[MATERIAL] The cutting edge is made of monolithic K30 tungsten carbide, with a hardness of ≥90HRA and a flexural strength of >1900N/cm². It is resharpenable for a longer lifespan. It offers the advantages of high hardness, wear resistance, good toughness, heat resistance, and corrosion resistance. The shank is made of 45# steel.

[SPECIFICATIONS] Drilling diameter: 12 mm; shank diameter: 8 mm; drilling depth: 54 mm; Total length: 88 mm.

[APPLICATIONS] Suitable for drilling holes in solid wood, softwood, hardwood, plywood, MDF, particle board, as well as plastic, rubber, and fiberglass. Can be used in a drill press, bench drill, vertical drill, CNC carving machine, etc.

[NOTE] 1. Contains sharp parts; please keep out of reach of children and pets. 2. Cannot be used for metalworking, otherwise the drill bits will be quickly damaged. 3. The material must be secured during cutting, and the drill bit must be perpendicular to the material. 4. Set a slow drilling speed until the drill bit is fully positioned, then gradually increase the speed. 5. Water should be injected when working with hardwood to improve drilling accuracy and quality.
