摘要
The invention is a monolithic end-mill cutter set (A) that can be made of ceramic and/or other materials having high strength and toughness and comprising a shank part (B) along a longitudinal axis (4) and a cutter part (C), comprising: a cutting diameter (1) varying between 2 to 20 mm, at least one web thickness (18) found at a blade (26) part, at least one helix angle (10) having a cutting edge (13) thereon, a core diameter (16) that is at least 0.7 times the cutting diameter (1), at least one corner radius (5) found at the tip part of the blades (26) between the flutes (9) and axial and positive radial rake angles (17) at which cutting operation is made. It has a wide helix angle interval and a positive rake angle. Titanium Aluminium Nitride TiAlN coating can be made on the monolithic end-mill cutter set (A) via PVD coating method in order to extend the service life of the end-mill cutter set (A), increase the abrasion resistance, and minimize the problem of sticking of rake on the cutter set (joining).
