Cleveland C33093 Square End Mill 13/16 in 4 Flute Hss Tin

Product Description

The CLEVELAND C33093 is a double-end, four-flute square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Manufactured from high speed steel with a titanium nitride (TiN) finish, this tool provides extended wear resistance compared to uncoated HSS. The cutter measures 13/16 inches in diameter with a 1-7/8 inch length of cut and a 7/8 inch shank diameter, giving it adequate reach for slotting, profiling, and peripheral milling in standard machining setups. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces during operation.

This end mill is suited for use in manual mills and CNC machining centers where a right-hand cut, right-hand flute, center-cutting tool is required. The double-end configuration doubles usable tool life, making it a practical choice for production shops and tool rooms running repetitive milling operations. The HD-4C series designation indicates a heavy-duty, four-flute geometry optimized for rigidity and chatter resistance in conventional milling applications. It is typically installed by machinists in job shops, tool and die operations, and maintenance machining environments.

Key Features

• Double-end design extends usable tool life before replacement
• TiN coating increases surface hardness and reduces friction at the cutting edge
• 30-degree spiral flute helix promotes efficient chip evacuation
• Center-cutting geometry allows plunge entry into workpieces
• Right-hand cut and right-hand flute configuration for standard spindle use
• HD-4C series heavy-duty four-flute geometry for rigidity in slotting and profiling

Compatibility

Designed as an OEM-style replacement or direct-use end mill for milling machines and CNC machining centers accepting a 7/8 inch straight shank toolholder.

Installation Notes

Installation is performed by a qualified machinist using an appropriate collet, end mill holder, or Weldon-style set-screw holder sized for a 7/8 inch shank. Ensure the spindle and machine are powered down and locked out before changing tooling. Verify runout with a dial indicator after seating the tool to confirm proper concentricity before cutting. Follow the machine manufacturer and tooling guidelines for speed and feed selection based on workpiece material.
