Frequently Asked Questions

What is the WALTER 33/64" screw machine drill bit used for?

This WALTER cobalt drill bit is designed for chip-clearing in screw-machine applications. Its 130° point, parabolic flute, and fast spiral geometry efficiently evacuate chips in deep-hole drilling on CNC lathes and automatic screw machines, reducing cycle time in production environments.

What are the specifications of the WALTER A1148-33/64IN drill bit?

The WALTER A1148-33/64IN is a 33/64" (0.5156 inch) diameter cobalt screw-machine length drill bit with a 130° point, parabolic flute, and fast spiral design. It is made from cobalt steel for heat resistance and durability in high-speed machining of tough materials.

Where to buy WALTER drill bits worldwide?

How to select the right screw machine drill bit for my application?

For screw machine applications, match the drill diameter (e.g., 33/64") to your hole size. Choose cobalt for heat resistance in stainless or hardened steels. The 130° point reduces thrust on thin workpieces, while parabolic flutes improve chip evacuation in deep holes. Consult WALTER's technical data for feed and speed recommendations.
