WTL-303-04
3 Flute Extra Length Solid Carbide Upshear Router
0.125-in Dia 3-Flute End Mill, 1-in LOC, 0.125-in Shank, 3-in OAL


3 Flute Extra-Long Solid Carbide Upshear Router — reach for thick stock and deep profiles
- 3 flute solid carbide upshear spiral router in EXTRA-LONG length for thick stock, deep profiling, and long-reach trimming
- 30° helix, square end with corner chamfer
- WTL-303 sizes: 1/8"–3/4" dia.; flute lengths 1"–3"; overall lengths 3"–5-1/4" (e.g. 3/4" dia. × 3" flute × 5-1/4" OAL)
- Tighter cutting-diameter tolerances than WU/WD: 1/8" = −.0001/−.0002; 3/16"–3/4" = −.000/+.001; shank dia. −.0001/−.0002; OAL ±.060
- Applications: slotting, side milling, helical interpolation, ramping, roughing, semi-finishing — dry, wet, cold air, or spray mist
- Materials: wood, aluminum, copper, magnesium, brass, plastics
- Diamond-Like Carbon (DLC) coating available
- 3 flutes give more cutting edges per revolution than the 2-flute WU1/WD1 — higher feed rates at CNC production speeds
