Machine Taps HexDrive, Form C 15° RSP, HSS-E, M 3-12

Applications:

• Thread cutting M3–M12 in steels up to 900 N/mm²
• For unalloyed and low-alloy steels
• Perfect for blind holes – Form C 15° RSP
• Usable in pillar drills, machine tools, and suitable cordless tools
• Ideal for workshops, maintenance, assembly, and small series

Advantages:

• HSS-E material for long tool life
• 15° RSP spiral flute ensures reliable chip evacuation in blind holes
• HexDrive shank for secure positioning and torque transmission
• Complete size range from M3 to M12
• Consistent, precise threading performance

1. Drill the core hole: Follow the core hole diameter chart; ensure additional depth for the thread bottom.
2. Chamfer the entrance: Slightly countersink the hole for easier tap alignment.
3. Clamp the tool: Secure the HexDrive tap in the toolholder, quick-change holder, or chuck.
4. Tap the thread: Use correct speed and feed; apply cutting oil for optimal results.
5. Monitor chip flow: Ensure chips are evacuated properly through the spiral flute.
6. Reverse cleanly: Retract the tap smoothly from the blind hole.
7. Inspect: Check the final thread with a matching screw or thread gauge.

What is Form C 15° RSP best suited for?
It is optimized for blind holes. The 15° spiral flute ensures upward chip evacuation and reduces chip packing.

Can I use these taps for through holes?
Possible, but Form B taps are generally more efficient for through-hole applications.

Which materials are suitable?
Free-cutting, unalloyed and low-alloy steels up to 900 N/mm².

Should I use cutting oil?
Yes. Cutting oil or coolant significantly improves tool life and thread quality.

Can I use these taps in a cordless drill?
Yes, with proper speed control and a precise toolholder. For series production, a machine tool is recommended.
