3 Inch (76mm) Forstner Drill Bit, Tungsten Carbide Tipped Wood Drill Bit, Hex Shank Hinge Cutter for Hard & Soft Wood, Plywood, Plastic（3" (76mm)）

[SPECIAL DESIGN] Using these sharp drill bits, you can drill accurate, smooth, neat holes without burrs, even in end-grain and through knots. Arc curve design head contributes to removing sawdust faster, making your work more efficient. [MATERIAL] The cutting edge is made of K35 monolithic tungsten carbide, hardness ≥91HRA, bending strength >2200N/cm2, resharpenable for a longer service life. It has the advantages of high hardness, wear resistance, good toughness, heat resistance and corrosion resistance. The shank is made of steel 45#. [SPECIFICATIONS] Drilling dia.: 76mm; shank dia.: 10mm; drilling depth: 60mm; total length: 90mm. [APPLICATIONS] Suitable for cutting holes onto solid wood, softwood, hardwood, plywood, MDF, chipboard, and also plastic, rubber, fiberglass. Can be used in drill press, bench drill, vertical drilling machine, CNC carving machine, etc.. [NOTE] 1. Sharp parts contained, please keep away from children and pets. 2. Can NOT be used for metal processing, or the drill bits will get damaged quickly. 3. Material must be fixed during cutting, and the drill bit should be perpendicular to the material. 4. Set slow drilling speed till the drill bit is completely located, then gradually accelerate speed. 5. Water should be injected when processing hardwood, in order to improve drilling accuracy and quality.
