Tool 200i250S015C

Quarter-inch aluminum work gets tricky fast. Small diameter means less surface speed at reasonable RPM, and that usually means built-up edge or poor finish quality. The heat has nowhere to go and chips start welding to the cutting edge.

This 0.25" diameter cutter uses three flutes to distribute cutting load while keeping chip evacuation aggressive.
The R0.015" corner radius strengthens the cutting edge without sacrificing sharpness.
Enough to handle interrupted cuts and varying depths without chipping out.
TiB₂ coating adds wear resistance during longer runs or when surface speeds climb higher than uncoated tools can handle.
Three flutes work because chip load per tooth stays manageable even when pushing feed rates.
Heat stays controlled, built-up edge stays minimal, and surface finish stays consistent through aluminum, copper, and plastics.
