Micrograin Carbide 4-Flute End Mill

This 1/8 inch square end mill is made from micrograin carbide with an AlTiBN coating. It targets DIYers and professionals who mill carbon steels, alloy steels, pre-hardened steels up to HRC45, hardened steels up to HRC45, and cast iron. The five-piece set supplies multiple cutters for general application work.

High-Temperature Coating For Sustained Cuts

The AlTiBN coating lubricates the tool for stability at high temperatures and superior wear resistance at high cutting speeds. It offers better heat resistance than TiAlN, TiN, or TiCN coatings. The 0.125 inch shank fits standard imperial collets and holders without requiring special adapters.

Consistent Wear Resistance Under Load

Flutes ground in an ISO-9001 factory deliver repeatable geometry across the set. The micrograin carbide substrate resists wear during extended engagement in materials up to HRC45. The coating maintains cutting performance where uncoated or lesser-coated tools would degrade from heat buildup.

Highlights

  • Micrograin carbide resists wear for longer tool life

Questions about this item

How hard a steel can the AlTiBN-coated carbide flutes cut before they wear out?

The micro-grain carbide with AlTiBN coating is rated for pre-hardened steels up to HRC45 and hardened steels in the HRC40–45 range, so it handles those hardness levels without rapid wear.

Will the cutter run hot or load up during a full day of milling alloy steel?

AlTiBN lubricates the flutes at high temperature and resists wear better than TiAlN, TiN or TiCN, keeping the tool stable during extended high-speed cuts in alloy steels around HB225–325.

What shank size must my collet or holder accept for these 1/8" end mills?

Each mill has a 0.125 inch shank diameter, so your tool holder or collet needs to grip a 1/8" shank.
