Konekierretappi M24x1.5 DIN-374C R40 (6H) HSSE

For professionals who demand precision in through-hole threading, this M24x1.5 machine tap in HSSE cobalt steel stands apart with a DIN 374C profile and reinforced shank. The C-form chamfer with 2–3 lead threads reduces cutting force and improves chip evacuation in high-volume production. Unlike standard taps, the 6H tolerance class ensures a consistent, gauge-accurate fit in steel, alloyed steel, and stainless steel workpieces.

Highlights

• Metric fine thread M24 × 1.5 mm, right-hand, straight flute
• HSSE high-speed steel with cobalt for heat resistance and longer tool life
• DIN 374C standard with reinforced shank for stable clamping
• Chamfer form C (2–3 threads lead) optimized for through holes
• Thread tolerance class 6H for precise internal threads

In daily use

Mount this tap in a rigid holder or synchronous tapping chuck. The reinforced shank diameter of 18 mm and square drive size of 14.5 mm ensure secure torque transfer. Use a suitable cutting fluid to reduce friction and heat. The straight flute design works best in through holes where chips can fall forward. With an overall length of 140 mm, it fits standard tapping machines and CNC machining centers.
