The Genmitsu V-bit listing, bullet by bullet

Five bullets: ten bits on 1/8 in shanks, five flat and five triangular V-bits at 20, 30, 45, 60 and 90°; alloy steel with sharp edges and resistance to wear, breakage and corrosion; a nano blue coating for hardness and wear resistance; a 0.1 mm tip for clean edges without tear-out; and use in sign making, lettering and V-groove mitre joints in hardwood, plywood, acrylic, laminate, resin, PCB and aluminium.

Genmitsu’s shank and the router

1/8 in. The Genmitsu router reviewed on this site lists a 1/8 in ER11 collet among its specifications. This listing does not name that machine; the shank and the collet simply match.

Genmitsu’s angles

A narrow angle cuts fine lines and deep grooves; a wide one cuts shallow, broad ones. The set covers five angles in two tip shapes.
