CoroDrill 880 Delivers Improved Hole Quality & Longer Tool Life

The reinforced variant of CoroDrill 880 indexable drill will substantially improve production economy in large-diameter hole-making applications. The latest CoroDrill 880 tool body is compatible with a range of insert grades, including a grade based on the company’s new Zertivo technology, which delivers optimized cutting-edge integrity.

 

The enhanced drill body is up to 30% stiffer than its predecessor for applications of four to five times the drill diameter. This gives a more reliable drilling experience and a much better hole quality.
