Machine screw tap, through holes

The innovative specialist for general, wide-ranging applications in steels up to a strength of 1,200 N/mm².

The extremely stable, Longlife screw tap for machining hard-to-machine materials (such as Hardox) with extremely high strengths from 1000 up to 1400 N/mm², e.g. excavator shovels, lorry attachments, armour plating, snow ploughs, agricultural machinery, etc.

The professional tool for machining of aluminium and aluminium alloys ≤ 10% silicon. Also suitable for long-chipping plastics, zinc and copper.

The high-performance screw tap with the newly-developed generation of shanks (a combination of polygon and straight shank (Ø M4–M12)) for versatile use with almost all machines and materials, such as conventional steels, stainless steels (e.g. V2A, V4A), titanium, heat-resistant and high-strength steels of up to 1200 N/mm² strength and casting materials. Also suitable for non-ferrous metals, such as aluminium, aluminium alloys, bronze and plastics.

With "Coating Plus" and additional black ring identification.

Long machine nut screw tap with overrun shaft for cutting nuts for metric threads in steel up to a strength of 800 N/mm².
