DDLDDM

The new D-CUT program from Duracarb is a double edge insert solution for parting and grooving. The unique prismatic

top and bottom design of the inserts and corresponding seating design in the holder ensures proper seating and alignment

of the insert resulting in a rigid and secure clamping.

Dedicated D-CUT tool holders are available for groove depths up to 9mm and 16mm, in popular square shank sizes of

16x16, 20x20 and 25x25.

D-CUT insert grades and geometries are suitable for machining a variety of materials like steel, stainless steel, cast iron,

high temperature alloys, brass and aluminium.

TURN TO OUR TOOLS!

REDUCE BURR: Ensure centre height of cutting edge within +/-0.1mm. Use Narrow and sharp geometry insert.

IMPROVE FLATNESS: Minimise tool holder overhang Check alignment and perpendicularity of tool to machine spindle

axis Optimise work piece holding.

IMPROVE SURFACE FINISH: Increase cutting speed. Ensure optimum chip control. Eliminate chatter.

IMPROVE CHIP CONTROL: Choose recommended chip breaker Check alignment and perpendicularity of tool to machine

spindle axis. Increase feed. Increase coolant flow. Minimise tool holder overhang. Use correct parameters.

PREVENT CHIPPING OF CUTTING EDGE: Use recommended grade and geometry. Reduce feed at end of cut.

Eliminate chatter. Increase speed. Eliminate built-up edge. Ensure rigid setup.

PREVENT/REDUCE BUIT-UP EDGE: Use recommended grade and geometry. Increase speed. Reduce feed.

Increase coolant flow/concentration.
