## Summary description

Solid carbide (VHM) Walther drill bit with 8.50 mm diameter, 61 mm working length and 103 mm overall length. Designed to DIN 6537 with 5xD length ratio and HA10 geometry for reliable chip evacuation and long tool life. Suitable for drilling steels and general metalworking on drilling machines and CNC equipment.

## Long description

Walther carbide drill bit Ø8.50 mm, overall 103 mm, working 61 mm, 5xD, HA10 VHM, DIN 6537 is a solid carbide (VHM) twist drill engineered for precise holemaking in steels and general metalworking. The tool features an 8.50 mm diameter, 61 mm effective cutting length and a 103 mm overall length. Manufactured to DIN 6537 with a 5xD length ratio and HA10 geometry, this Walther drill is designed to provide reliable chip evacuation, consistent concentricity and extended tool life on drilling machines and CNC equipment.
Advantages
The solid carbide construction ensures high rigidity and wear resistance, reducing chatter and maintaining dimensional accuracy over long production runs. HA10 geometry optimises cutting conditions for steels and common alloys, promoting efficient chip formation and evacuation. The 5xD length ratio balances reach and stiffness, allowing access to moderately deep holes while preserving stability. Compatibility with standard tool holders and machine spindles makes it suitable for both manual drilling machines and CNC machining centres.
Suitable for
 Drilling through unalloyed and low- to medium-alloy steels
 General metalworking tasks on drilling machines
 CNC machining operations requiring consistent hole quality
 Production runs where tool life and repeatability are important
Key specifications

How to use
Secure the Walther carbide drill bit in an appropriate collet or chuck that matches the shank and the machine's spindle. Select cutting speeds and feed rates suitable for an 8.50 mm solid carbide tool and the specific grade of steel being machined, using coolant or cutting fluid as recommended for improved chip evacuation and tool life. Start with a pilot or centre drill if required by the application, and apply steady axial feed without excessive pecking unless machining deep or interrupted holes. Inspect hole quality and tool wear periodically and replace the drill when cutting performance or dimensional accuracy degrades.
Usage recommendations
For best results on steels, use coolant and moderate cutting speeds to limit heat at the cutting edge; maintain stable workholding and minimal runout to preserve tool life and hole accuracy. For production settings, monitor wear and consider tool regrinding or replacement to ensure consistent performance.
