Application
For drilling out broken-off screw taps (HSS, HSSE, HSSE PM) up to a hardness of 65 HRC using bench-type or column-type drills, wet or dry machining at a rotation speed of 1000-2000 rpm in hand-feed or for wet machining on CNC machines at a rotation speed of 1400-2400 rpm and a feed rate of 0.03-0.06 per revolution. The drill bit has a service life of 3 to 5 screw taps.

Execution
Solid carbide-TiN drill bit, with three cutting edges

Advantage

• User-friendly and efficient removal of screw taps saves time and money.
• Innovative cutting geometry ensures high process reliability and a long service life.
