RUKO HGB-DIN352-HSSCo-60°-M-6x1.00mm HSS-Co machinetap

This RUKO machine tap stands out with its cobalt-alloyed high-speed steel construction, which maintains hardness at elevated temperatures and suits demanding production environments. The DIN 352 geometry with a 60° chamfer and medium lead handles both through holes and blind holes in steels up to 800 N/mm².

Highlights

• HSS-Co material resists heat and wear for longer tool life
• Metric coarse thread M6 × 1.00 mm to DIN 352
• Medium lead (approx. 4–5 threads) for balanced chip evacuation
• Right-hand cutting direction
• Bright finish

In daily use

The tap’s three flutes provide stable guidance and efficient chip removal. The 4.9 mm square drive fits standard tap wrenches, while the 6.0 mm shank diameter ensures secure clamping. With a thread length of 18 mm and an overall length of 58 mm, it reaches into deep holes without sacrificing rigidity.
