Step drill for metal 4-20mm HSS with spiral groove and chip breaker TiAlN
Product information
Stepped Spiral Groove Drill 4-20 mm
Diameter: 4-6-8-10-12-14-16-18-20mm
Material: HSS
Coating: TiAlN < br>
Suitable for drilling into structural steel, CrNi steel and non-ferrous metals up to 5mm.
PROGRIP system prevents slipping of the stem in the chuck and optimally transmits torque
Spiral groove guarantees quiet operation and high drilling performance
Edges in a single step
The coating increases the service life of the drill bit but must not overheat!
Procedure: High speed for drilling small diameters, when drilling larger diameters, the need for speed is gradually reduced due to increasing circumferential speed. When the coating overheats, the blade is knocked and the blade has to be sanded.
