Cutting Tools
2
Design:
with axial and radial special cut, which ensures optimal cutting
results. Carbide hole saws achieve long tool lives and can be
reground
several times.
No breakage with increased load. The tapered centre drill
ensures smooth spot drilling (spot marking is not required) and is fixed
using a tightening screw.
Scope of supply: Hole saw incl. drill.
Application:
Can be used on portable and pillar drilling machines.
Note: With pillar drilling machines always choose manual feed.

Carbide Tipped Keyhole Saw
Continued overleaf
2715
Flat cut:
with ejection spring This ejects the drilled part and
protects the carbide teeth during spot drilling. For material
thicknesses up to 4 mm, stainless steel up to 2 mm. From
16–30 mm the hole saw is made in one piece. From 31 mm
with specially hardened bit holders to compensate the torsion
forces. We recommend MK 2/MK 3 from 31 mm. The sturdy
design results in high concentricity. The CAD-optimised rake
angles with special cut ensure high cutting performance and
tool life. For flat material
2722
MBS:
With ejection spring. This ejects the drilled part and
protects the carbide teeth during spot drilling. For material
thicknesses up to max. 10 mm. (With material thicknesses over
6 mm the tool needs to be set down for chips to be emptied
several times.) From 37 mm with specially hardened bit holders
to compensate the torsion forces. We recommend MK 2/MK
3 from 37 mm. The solid construction and further developed
cutting geometry produces significantly better cutting
behaviour associated with a high cutting performance and with
a high cutting performance and service life. For flat material,
but also suitable on raw material and concaved surfaces.
2728
Deep cut:
Without ejection spring. For material
thickness up to 4 mm, stainless steel up to 2 mm.
Especially suited for pipe material and curved surfaces.
