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.

The packaging unit defines the number of articles in one packaging. In the catalog segment you can choose from different packaging units if a pop-up menu is displayed.

Just leave the field empty if you don't know the packaging unit when directly entering the article number in the shopping basket or when importing with Easy-/VarioScan. The packaging unit will be determined automatically.
The article number is made up of the following: VVVVAAABBB
VVVV = 4 digits for prefix number (please note that the first digit is currently always 0)
AAA = 3 digits for dimension part 1
BBB = 3 digits for dimension part 2

Example article number structures:
Example 1: Screw with dimensions of 4x10 mm:
VVVVAAABBB
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
VVVVAAABBB
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:
VVVVAAABBB
04076
Price per packaging unit (PU):
The displayed price is always in line with the displayed packaging, if the PU is 250 the price for 250 units, if the PU is 300 the price for 300 units.

Price with price key representation (PSL):
The price always applies to a quantity ruled through the price key:
Price for 1 unit
Price for 100 units
Price for 1000 units
The quantity shows the number of pieces or units of measure contained in the order or delivery for the respective article.
In contrast to sales packaging and secondary packaging, the disposal costs for chemical-technical products are shown separately. The breakdown of the individual costs can be found on the relevant products and also in the shopping cart, as well as in our General Terms and Conditions (GTC).
