TRINBOR 6-37MM HSS-ALTIN

The drill head for step drilling is made of HSS (high-speed steel) and coated with AlTiN
(aluminum titanium nitride). This provides the longest possible lifespan and does not require
the use of coolant. Laser-marked numbers in both spiral grooves provide highly visible and
durable marking of the hole diameter. In addition  the 3-flat shank prevents slipping in the
drill chuck and provides efficient transmission with high torque. The HSS drill head for step
drilling delivers smooth  burr-free drilling in multiple diameters with a single drill head. It
is ideal for deburring  drilling round holes  and enlarging existing ones. It is not necessary
to mark center points because the two-part tip provides easy starting. Its CNC-ground spiral
groove allows optimized chip removal and less vibration for smooth drilling. The most optimal
cutting edge and absolute smoothness are ensured thanks to axial and radial clearance grinding.
This step drill bit is suitable for use on thin materials such as non-ferrous metals  sheet
plastic  sheet steel  plastic  and stainless steel. 12 steps Ø 6-9-12.5-15.2-18 .6 -20 .4 -22
