Different Types of Eye Drill & Function

Drill is the most ideal tool for making holes neat and precise. Can be used on wood, plastic or metal. Many types and sizes of holes that can be made using drills, but taking into account the size of the hole and the type of materials we need to use the right drill bit.
Besides even then type material for drill bits also determine the quality of the perforation. metal harder on the drill bit will be much smoother drilling results.
Twist BitsTypes of drill bits are the most widely used and fairly universal function. Can be used using a hand drill or machine drilling machine sits either horizontally or vertically. This could drill to make holes in wood, plastic or metal.Normally available in sizes ∅ 4-12 mm. Better make a central point using nails or screws to the direction of the drill bit when you use a hand drill machine.
Masonry BitsDesigned to make holes in walls, concrete or stone. Used with hammer drilling machine on the setting (vibrate like beer movement beats hammer) and at the end there is a hard metal drill bit as cutting. Usually available in 4-15mm ∅ and eye longer than twist drill bits (300 - 400mm).
Spur BitsKnown as wood drill bit with the tip of the drill bit in the middle and tapered blade slicer on the perimeter. The pointy end in the middle serves to keep the drill straight holes so that the resulting precision and the same ∅.∅ sizes available approximately 6-15mm.
Countersink bitsA bore is angled 90 ° at the ends and work to make the holes 45 ° to the surface of the wood. Usually used when making the hole for the screw head to be flush with the wood surface. This drill can stand alone and some are attached directly to the main drill bit to make the screw holes.
Forster BitIe drill bit that is used to make spoons hinge holes. Are best operated drilling machine sits more stable. Because when using a hand drill machine would be difficult to control the stability of the position of the drill holes and the resulting lack of quality.Diameters are available following the standard diameter hinge spoon, of 15, or 35 mm.
Hole Saw BitsMore precisely we might call saws drill holes for eye shape with a diameter which is like a chainsaw that can be tailored to the needs. Diameter between 25 - 60mm.
