STEPPED SPIRAL DRILL BIT TiAIN

With deburring zone. Metric ISO sizes

according to EN 50262.

• Drilling and deburring of sheet metal, pipes

and profiles up to maximum material thickness

of 5.5mm in one operation.

• Spiral grooves - low required force, better

drilling performance, longer service life.

• Relief-ground deburring zone - deburring on

both sides up to material thickness of 1.5mm.

• Turned shaft with ground driving flats - no

twisting in the chuck.

• Conical transition to the shaft at the end of the

last drill step - problem-free withdrawal after

drilling with largest diameter.

• Laser-engraved step diameters inside both

grooves - indicated current size of bore hole

during drilling.

• Speed indications for steel and CrNi steel on

the cone surface.

TiAIN Coating:

• Titanium Aluminium Nitrade.

• Temperature stability up to 800

o

C.

• Surface hardness 3300HV - ceramic-smooth.

• Surface prevents friction.

• Higher cutting speeds - time savings.

• Longer service life - tool cost savings.

Application hints for TiAIN:

• Observe uniform forward feed.

• Observe speed table.

• Do not cool or lubricate the tool!
