2. Hack Saw • Used to cut metal

3. Twistbit- • Designed to drill holes in wood and metal. • If you use it to drill metal, make sure to lubricate it with machine oil and cut with slower speed.

4. Slip-joint pliers • Increases the grip upon a object • The jaw size can be expanded by slipping the pivot into different positions.

5. C-clamp • Good for small jobs and when holding objects in a localized area.

6. File Card • Cleans debris from files and rasps.

7. Block Plane • Used to smooth the surface of small pieces of wood.

8. Hand-screwclamp • Clamps without marring. • Perfect for odd-shaped assemblies; will even clamp round objects. • Each jaw works independently, allowing the jaws to angle toward or away from each other.

9. Mallet • Used to hammer without marring. • The head is typically made of rubber or rawhide (leather).

10. Hand saw • Used to cut straight lines in wood stock. • A crosscut saw cuts across the grain of wood. • A rip saw cuts with the grain of wood. • Stock is material in its native form.

11. Sliding T-bevel • Used for checking and transferring angles. • The blade pivots and can be locked to match any angle.

12. File & Rasp • Files are used to smooth the edge of wood or metal. • A rasp shapes wood rapidly by removing larger amounts of material.

13. Claw hammer • The most commonly used hammer. • Curved claw provides leverage for pulling nails. The face may be flat, bell-shaped, or checkered. • For most work, a 13 or 16-ounce head weight is appropriate.

14. Straight & Phillips head screwdriver • Screwdrivers come in many different lengths, widths, and colors. • The straight screwdriver is used to insert or remove slotted fasteners. • The Phillips head screwdriver is used to insert or remove Phillips head fasteners.

15. Wood Chisel • Used to cut grooves and/or slots in wood.

16. Combination square • Used to check and layout 90° and 45° angles • The handle slides on the blade so that it can be used as a depth gauge to mark equal distances. • A spirit level in the handle can be used to check level and plumb.

17. Carpenter's level • Used to check level and plumb. Digital models are also available. • Standard lengths are 24" and 48".

18. Auger Bit • Special bit used to drill holes in wood. • It has a tang and is only used in a brace. • This pyramid shaped end is called the tang.

19. Try square • The most common woodworking square for laying out and checking 90° angles. • It can be used to test a surface for levelness and squareness. • Used most often to make lines across the face or edge of stock.

20. Long-nose or needle-nose pliers • Used to hold a small object, especially in electrical work. • Sometimes they have a wire cutter on the side for cutting small-gauge wire.

21. Nailset- • Conceals the heads of finishing nails by driving them below the surface of the wood.

22. Center Punch • Used to indent the surface of wood or metal to help a drill bit start drilling at the proper place.

23. Coping Saw • Used to cut curves or irregular lines in wood.

24. Calipers • For very accurate measurements or layouts. • Calipers are available for outside and inside measurements. Outside Caliber Inside Caliber

25. Brace • Bores larger holes in wood by hand. • Special bits that have a “tang” on their end must be used in the brace.

26. Spadebit- • Drills holes in wood only. • The long point makes it easy to locate the hole. • Feed the drill at a slow speed as it enters the wood. • If you don’t use scrap wood as a backer board, it will leave a splintered exit hole.

27. Scratch awl • Used instead of a pencil to make fine layout lines, especially on metal. • It can also be used to make small holes for starting drill bits, nails, or screws in wood.

28. Backsaw • A fine-tooth crosscut saw with a heavy metal band across the back to strengthen and stiffen the blade. • It is used to make fine cuts and is often used in a miter box.

29. Bar Clamp • Used to clamp wood edge to edge when gluing stock together.

30. Surform Tool • Used to shape wood.

31. Spoke Shave • Used to shape wood with rounded surfaces.

32. Carpenters Square • Used to frame houses and layout roof rafters.
