  • Five-piece pack supplies multiple cutters for continuous production runs
  • ISO-9001 factory grinding ensures consistent flute geometry across every unit

Micrograin Carbide End Mill 5-Pack

The Speed Tiger ISE1-8-2T set supplies five 1/8 inch square-end mills ground from micrograin carbide with an AlTiBN coating. Each two-flute cutter is built for general-purpose milling of carbon steels, alloy steels, pre-hardened steels up to HRC45, hardened steels in the HRC40 to 45 range, and cast iron. The 1/4 inch shank fits standard collets used by DIYers and professionals alike.

Upgrade From Uncoated Or Single-Flute Bits

The AlTiBN coating delivers superior heat resistance and wear life compared with uncoated tools or basic TiN and TiCN layers, making the jump worthwhile when cutting speeds rise or material hardness reaches the upper HB325 or HRC45 brackets. Shops still running single-flute or lower-grade carbide on tough alloys will see longer edge retention and fewer tool changes.

Fits Standard 1/4 Inch Collets

A 0.25 inch shank lets the mills drop into common ER or DA collet systems without adapters, freeing the spindle for quick swaps across the five-piece pack. The ISO-9001 factory grind ensures consistent concentricity so runout stays low, preserving both workpiece finish and holder life. Buyers needing larger diameters or different flute counts must look elsewhere.

Questions about this item

What shank diameter does the 1/8" end mill need for the collet?

The shank measures 0.25 inches, so a 1/4" collet or holder is required.

How do I install the end mill without damaging the AlTiBN coating?

Insert the 0.25" shank fully into a clean collet, tighten evenly, and avoid side loads that can chip the coating.

When should I replace these cutters when milling hardened steel up to HRC45?

Replace once the AlTiBN coating wears through or flank wear reaches the limit for your tolerance; the micro-grain carbide resists wear but will dull over time.
