Step drill for railing 6-18mm HSS-XE Titan-TEC with spiral groove, Karnasch

Double-edged cobalt step drill specially designed for drilling railings
Suitable for metal, steel, stainless steel, acrylic glass and non-ferrous metals, sheets and beams

Range: 6-18mm
Diameters: 6 - 8 - 10 - 12 - 14 - 16 - 18 mm
Number of blades: 2

Shank diameter: 10mm, with three anti-rotation faces in the chuck
Overall length(vč. stopwatch): 67mm

Max. thickness of drilled material: 4mm / 6mm

Step 12 mm - for mounting beams and spacers(extended drilling step - 6mm minimizes the risk of accidental enlargement of the hole)
Step 18 mm - for railing beams and housing profiles(extended drilling step - 6mm for double drilling / 2 railings in 1 working step)
The stop at the end of the drill prevents the drill from falling inside the profile during drilling - it protects both the drill and the hands.

Material: HSS-XE - high-alloy cobalt high-speed HSSE steel(68 HRC)
Coating: TITAN-TEC, increases the life of the drill when drilling with very limited cooling(spray, paste), as well as when dry cutting. We recommend using cutting oil.

Smaller diameters can be drilled at higher speeds, with increasing drilling diameter it is necessary to reduce the cutting speed and speed. Failure to maintain the speed or overheating the drill may cause it to become dull.

Transitions to a larger diameter also perfectly needle the drilled hole.

Thanks to the spiral groove, the drilling is smooth, the chips do not stick, low cutting forces, the drilled material has fewer burrs and the tool has a longer endurance.

Suitable for galvanized materials, optimal cutting behavior due to constant cutting angles.
There is no tilting of the drill during cutting - no work injuries
