Types Drill Bits You Can Choose From
Many a time when you are stuck during drilling a hole, you need a specific bit to get the job done. Let's understand the types of drill bits designed for specific purposes.
Adjustable bit: comes with an adjustable cutter to bore holes of varying sizes. Used for drilling holes for piping or wiring where a rough cut is acceptable.
Around-the-corner bit: to cut curved holes in tight corners with an angled cutting surface.
Auger Bits: designed to drill holes in wooden material. The drilling end has a ***** head so that the bit can self feed.
Brad-point drills: similar to standard bits but have a sharpened point that makes it easier to start in wood. Drills cleaner holes than a spade bit.
Counterbore: a drill bit which permits a ***** to be driven beneath the woods surface. The hole can then be filled with a plug.
Countersink bit: has an angled tip that's designed to form a depression for ***** heads.
Drill Saw bit: Used to cut holes in metal and wood. Can enlarge existing holes.
Expansion bit: another term for adjustable bit. An expansion bit uses an adjustable cutter to bore holes of varying sizes.
Fly Cutter: used on a drill press to cut circles. The diameter of the circles can be adjusted by changing the cutter setting.
Forstner Bit: used to a create a flat bottomed hole in wood, a mortise can be formed by cutting overlapping holes. Also used to a create a segment of a hole at the edge of a board. Use only in a drill press.
Glass bit: has a carbide tip for drilling through glass.
Hole saws: cuts holes from 1" to 6" in diameter, have a center bit for guiding the cutting edge of the saw.
Masonry bits: have carbide tips for drilling holes in masonry, use at speeds below 400rpm.
MultiSpur bit: drills holes large enough to run pipe or conduit through. A threaded ***** in the center of the cutting circle pulls the work towards the cutting edge.
Nail Spinner: used to start finishing nails, prevents wood from splintering as it is driven in. A hammer is used to finish the job.
Reamer Bit: a tapered bit that can be used to fit into an existing hole either to enlarge it.
Rotary Files: used for the same purpose as a conventional file, great for expanding holes in metal and cleaning up rough edges.
Paint Mixers: consist of a shaft with fan type blades. Put the shaft into the paint before rotating to avoid splatter.
Plastic Bit: has a tip that prevents splintering when drilling in plastic. Drill slowly and reduce pressure as you reach the other side of you work.
Plug Cutter: can be used to cut out cylindrical shapes from wood. These small cylindrical plugs are used to cover ***** heads. This bit should only be used in drill press.
Screw driving bits: used for driving screws.
Screw Pilot bit: used to drill a pilot hole, body hole and countersink all at the same time.
Spade bit: has a sharpened point and used for drilling large diameter holes in wood. These bits work best at fast drilling speeds, but remember to start slowly.
Step Bit: a tapered bit with up to 13 diameters as the bit penetrates the work it drills a hole with an increasingly large diameter.
Twist drills: standard drill bits, used for drilling small diameter holes in wood and metal.
Wire Brushes: used to clean up metal, remove rust. Available as either a cup or a wheel with wire brush on the rim.
Woodscrew bit: available in a variety of sizes to match particular ***** sizes. Woodscrews are used to drill a pilot hole, body hole and countersink all at the same time.

I did experience a couple of catches, but I attribute that to my over agressiveness and lack of sufficient knowledge of this tool on carbide round. I am in a position to see other applications for this toolOver time cutting tools will dull and it is oftentimes] easier to have a part tool abrasive that you may take right to the cutter, The application of a fine diamond file can radically change the top of the pallet for a more effective movement.
