Hardmetal company Kyocera Corporation has developed a new line of indexable modular drills with a chemical vapor deposition (CVD) coated insert on the outer edge and a physical vapor deposition (PVD) coated insert on the inner edge.

Magic Drill DRV is suitable for hole drilling in the machine tool business and the automobile, aviation and medical device industries.

With previous indexable drills, PVD-coated inserts were adopted for both the outer and inner edges, which has the disadvantage of increased wear and tear on the outer edge because it comes into contact with the workpiece material at a higher speed. To solve the problem, this new model adopts a CVD-coated insert with heat and wear resistance for the outer edge and a PVD-coated insert for the inner edge so that stable processing can be achieved even if a strong force is applied to the inner edge.

The new drill is now capable of deep drilling up to 6D (six times the holder diameter) for the first time, the company says.
