer

building material, such as drywall.

• Hacksaw– Used to cut through metal such as nails, bolts and

pipes.– The teeth of a hacksaw blade must face away

from the handle.– Designed to cut on the push stroke and not on the

pull stroke.

Saws

• Handsaw - used for cutting wood– Crosscut Saw• Used to cut across the grain, the direction of the

fibers, of the wood.

– Ripsaw• Used to cut with the grain, parallel to the wood fibers,

of the wood

• Saw Safety and Maintenance:– Brace yourself on the last stroke when sawing so

you are not thrown off balance on the last stroke.– Don’t let the saw teeth come in contact with

stone, concrete, or metal.

Agenda:1. QOD & Measurement2. Hand Tools – PP3. Activity – Types & Uses of Clamps4. Review


Files and Rasps

• Files– Used to cut, smooth, or shape metal parts and to

sharpen many tools– Have slanting rows of teeth– Classified by the cut of their teeth

• Rasps– Have individual teeth– Classified by the size of their teeth

Files and Rasps

Files and Rasps

• File Card– After you have used a file, brush the filing from

between the teeth with a file card, pushing in the same direction as the line of the teeth

Clamps

• C-clamp– Used to hold material between the metal jaw of

the frame and the shoe.

• Locking C-clamp– A knob in the handle controls the width and

tension of the jaws, works like locking pliers.

• Spring clamp– Simply squeeze the handles of the clamp and

insert the jaws onto the desired material.

Clamps

• Bar clamp– It has a fixed jaw at one end and a sliding jaw

with a spring locking device that moves along the bar.

• Quick Grip bar clamp– Specifically designed to allow you to squeeze up

to 600 pounds of force with one hand.

• Pipe clamp–Much like a bar clamp, but with a pipe instead of

a bar.

Clamps

• Hand-screw Clamp– Can spread pressure over a wider area than most

clamps and each jaw works independently.

• Web clamp– Uses a band to apply even pressure around a

piece of material.

• Always discard clamps with bent frames.

Clamps

Clamps

Clamps

• When clamping wood or other soft material:– You should use pads or thin blocks of wood

between the clamp and the work.– Do not apply excessive pressure to a clamp.– Clamps with bent frames must be discarded.

Chain Falls and Come-Alongs

• Chain Fall– Used to safely move heavy loads.– It is a chain-and-tackle device used to hoist loads. – A chain fall has an automatic brake that holds the

load after it has been lifted. The brake holds the load until the lowering chain is pulled.

–Manual chain falls are operated by hand, but some have electric drive motors that are operated from an electrical control box.

– Some lubrication of a chain fall or come-along may be required. If so, be very careful not to get any lubricant on the clutches.



• Come-Along– Used to drag loads and never to lift objects. It does not

have the necessary safety features.– Come- alongs, also called cable pullers, use a ratcheting

handle to move heavy loads horizontally over short distances. They can support up to 6 tons.

– One end of the come-along is secured to a stationary object; the other end is connected to the object to be moved.

– Once the connections are made, the ratchet handle is used to take up the chain or cable and move the object.

– Some lubrication of a chain fall or come-along may be required. If so, be very careful not to get any lubricant on the clutches.


Shovels and Picks

• Shovels– Round – used to dig holes or remove large amounts of

soil.– Square – Used to move gravel or clean up construction

debris.– Spade – used to move large amounts of soil or dig

trenches that need smooth, straight edges.

• Picks– Used to break hard or rocky soil, to level out stones and

pavers, to chop tree roots, etc.– Be sure that the head of the pick is fixed firmly to the

handle.
