- Work up to 100 % faster than with conventional HSS combination screw taps
- Optimal centring even when working on curved surfaces
- High-precision, circular drilling as ideal preparation for the quality of subsequent thread cutting
- Effortless drilling
True-to-the-gauge through hole thread according to ISO 2 (6H)

- Generally only suitable for through hole threads with a material thickness of max. 1xD
- Countersinks according to DIN74-1 for countersunk head screws (according to DIN 7991) are not possible
- For use in cordless drill drivers, handheld drills, drill presses and on pillar drills.
- Perfect for through holes in aluminium, brass and plastics up to 1xD (e.g. M6 = 6 mm material thickness).
- Also ideal for machining sheet metal made from unalloyed and alloyed steels up to 600 N/mm², and from malleable iron
- Significantly reduce the rotation speed for thread cutting and countersinking/deburring after drilling. The recommended cutting parameters for the various materials and tool diameters can be found in the cutting parameter overview.
- Use sufficient coolant and lubricant.
- Ensure to work perpendicular to the material. Avoid tilting: Risk of tool breakage!
- All threads of the combination screw tap must be through and out of the hole before reversing it. Otherwise the tool or the cutting edges might break.
