Micro 100 VHSM-030-5 3mm 5-Flute 0.3mm Rad Carbide Corner Radius End Mill

The Micro 100 VHSM-030-5 is a new, solid carbide, 5-flute corner radius end mill designed for high-speed machining (HSM) of ferrous and non-ferrous materials in micro and precision applications. The part number decodes as follows: VHSM = Variable Helix Square End Mill (corner radius variant per Micro 100 series convention), 030 = 3.0 mm cutting diameter, 5 = 5 flutes; published specs confirm a 0.3 mm corner radius, 6 mm length of cut, and 50 mm overall length with a 6 mm straight shank. The 5-flute geometry increases chip load per tooth and improves surface finish relative to 4-flute equivalents, and the variable helix is engineered to suppress harmonic chatter during aggressive radial engagement passes. The uncoated solid carbide substrate (bright/uncoated finish confirmed by photo — no coloring or TiN/AlTiN tint visible) is suited for aluminum, brass, and plastics at high RPM; the 6 mm shank accepts standard ER11, ER16, or collet-style toolholders common in CNC machining centers and high-speed spindles.
