  1. Tool Identificationand Use

  2. Where do you buy tools? Dealers • Snap-On • Mac Retail Stores • Canadian Tire • Wal-Mart

  3. Tool Material What makes a quality tool? • Made of high-strength alloy steel • Light and easy to use • Highly polished • Easy to clean • Comfortable to handle

  4. Handling and Storage Where and how should you store tools? • Keep tools stored in a roll-type tool cabinet • Remove oil and dirt from tools • Dirt can damage moving parts of tools • Lightly oil clean tools to prevent rust

  5. Hammers Ball Peen • Used for general striking work • One rounded striking face • One flat striking face • Available in a range of sizes from a few ounces to several pounds

  6. Hammers Sledge Hammer • Large flat head • Made of metal • Able to distribute force over a wide area

  7. Hammers Brass Hammer • Used to prevent marring the work surface being struck • Head made out of brass

  8. Hammers Plastic Tip Hammer • Used to prevent marring the work surface being struck • Similar to brass hammer, but plastic is an even softer material

  9. Hammers Rubber Mallet • Usually made of solid rubber • Some Rubber Mallets have an internal cavity in the head filled with lead shot • These are called “Dead Blow Mallets” and prevent rebound when striking

  10. Chisels • Come in a variety of sizes and types • Used for cutting bolts and rivets • Can be held in hand or secured with a holder

  11. Chisels Using a chisel holder protects your hands when striking with a hammer Chisel Holder

  12. Punches Starting Punch • Has a tapper that ends with a flat tip • Used for driving out rivets after the heads have been cut off

  13. Punches Drift Punch • Has the same diameter for the majority of its length • Used for driving out rivets after the starting punch

  14. Punches Aligning Punch • Has a long gradual taper and a finer point than the starting punch • Used to align corresponding holes • Punch is pushed through the holes and then pulled upright to align them

  15. Punches Center Punch • Used to mark materials before drilling or marking parts • When used for drilling, a small impression is made in the material to align the drill bit

  16. Files Common File Types • Flat Mill • Half-Round • Round • Square • Triangular All file types come in different sizes and with cutting edges that range from coarse to fine.

  17. Files File Cut • Rough to Smooth depends on the number and size of cutting edges

  18. Files • Files should have a handle firmly attached to the tang • This allows a firm grip and prevents the tang from piercing the hand

  19. Files Rotary Files • Come in a selection of shapes and sizes • Designed to be used in a hand drill or hand held air grinder

  20. Drills Power Drills • Operated by compressed air or electric motors • Either type of power drill uses a chuck to secure drill bits • 3/8” and ½” are the most common sizes • This size means the largest drill bit size the chuck can fit

  21. Drills Cordless Drills • Able to fit into tight spots a power cord or air hose cannot • With the use of adapters they can be used as screw and nut drivers • Useful for quickly removing component screws and bolts

  22. Drills Drill Press • Drill motor and chuck are mounted on a stand • Material to be drilled is mounted directly below on table • Drill bit is lowered into work by turning hand lever • Eliminates the need to hold drill and ensures proper alignment

  23. Drills Drill Press • Can only be used on parts that will fit on the mounting table • CANNOT be taken to the vehicle for drilling on a part that cannot be removed

  24. Drills Drill Bits • “Chucked” in a drill’s chuck • Does the actual cutting when drilling holes • Available in fractional inch sizes (standard) or metric • Usually made of either carbon steel, high-speed steel, and cobalt steel alloys

  25. Reamers • Used to enlarge or shape holes • Makes the hole more accurate in size and smoother • NOT be used to make deep metal cuts • Should only cut a few thousandths of an inch at a time

  26. Reamers • Some reamers are a fixed size, some are adjustable • Tapered reamers are good for removing burrs and for starting taps
