  • Two-flute geometry clears chips efficiently in finishing passes
  • 30-degree helix angle balances strength and chip evacuation

Square End Mill for Finishing

The Cleveland Golf HDC-2-TC is a cobalt square end mill built for finishing work. Its TiCN coating adds wear resistance for general-purpose milling. The tool suits machinists who need a fractional-inch cutter with a right-hand helix. It is not for buyers who need a roughing profile or a larger cutting diameter.

Sustained Cutting Behaviour

The 30-degree helix angle promotes steady chip evacuation during longer passes. Two flutes and a centre-cutting design keep the tool engaged through the full 3/8-inch length of cut. Cobalt substrate resists heat buildup when the cutter stays in contact with the workpiece. The TiCN finish helps maintain edge integrity under continuous load.

Installation and Common Issues

The 3/8-inch shank fits standard holders for quick mounting. Double-end geometry provides a backup cutting end once the first wears down. A .000 corner radius leaves a sharp intersection that can chip if feed rates are excessive. Verify tool clearance before starting to avoid holder interference.

Questions about this item

How much heat does the 1/8" cobalt double-end mill generate when running continuously?

Heat output depends on the material being cut, spindle speed, feed rate and coolant use; the tool itself has no built-in thermal rating.

What machine setup is required to use the 3/8" shank on this double-end mill?

A milling machine or CNC with a 3/8" collet or end-mill holder, rigid spindle and appropriate speed range for cobalt tooling.

Will the 30-degree helix angle work with older manual knee mills?

Yes, the 30-degree helix is standard for general-purpose finishing and is compatible with conventional manual mills when proper speeds and feeds are used.
