Star SU, Star Cutter Company’s marketing, sales and service affiliate, is releasing a new line of expert internal coolant drills from Louis Bélet, designed specifically for stainless steels. The drill line can be used in all industries where stainless steel is used, such as medical, watchmaking, aerospace, and automotive, among others.

Machining of stainless grades such as martensitic and austenitic, is often slow and prone to errors.  To address these challenges, one of the drills in the new range (REF .376-10) achieves depths of up to 10xd 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. Moreover, to eliminate the need for a centering or deburring device, a second drill (REF .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 <0.003mm at the drill tip, according to the company. 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, ensuring longer tool life. The unique cutting-edge preparation also ensures optimal coating adhesion and durability for longer tool life.
