100 Series

Tool 100i313X015A

Small end mills take the brunt of interrupted cuts and tight corner work. The 0.3125" diameter in this 100 Series puts material removal right where precision matters most. In detailed features where chatter and deflection kill surface finish.

Four flutes keep cutting forces balanced even when the tool is working in confined spaces.
The TiAlSiN coating handles the heat that builds up in smaller cross-sections, extending edge life in steel and titanium applications where thermal cycling would otherwise break down an uncoated edge.
The R0.015" corner radius strengthens the cutting edge against microfractures that start at sharp corners, particularly useful in interrupted cuts on cast iron and harder steels.
In profile milling and detailed feature work, that radius maintains edge integrity through multiple part cycles.
The geometry stays consistent, the finish stays predictable.
