The HOZLY compression end mill listing, bullet by bullet

Five bullets: a combination of upper and lower cutting edges; high-precision grinding, wear and heat resistance and rigidity; no burrs with up and down spiral machining; efficiency; and use on CNC machining centres, woodworking machines and advertising routers.

HOZLY’s compression spiral

Up at the bottom, down at the top. A compression cutter pulls fibres inward from both faces, so plywood edges come out clean on both sides. The 22 mm cutting length is the edge available along the flute.

HOZLY and collet size

The shank is 4 mm. The Genmitsu router reviewed on this site lists a 1/8 in collet, which is 3.175 mm; a 4 mm shank needs a 4 mm collet.
