CMR Carmex Multi-Task Tiny Tools

Carmex is introducing a new and innovative Multi-Task Tiny Tool CMR for Boring, Turning, Facing
and Chamfering with a single tool.
The unique design enables machining of the material without the need for a pilot hole.

The new tool shortens the machining cycle time and the number of tools required - providing
High Productivity.
Effective through coolant hole with a spiral flute, evacuates the chips out of the hole
uninterruptedly.
Unique chip breaker and flute design.
To use with standard SIM toolholders on Swiss Type or CNC lathe machines.
Available in BMK Grade only.

Working Method

The tool penetrates the work piece and produces the hole compliant with the minimum diameter
the tool allows.
The tool can penetrate the material in one pass or several passes depending
on the work piece material, coolant pressure, machine power etc.
The hole can be enlarged by multi radial passes.

Chamfering

The tool is equipped with an additional cutting edge, which is located across the main
front edge. This allows production of an additional 45° chamfer on the work piece without the need to stop
the spindle or processing operation.
