Kyocera's DRV Magic Drills Reduce Chattering

Kyocera Precision Tools has added several milling and turning solutions for a wide variety of applications. These include larger diameters for the DRV Magic Drill line, a helical endmill for titanium alloy machining, smaller diameters for the M-Six milling cutters and new PVD coating technology for small-part machining. 

The DRV Magic Drill family of indexable drills is now available in larger diameters from ½" to 2" and 12 mm to 60 mm sizes. The drills’ optimal web thickness design creates low cutting forces and reduces chattering for smooth drilling applications, providing precision with less variation in hole diameter, according to the company. They’re suited for high-speed drilling in a range of materials, with 2×D and 6×D capabilities. 

The DRV drills have a chemical vapor deposition outer insert and a physical vapor deposition (PVD) inner insert, which account for different speeds and forces exerted on each cutting edge. The drills use inserts with four cutting edges and four chipbreaker designs for various applications.

The Mecht is a helical end mill engineered for stable titanium alloy machining. Kyocera says its deep flutes and coolant-through holes provide good chip evacuation and improve machining reliability and efficiency.

A smaller diameter range is now available for the company’s M-Six (MFWN) series milling cutters. The additional cutter designs of the MFWN-Mini feature a smaller insert size with a 5-mm depth of cut and the same double-sided, six-edge design from the M-Six line. Face mills are available in diameters from 50 mm to 125 mm, and end mills are available in diameters from 25 mm to 80 mm.

PR17 Series insert grades use Kyocera's MegaCoat Nano Plus technology, which is said to provide improved wear resistance for longer tool life and a high-quality surface finish.
