Drill | Solid carbide Step Drill | Accusharp Cutting Tools

Drill or drill machining tools used for making round holes in solid material. Drilling tools are End cutting tools designed for producing holes in the work piece. The diversity of drills can be used to cut circular holes in work pieces. Step drill preferably suited for cutting metals, Plastic, Wood.

ACCUSHARP offers a complete range of high performance, general-purpose, finishing, roughing, high-speed, micro, and material-specific S/C Step drill for high productivity and extended tool life. HSN2 coating for the higher life, SC drill that offers a one-pass solution in steels and irons in traditional tap sizes to reduce cycle time and increase productivity. Drilling and chamfering in one shot. The highly polished surface ensures superior chip evacuation even when a low-pressure coolant is applied.

For General Purpose usually HRc30 ~ HRc50

Special design for good centring, smooth chip removal and powerful drilling

Special surface treatment after coating to reduce friction and better chip flow

With the help of experienced engineers, we have been able to design and develop Solid Carbide Step Drill. These are designed and manufactured by the professionals in compliance with the industry standards. The offered drills are widely acknowledged for their attributes such as perfect finish, accurate dimensions, high strength and durability.
