VÖLKEL GREEN RING HSSE Tap Set M3–M12 DIN 371/376 (incl. drills)

VÖLKEL GREEN RING Machine taps for blind holes (set of 14 pcs.) incl. drills DIN 371/376 M 3 – M 12

The VÖLKEL GREEN RING machine tap set in HSSE is your reliable all-in-one solution for production and maintenance. The GREEN RING spiral-flute geometry enables secure chip evacuation—ideal for blind holes and long-chipping materials. The set covers metric ISO coarse threads M3–M12 and includes matched twist drills for core holes.

Application & Benefits

For general use in metalworking—especially when you need repeatable tapping in blind holes and expect long, continuous chips.

  • For non-abrasive materials up to 900 N/mm²
  • Unalloyed & low-alloy steels, long-chipping materials
  • HSSE for heat-resistant cutting edges and long tool life
  • Spiral flute for controlled chip evacuation from blind holes
  • ISO 2 (6H) – consistent ISO-fit threads per DIN 13

  • Twist drills: 2.5 / 3.3 / 4.2 / 5.0 / 6.8 / 8.5 / 10.2 mm

From core hole to finished thread, everything you need is in one box—covering the sizes you use daily in service, assembly, and repair.

Step-by-Step (Machine tapping)

  1. Drill the core hole: Pick the matching twist drill (e.g., M8 → Ø 6.8 mm). Drill, deburr, and lightly countersink.
  2. Clamp & align: Secure the tap coaxially (length-compensation chuck recommended). Rigidly clamp the workpiece.
  3. Lubricate: Apply cutting oil/gel to tool and bore—especially important in blind holes.
  4. Tap the thread: Use appropriate speed/feed. The spiral flute conveys chips upward out of the blind hole.
  5. Retract: Back the tool out in a controlled manner. Avoid lateral loading.
  6. Clean & verify: Remove chips, visually inspect, and verify with screw/gauge (6H).
  7. Document (optional): Note parameters and tool life for repeat jobs.

FAQ

Can I combine VÖLKEL drills and cutting oils with this set?
Absolutely. The matched drills are included; using cutting oil/gel further improves surface finish and tool life.

How do I determine the right cutting speed?
It depends on the material. Start with conservative parameters, observe chip form and finish, then optimize.

Is the set suitable for use on CNC machines?
Yes—use appropriate holders (e.g., tapping chucks) and correct speed/feed synchronization.

What if chips pack in a blind hole?
Increase lubrication, clear chips, and adjust cutting data. The spiral flute helps evacuate chips upward.

Can I reorder individual sizes if one wears out?
Yes. Each size is available separately—see the links in “Set Contents”.
