Cleveland C33270 Square End Mill 5/8 in 4 Flute Hss Ticn

Product Description

The CLEVELAND C33270 is a single-end square end mill designed for material removal in milling operations across machining centers and manual mills. Built from high speed steel with a TiCN coating, it offers improved wear resistance and surface hardness compared to uncoated HSS tooling. The 5/8 inch diameter cutter carries 4 spiral flutes at a 30-degree helix angle, producing a 1-5/8 inch length of cut and a 3-3/4 inch overall length. The straight-cylindrical shank with Weldon flat accommodates standard end mill holders and set-screw toolholders. This tool is center-cutting, allowing it to plunge directly into a workpiece.

The C33270 is suited for milling cast iron, non-ferrous metals, and steel in production and job-shop environments. Its regular-length geometry fits tight-clearance setups where extended-reach tooling is not required. Machinists working in CNC machining centers or manual knee mills will find the 5/8 inch shank and 4-flute configuration appropriate for moderate material removal rates and finish passes on ferrous and non-ferrous workpieces. The right-hand cut and right-hand flute direction are standard for conventional spindle rotation.

Key Features

• TiCN coating increases surface hardness and reduces tool wear on ferrous and non-ferrous materials
• 4 spiral flutes at a 30-degree helix angle improve chip evacuation and reduce cutting force
• Center-cutting design allows direct plunge entry into the workpiece
• Straight-cylindrical shank with Weldon flat provides secure seating in set-screw holders
• Right-hand cut and right-hand flute direction for standard CNC and manual mill spindles
• Regular-length geometry suited for short-reach applications without extended-reach tooling

Compatibility

Designed for use with standard 5/8 inch end mill holders, collet chucks, and Weldon-style set-screw toolholders. Primary workpiece materials include cast iron, non-ferrous metals, and steel as specified by the manufacturer for the HG-4C series.

Installation Notes

Installation should be performed by a qualified machinist with the spindle fully powered down and locked out. Seat the shank fully into the toolholder and torque the set screw against the Weldon flat per the toolholder manufacturer specifications. Verify runout with a dial indicator before cutting. Do not exceed the recommended depth of cut for the workpiece material and cutter diameter.
