21mm Forstner Drill Bit, Tungsten Carbide 21mm Forstner Bit with Round Shank for Wood Plastic Hole Drilling, Suitable for CNC, Electric Drill Machines &More
Sharper & Quicker Drilling - The 12mm forstner drill bit is made of premium tungsten carbide material and welded by high frequency technology, which makes it stay sharp and high hardness, drilling holes in significantly less time than traditional forstner drill bits.
Accurate & Smooth Cutting - The 12mm (15/32 inch) forstner bit has two spurs and one center point that can accurately locates the center of the hole and offers high concentricity and equal pressure when drilling, achieving a more efficient perforation. The smooth cutter edge also provides smooth cuts without burrs, reducing the chances of chipping the wood.
Easy To Use - The round shank design makes the 12mm forstner bit is easy to install, suitable for drill press, bench drill, vertical drilling machine and CNC carving machine. 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 drilling hole opener.
Applications - The carbide forstner drill bits are only suitable for processing wood or soft non-metallic materials, such as wood products perforation, mounted spherical door shoot tip, drawer, plastic and wood products, plywood, etc. Before drilling, the cutting material must be fixed and the drill bit should be perpendicular to the fixed material.
