For improved torque transfer. |

The cylindrical shaft
The absolute minimum: 0 % of its contour consists of
surfaces designed for firmer chucking. So optimum transmission of the torque is not possible.
The result:
The shaft tends to slip in the chuck, where the diameter
of the shaft is smaller than the diameter of the working
part of the tool (especially in the case of tools such as roughing drills, step drills or countersinks).

The three-flats shaft
Only 30 % of the contour permits good transmission of the torque by means of flats.
The result:
The shaft prevents slipping in the chuck despite the flats.
Optimum results are not achieved.
Changing tools is time-consuming for perfect chucking.

ROTASTOP® – Strength from the contour
The contour of the ROTASTOP® tool bit ensures improved
transmission of the torque; ROTASTOP® practically
chucks itself automatically, by means of the rising contours.
The result:
No slipping in the chuck, and precise results when machining metals.
ROTASTOP® allows easy tool changing and longer service lives for the tools.
