Cleveland Golf

Cleveland Golf 1/4in 4-Flute HSS Square End Mill

SKU CH-1YDF-B32R9

A 1/4-inch high-speed steel square end mill with four flutes for general-purpose finishing cuts

  • TypeHole, Drill, Bore & Wire Gauges
  • High-speed steel withstands heat during general-purpose milling
  • Four flutes give a smoother finish on steel and aluminium
  • 30-degree helix angle clears chips efficiently from the cut
  • Bright uncoated surface reduces cost for short-run jobs
  • 1/4-inch cutting diameter with 1-1/4-inch length of cut

Precision Finishing Tool

The Cleveland Golf square end mill is a general-purpose cutter machined from high-speed steel for milling operations that require a clean, squared corner. Its four-flute design and 30-degree helix suit machinists and fabricators producing finished profiles in a range of ferrous and non-ferrous materials.

Four-Flute Centre-Cutting Geometry

The single-end tool carries four flutes with a centre-cutting configuration, allowing it to plunge directly into the workpiece before moving laterally. This flute count balances chip evacuation with core strength, making it the decisive feature for finishing passes where dimensional accuracy and surface finish are the priority.

Uncoated HSS Thermals

The bright, uncoated high-speed steel body runs hotter than coated carbide alternatives, so flood or mist coolant is recommended to manage heat during extended cuts. Cutting forces remain moderate at the 1/4-inch diameter, keeping vibration and spindle load low on manual or CNC knee mills.

Questions about this item

How does the 1/4 inch milling diameter perform in a real machine?

The 1/4 inch milling diameter removes material with a 1-1/4 inch length of cut on a 2-7/16 inch overall tool, suited for general-purpose finishing in fractional-inch setups.

What does the 30 degree helix angle cap in practice?

The 30 degree helix angle provides standard chip evacuation and cutting stability for right-hand rotation across steel and non-ferrous metals.

What does the 3/8 inch shank diameter need to fit or mount?

The 3/8 inch shank diameter requires a matching 3/8 inch collet, end-mill holder or Weldon flat holder for secure clamping in the spindle.
