  • 5/16 inch shank fits standard inch tool holders
  • ISO 9001 factory grinding ensures consistent edge quality

Micrograin Carbide End Mill for Hardened Steels

The SPEED TIGER ISE5-16-4T is a square end mill designed for general milling of carbon steels, alloy steels, pre-hardened steels, hardened steels and cast iron. It targets machinists and fabricators who need a reliable cutter for tough ferrous materials.

4-Flute Geometry with AlTiBN Coating

The tool uses micrograin carbide ground in an ISO 9001 facility for consistent flute geometry. Its AlTiBN coating provides lubricity and heat resistance at high cutting speeds, outperforming TiAlN, TiN or TiCN alternatives for extended wear life in demanding metalworking applications.

Verify Shank Diameter and Material Compatibility

Confirm your tool holder accepts a 0.3125 inch shank before ordering. The cutter is optimised for steel and iron; it is not intended for aluminium, titanium, Inconel or non-ferrous carving tasks where different geometries or coatings are recommended.

Questions about this item

What does the AlTiBN coating on this 4-flute end mill allow at high cutting speeds?

The AlTiBN coating lubricates the tool for stability at high temperature and provides superior wear resistance at high cutting speeds with better heat resistance than TiAlN, TiN or TiCN coatings.

What shank diameter does the ISE5-16-4T end mill have for tool-holder fit?

The shank diameter is 0.3125 inches, matching the cutter diameter for direct collet or holder clamping.

How is the ISE5-16-4T end mill installed, and what step is often missed?

Clamp the 0.3125-inch shank fully into a matched collet or holder, tighten to spec, then verify flute clearance; the step often missed is confirming the tool is seated to the correct depth before tightening.
