Precision Cobalt End Mill

The Cleveland Golf Cobalt Square End Mill is a double-ended fractional-inch cutter with a 1/8 inch milling diameter and four flutes. It carries a TiCN finish for wear resistance and a 30 degree helix angle for stable finishing passes. The 3/8 inch shank fits standard collets and holders. Machinists running general-purpose profiling or slotting jobs on ferrous and non-ferrous stock will find the tool ready for immediate use.

Check Holder And Workpiece

Verify that your tool holder accepts a 3/8 inch shank and provides enough gauge length for the 3-1/16 inch overall length. Confirm the machine spindle can run right-hand cutting at the speeds cobalt requires without excessive runout. Ensure the workpiece material and fixturing suit a 3/8 inch length of cut and a square corner profile with zero corner radius. Coolant delivery should reach the cutting zone to maximise the TiCN coating life.

Replaces Worn Single-End Tools

This double-ended design replaces two worn single-end mills, effectively doubling the cutting edges per tool change. The upgrade is worth it when changeover time dominates cycle cost or when a zero-radius square corner is specified on the print. Shops running high-mix finishing work gain flexibility without stocking multiple diameters. Buyers needing longer reach or ball-nose profiles should look elsewhere.

Questions about this item

Does the box include anything besides the cobalt square end mill itself?

The listing covers the single double-ended 1/8-inch cobalt square end mill with TiCN finish; no holders, collets or additional cutters are mentioned.

When would I choose this 1/8-inch four-flute double-end version over another size or flute count?

Choose this 1/8-inch diameter, four-flute, double-end tool when you need a small rigid cutter for finishing slots or profiles in a 3/8-inch shank holder.

What does the 30-degree helix angle mean for chip evacuation and finish quality in practice?

A 30-degree helix gives a balanced shear action that clears chips reliably while producing a smooth finish on general-purpose materials.
