200 Series

Tool 200i375L015C

Built-up edge formation accelerates when chip load exceeds aluminum's adhesion threshold. The interface temperature spikes, aluminum particles weld to the cutting edge, and surface finish degrades rapidly. Most failures trace back to per-tooth loading that's too aggressive for the alloy being cut.

The 200i375L015C distributes cutting load across three flutes rather than two.
Lower chip load per tooth reduces the heat generation that drives aluminum adhesion to carbide substrates.
The R0.015" corner radius strengthens the cutting edge at the most vulnerable point while reducing peak stress concentration during entry.
TiB₂ coating provides the low-friction surface chemistry aluminum requires.
Unlike AlTiN coatings that promote aluminum pickup, TiB₂ maintains separation between workpiece and tool even during demanding roughing passes where heat buildup is unavoidable.
