The short HSS combination screw tap with unique SMART STEP technology for highly precise drilling, thread cutting and countersinking/deburring in a single operation.

3 in 1: drilling, thread cutting and countersinking/deburring in one work step

No tool change required, saving time and costs

The first combination screw tap with stepped drill bit tip geometry

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)

1/4 inch hexagon mount

Prevents spinning in the drill chuck, ensures optimal power transmission and protects the drill chuck from damage

Product packaging made of 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified^® Bronze

Available exclusively from Würth

Notice

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.

Application area

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

Instructions

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.
