Blue ring, HSS-Co, type B

Prime quality for application in series production. Ultra-modern manufacturing technology for maximum productivity.

Application area:

Through hole for steel

Field of Application:

Screw tap for metric ISO thread DIN 13

Advantages:

Geometry

• Special groove geometry for low-friction chip removal
• Designed for long-chipping materials

Coating/surface

• TiN (titanium nitride) coating to prevent the formation of built-up edges, inhibits the adhesion of material
• Coating ensures a smoother surface in the groove and in the thread profile
• Surface smoothing ensures reduced torque

Recommended applications

• Cutting speed vc = 10-20 m/min
• Use of cooling emulsion 6-8 %, or alternatively oil cooling

Area of application

• Steels up to 1000 N/mm²; structural and case-hardening steels, spheroidal graphite iron, black malleable iron

Advice:

Up to M 10 DIN 371 (reinforced shaft)/from M 12 DIN 376 (with thin shaft)
