Conical countersink set DIN 335 HSS-G with U-flute

The 6-piece DIN 335 HSS-G PREMIUM countersink set impresses with its precise machining results and high resilience in daily use. The combination of a U-flute with an unequal scale division and a robust 3-sided shank ensures smooth running, clean countersinks and reliable power transmission – for both stationary and manual applications in conjunction with drills, cordless screwdrivers or bench drills.

The countersink set was developed for professional metalworking. The Form C model with 90° allows for precise countersinking and deburring work while simultaneously enabling low-effort drilling. The special cutting edge geometry results in uniform surfaces and reduced vibrations during machining. This facilitates precise work, even with demanding materials.

The countersinks are suitable for machining alloyed and high-alloy steels, cast iron, stainless steel and special alloys. The TiAIN coating ensures that the cutting performance remains constant, even at high temperatures. The reduced wear contributes to long service lives and enables economical work processes in workshop and industrial use.

Thanks to the stable 3-sided shank, the tools sit securely in the chuck and reliably transmit power. The U-flute supports clean chip removal and improves the smooth running of the countersink. This results in precise-fitting countersinks with high dimensional accuracy and clean edge finishing in a wide variety of applications.

The set includes the following cutters:
6.3 mm, 8.3 mm with 3 cutting edges
10.4 mm, 12.4 mm, 16.5 mm, 20.5 mm with 5 cutting edges
