Specification

The versatile screw tap for drilling UNC threads for universal use in steels up to a strength of 1,000 N/mm², stainless steels and non-ferrous metals, such as aluminium, aluminium alloys, bronze and plastics.

For work in an extensive range of materials

The universal geometry allows processing of many different materials.

Long service life and good process reliability

The X allowance ensures an increased service life and process reliability.

Very good adhesion of coolants and lubricants as well as reduced tendency for build-up of materials

The vaporised surface enables coolants and lubricants to stick well and reduces the tendency for deposits to build up.

Notice

Sufficient coolant and lubricant must be added when cutting threads.

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:
