Machine Taps HexDrive, Form B, HSS-E, M 3-12

Applications:

• Thread cutting M3–M12 in steels up to 900 N/mm²
• For free-cutting, unalloyed and low-alloy steels
• Optimised for through holes (Form B)
• Suitable for pillar drills, machine tapping, cordless tools
• Maintenance, workshop, assembly and small series production

Advantages:

• HSS-E for high tool life and stable cutting performance
• HexDrive allows safe, slip-free torque transfer
• Complete size range M3–M12
• Reliable chip evacuation through Form B geometry
• Consistent thread quality when used correctly

1. Drill core hole: Use the correct core hole diameter; ensure full through drilling.
2. Chamfer: Lightly chamfer the hole to ease tap insertion.
3. Clamp tool: Secure the tap in the machine holder, quick-change holder or chuck.
4. Thread cutting: Use proper cutting speed and lubricant (cutting oil recommended).
5. Reverse: Retract the tap smoothly, allowing chips to exit the through hole.
6. Check thread: Verify with a suitable screw or gauge.

Which materials are suitable?
Free-cutting and low-alloy steels up to 900 N/mm². For stainless steel, use dedicated high-performance taps.

Can I use these taps in a cordless drill?
Yes, as long as speed control and stability are ensured.

Are these taps suitable for blind holes?
No—Form B geometry is intended for through holes.

Is cutting oil recommended?
Yes, to increase tool life and thread quality.

Can these taps cut stainless steel?
Only limited suitability. For austenitic stainless steels, use specialised taps.
