WIDIA Top Cut 4 high-perf. drill bit w. index. ins. 3xD 23x25x155.8 mm C w. IC

Application

High-performance drilling in the diameter range of 12.00 mm–55.00 mm and at drilling depths of 3xD for the steel, stainless steel, aluminium and cast iron material groups. With medium requirements for surface quality and tolerance

Execution

• Four easily selectable cutting material types and four chip shape geometries for machining steel, stainless steel, aluminium, cast iron as well as superalloys and titanium

Advantage

• Four true cutting edges per indexable insert for the entire range
• trouble-free application for cross-drilled holes, inclined inlet and outlet holes, chain holes, convex entry surfaces and drilling in half cylinder
• Internal and external indexable inserts are designed to prevent mix-up
• The X-offset design is used to adjust the hole diameter on lathes and to optimize the tolerances on machining centres

Notes

warning: when the drill passes completely through the workpiece, a disc is created. if the workpiece is rotating, the disc will be flung away! appropriate safety precautions are required!
