The "Micro Bore System" is a revolutionary system that allows you to replace tools such as center drills, gun drills, and boring bits in a single holder (outer diameter 10mm) without changing the core height or the length in the longitudinal direction. The holder is made of stainless steel, so there is no concern about rust. Each bit has grooves or holes for cooling, allowing cutting fluid to be applied directly to the cutting edge. Unlike previous methods where cutting fluid was applied from the outside, this system allows it to come directly from the tool, so you can use it with confidence. 【Features】 ■ Compatible with a wide range of bits ■ Can be used without changing core height or longitudinal length ■ Holder is made of stainless steel and does not rust ■ Cutting fluid is applied directly to the cutting edge ■ The holder is easily attached by hand-tightening the holder cap *For more details, please feel free to contact us.
