Design:
HSS, DIN 335-C, bright surface. 90° countersink angle. Axial
and radial taper-ground and CBN deep-ground. With straight, u-shaped
clamping slots and drilling spaces ground from full pieces. Also provided
with cutting and clearance angles for the most common materials.
Application:
Suitable for universal chatter and burr-free drilling,
countersinking and deburring work for countersunk screws DIN 963,
DIN 964, DIN 965, DIN 966 and DIN 7991 in one step. Please note the
large countersink range!
The excellent cutting properties and easy machining process result
from the cone-shaped back taper on the coat and angle of rake. The
countersink achieves the best results with the strongest feed and lowest
cutting speed.
Note:
Sufficient supply of coolant is essential.
