Star Cutter Co. announces the availability of a line of internal coolant drills from Louis Bélet, designed specifically for stainless steels. This drill line is well suited for applications in all fields where stainless steel is used, such as watchmaking, medical, aerospace, automotive and so on.

Machining of stainless grades, such as martensitic and austenitic, is often slow and prone to errors, the company says. To address these challenges, one of the drills in the range (REF 0.376-10) achieves depths of up to 10 × D and at rates that are three to four times faster than previous drills. It also eliminates the need for pecking, resulting in smoother, more productive operations. Further, to eliminate the need for a centering or deburring device, a second drill (REF 0.336H) can be used, with or without a chamfer, to produce a pilot hole.

These drills are designed with a compression chamber that minimizes coolant pressure loss, improving efficiency and accuracy with the drills able to hold concentricity of less than 0.003 mm at the drill tip. Additionally, an increased surface area of the lube holes and their specific shape enable these drills to achieve three times the throughput compared to previous generations.

To tackle complex stainless steels and even superalloys like CoCr (Phynox), Louis Bélet developed a micro-grain carbide specifically for stainless steel applications. The TISI (titanium-silicon) coating reduces friction, decreases heat buildup and prevents burr formation, providing longer tool life. The specialized cutting-edge preparation also provides optimal coating adhesion and durability for longer tool life.
