Description
Version:
Robust unbreakable construction with variable toothing on flexible special steel body (bimetal). The reinforced stiff base is equipped with thread and drive pin holes (from ⌀ 32 mm) for secure mounting on the arbor. The high quality of the HSS teeth, the teeth geometry and the tight manufacturing tolerances guarantee the best cutting performance and tool life.
- Vario toothing 4/6 tpi for low vibration.
- Maximum depth of cut for all sizes 38 mm.
Application:
On pillar drills, lathes or hand-held power drills at the appropriate speed. For cutting circular holes from thin-walled to thick-walled material with a flat or convex workpiece surface. Suitable for all materials such as steel, stainless steel, brass, copper, cast iron, light metal, wood, plasterboard and plastic panels etc. Use of lubricant will give increased tool life (metals).
Recommendation:
The use of cutting oil such as No. 084205 size 0.25 extends the service life and permits more rapid progress through the material.
