SUMOCHAM DCN 12xD


ISCAR is expanding the drill length options by adding the 12xD depth to diameter ratio, in a diameter range of 8 to 25.9 mm.
The new DCN drills feature cylindrical shanks, which enable clamping of the drill in hydraulic toolholders (most recommended) or in spring collets.
All drill bodies feature helical coolant holes. Prior to using the 12xD drill, it is recommended to drill a pre-hole by using a DCN 1.5xD drill or a centering drill.
Note: The HCP drilling heads enable drilling with 12xD drills without the need for pre-hole preparation.
The new drills can be used in clad plates. The new 12 L/D ratio drills are commonly used in the heat exchanger and other industries.
