Mitsubishi Materials Corporation Metalworking Solutions Company (Company President: Kazuo Ohara Address: Marunouchi, Chiyoda-ku, Tokyo) has announced that the launch of the DXAS exchangeable head type carbide drills will take place on October 1^st.

The DXAS range of exchangeable head drills from the TRISTAR drill series, is a new generation of drills that follows the DVAS solid carbide range. These drills provide customers with three main benefits of reduced running costs, together with both high precision and high efficiency

Main features of the DXAS exchangeable head drills:

• Designed to achieve surprisingly long tool life and dramatically reduced running costs. Together with improved accuracy and efficiency, hole quality comparable to conventional solid carbide drills can be achieved.
   
• With the perfect centering feature that minimizes misalignment between the centre axis of the head and the holder when tightening, accuracy comparable to holes drilled by solid carbide type drills can be achieved.
   
• The two-screw tightening suppresses deformation of the holder and achieves high-strength fastening. This secure clamping provides reliability even under high-load conditions, therefore machining efficiency can be greatly improved.
   
• The low resistance cutting edge geometry dramatically improves machining stability when drilling low-rigidity workpieces. It also contributes to improved machining efficiency and reduced power consumption.
   
• The DXAS drills are available from Ø18 - Ø30 mm, in lengths L/D=1.5-8.

Successful examples of Significant Improvements in Tool Life and Machining Efficiency

A 1.7 times improvement in machining efficiency, enabled an astonishing 8.8 times tool life. Thereby greatly increasing overall machining efficiency.
