Stier Combination tap bit M4 DIN 3126 HSS-G 1/4" hexagon

The M4 combination tap bit from Stier is a versatile tool that combines the three essential steps of threading into a single product: drilling, tapping, and deburring/chamfering. This innovative design allows for efficient processing of internal threads according to DIN 13, particularly in through holes. The bit is designed for use in drills or cordless screwdrivers with both clockwise and counterclockwise rotation, offering a maximum thread depth of 1.5 times the nominal diameter. It is excellent for processing soft construction steels up to 500 N/mm², as well as automatic steels and construction steels up to 800 N/mm². Additionally, it is conditionally suitable for brass and aluminum. With a hexagonal shank according to DIN 3126, it fits all standard 1/4" extensions, making it a practical tool for various applications.
