## Summary description

Solid carbide (VHM) drill bit MasterDrill DIN 6537 with diameter 5.10 mm, overall/working lengths 66/28 mm and 3xD length ratio. HA6 coating enhances wear resistance for machining hardened steels and general metalworking. Designed for high-speed drilling with precise centering and long tool life in industrial and workshop applications.

## Long description

Solid carbide drill bit MasterDrill manufactured to DIN 6537 with a diameter of 5.10 mm, overall length 66 mm and working length 28 mm (3xD). The VHM construction and HA6 surface coating provide increased wear resistance and thermal stability for high-speed drilling of hardened steels and general metalworking. The geometry is optimised for precise centring, stable chip evacuation and consistent hole quality in industrial and workshop applications.
Advantages
The carbide body ensures rigidity and minimal deflection during drilling, while the HA6 coating reduces abrasive wear and extends tool life. The 3xD length ratio balances reach and stiffness for controlled drilling depths. Ground flutes and point geometry improve centring accuracy and reduce thrust, enabling faster cycle times and repeatable hole diameters.
Suitable for
High-speed drilling in hardened and alloyed steels
General-purpose metalworking in production and toolrooms
Precision drilling where tight diameter tolerances are required
Short- to medium-depth holes up to three times the diameter
When it may not be suitable
This solid carbide 3xD drill is not intended for deep-hole drilling beyond the specified 3xD range; for deeper holes, specialized long-reach or gun drills are more appropriate. It may not be the best choice for extremely interrupted cuts or highly abrasive cast materials unless machining parameters are adjusted and coolant is applied.
Key specifications
Material: solid carbide (VHM)
Diameter: 5.10 mm
Overall length: 66 mm
Working length: 28 mm (3xD)
Coating: HA6 surface treatment
Standard: DIN 6537
How to use
Secure the drill in a suitable collet or drill chuck with adequate runout control. Use appropriate cutting speeds and feeds for carbide tooling and the workpiece material; apply coolant or cutting fluid when machining steels to control temperature and improve chip evacuation. Start with conservative feed rates and increase gradually while monitoring hole quality. Retract periodically on long runs to clear chips and maintain coolant flow to the cutting edge.
What to consider before purchase
Confirm compatibility of diameter and working length with required hole depth and machine spindle
Check machine speed and feed capability for carbide tooling
Consider workpiece material and whether HA6 coating matches the intended application
Usage recommendations
Use steady spindle speeds and consistent feed; prefer through-coolant or external flood coolant for steel machining, and replace the drill at the first signs of excessive wear to maintain hole accuracy. For best life, avoid heavy pecking cycles with high impact and inspect tool runout regularly.
