Silver 1/2 inch 4-flute TiCN end mill, single square end

Cleveland Golf

Cleveland Golf HG-4C 1/2 In. 4-Flute TiCN End Mill

SKU CH-ANW6-28QXZ

A 1/2-inch high-speed steel end mill with four flutes and a TiCN finish for finishing operations

  • Product typeHole, Drill, Bore & Wire Gauges
  • Square end with zero corner radius gives sharp finishing profiles
  • TiCN coating extends tool life in general-purpose milling
  • Four-flute design improves surface finish on ferrous materials
  • 30-degree helix angle balances chip evacuation and edge strength
  • 1/2-inch shank matches standard holders for secure clamping

Purpose & User

This square end mill is a high-speed steel cutter designed for general-purpose finishing operations in ferrous and non-ferrous materials. Machinists and toolmakers who need a reliable single-end tool for profile milling, slotting, or light roughing will find the four-flute geometry suitable for producing smooth surface finishes on manual or CNC machines.

Build & Mounting

The cutter features a straight 1/2 inch shank that matches its cutting diameter for direct collet or end-mill holder mounting without adapters. A TiCN coating increases surface hardness and wear resistance compared to uncoated tools, extending life in stainless steel, titanium, and high-temperature alloys. The 30-degree helix angle promotes stable chip evacuation, while the sharp corner radius of .000 inches leaves a true square profile at the bottom of a cut.

Thermals, Noise & Power

High-speed steel construction tolerates moderate cutting temperatures without the brittleness of carbide, reducing the risk of catastrophic fracture during interrupted cuts. Four flutes distribute cutting forces evenly, which lowers vibration and spindle load at typical finishing feeds and speeds. The coated flutes reduce friction, helping to control heat buildup in the workpiece and tool during extended passes.

Questions about this item

What does the 30-degree helix angle mean for chip evacuation on this end mill?

The 30-degree helix angle provides a balanced cutting action suitable for general-purpose finishing, helping move chips away from the cutting zone without excessive vibration.

What tool holder or collet size matches the 1/2-inch shank diameter?

Use a 1/2-inch ER collet, Weldon flat holder, or end mill holder with a matching 1/2-inch bore to secure the shank properly.

How do I install this single-end mill without damaging the TiCN coating?

Clamp the uncoated shank only, ensure the flutes clear the holder face, and tighten to the holder manufacturer's torque spec to prevent slippage.
