Feature
●【Parameter】- The drilling diameter of forstner drill bits is 21mm / 0.83-inch, shank diameter is 7mm / 0.28-inch and total length is 80mm / 3.15-inch. Round shank, cemented carbide cutter and high-quality carbon structural steel (45# steel) body.
●【Features】- Tungsten carbide cutting tip with special heat treatment for sharp cutting edge, high hardness, non-burrs and durable use. Arc curve design head for easy chip-removal, more efficient perforation.
●【Advantage】- Small incision resistance to improve the opening speed, chip removal easily. The head adopts arc curve design for easy chip-removal and no tremor. The perforation is neat, smooth, no broken edge. Work noise is small. Easy to install, easy to use, only needs to be installed in the ordinary hand drill that can be used.
●【Applications】- Suitable for bench drill; vertical drilling machine; hand held electric drill; impact drill; CNC carving machine and other drill press. Can be used for drilling holes on wood and plastic products. Wood, plastic, plywood, gypsum board and other materials you need to exquisite perforation.
●【Warm Tips】- Can not be used for cutting metal holes. Before drilling, be sure no nails or other metal objects in wood to avoid causing damage to forstner drill bits. Please note the cutting depth before you purchase.

Description
Auniwaig Forstner Drill Bit, 42-100mm Dia., 80mm Length, Hex Shank, Cemented Carbide Wood Cutter for Woodworking Hole Boring Bit (Blue)
Auniwaig Forstner Drill Bits
- The bit includes a center point which guides it throughout the cut and incidentally spoils the otherwise flat bottom of the hole.
- The cylindrical cutter around the perimeter shears the wood fibers at the edge of the bore, and also helps guide the bit into the material more precisely.
- Made from high quality carbide tungsten steel and being hot-treated,sharp edge,high hardness, accurate positioning,high precision,smooth cutting,impact resistance,high toughness.more smooth,less noise.
- For drilling flat bottom holes with no chippings in any thickness of soft wood. For drilling holes in any direction and making arched openings. For drilling partially overlapped flat bottom holes for easy mortising.
- Suitable for pistol drill, bench drill, vertical drilling machine hand held electric drill, stand motor-driven drilling machine and mobile ribbon type magnetism drilling machine,etc.Perfect used for drilling precision holes in most of different types of wood, such as drawer, mounting spherical door shoot tip, perforation on wood products, and plastic products etc.

Instructions for Woodworking Hole Opener :
- 1. Put the hole opener into the electric drill before use and confirm that it is firmly clamped before it can work.
- 2. Keep the vertical angle with the workpiece when working. After the hole opener drills through the workpiece, the workpiece should be withdrawn while the hole opener is rotating.
- 3. Please clean the sawdust in time to avoid opening failures during continuous work.
- 4. Workers should wear corresponding protective equipment when working to protect them from working safely, and apply rust oil after use to extend the service life.

HOW TO USE
- Processing hardwood or other hard materials should be injected with water to improve the quality and accuracy of drilling, and extend the life of the hole opener.
- The tool edge and tip should be sharpened in time if they are worn or damaged, or the tool will be damaged quickly. Can not drill metal and non-ferrous metal, otherwise the hole opener will be damaged quickly.
- The cutting material must be fixed, and the drill bit should be perpendicular to the material. It will damage the tool or the material if the cutting material moves during the drilling process.
WIDE APPLICATIONS
Application:
- Suitable for cutting holes onto most low hardness wood and wood products. Can easily enlarge existing holes and bore any arc of a circle. Drills flat bottom holes, pocket holes, and overlapping holes.
- Great for boring concealed hinges and door locks. The cemented carbide tip is designed to cut through hole cleanly. Can be used for wood products perforation, mounted spherical door shoot tip, drawer, plastic and wood products, plywood, etc..
- Suitable for bench drill, vertical drilling machine, CNC carving machine, etc. The bit in the positioning is required to very low speed, and then gradually accelerate after complete position. Add water for lubrication and temperature reduction when drilling.
- NOTE: This forstner drill bits is widely used on desktop (fixed) equipment, and can NOT be used on handheld power tools (such as hand drill or electric drill). Can not drill metal and non-ferrous metal. To avoid causing damage, be sure no nails or other metal objects in wood before drilling. The cutting edge and tip of the opener should be sharpened in time.
