Specification

The short HSS combination screw tap with unique SMART STEP technology for high-precision drilling, thread cutting and countersinking/deburring in a single operation. Available in the ORSY^® system cassette.

3 in 1 - Drilling, thread cutting and countersinking/deburring in just one operation

No tool change required, saves time and costs

The first combi screw tap with stepped drill bit tip geometry

Up to 100 % faster than HSS combi screw taps

Optimal centring when working on curved surfaces

Highly precise circular holes as the perfect preparation for the high-quality thread cutting

Low-effort drilling

Through hole threads are true to gauge size according to ISO 2 (6H)

1/4" hex shank

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

Available exclusively from Würth

Compact and practical system cassette suitable for the ORSY^® system with useful details, such as stackability, optimised joint and easy opening

Notice

Generally only suitable for through hole threads with a material thickness of max. 1xD

Countersinks according to DIN 74-1 for countersunk head screws (according to DIN 7991) are not possible

For use in cordless drills as well as on hand-held, pillar and upright drills

Application

Application area

Perfect for through holes in aluminium, brass and plastics up to 1xD (M6 = 6 mm material thickness).

Also ideal for machining sheet metal made of unalloyed and alloyed steels up to 600 N/mm² and malleable iron

Instructions

After the drilling process, it is essential to significantly reduce the rotation speed for thread cutting and countersinking/deburring. The cutting values recommended for the various materials and tool diameters, can be found in the cutting parameter overview.

Use sufficient coolant and lubricant.

Always work straight. Avoid tilting: Risk of tool breakage!

Ensure all threads of the product have left the hole before reversing the combi screw tap. Ignoring this warning could result in torn cutting edges or tool failure.

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 v

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

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).
