Cleveland C33680 Square End Mill 0.75 in 2 Flute Hss Tin

Product Description

The CLEVELAND C33680 is a double-end, two-flute square end mill manufactured from high speed steel with a titanium nitride (TiN) finish. Designed for material removal and profiling operations, it features a 0.75-inch mill diameter, a 1.3125-inch length of cut, and a 5.625-inch overall length. The spiral flute geometry and 30-degree helix angle promote efficient chip evacuation and smooth cutting action. Right-hand cut and right-hand flute orientation are standard. Centercutting capability allows the tool to plunge directly into the workpiece. This tool belongs to the HD-2 series, indicating a heavy-duty application profile suited for production and general-purpose milling work.

This end mill is rated for use on cast iron, non-ferrous metals, and steel. It fits standard milling machines, vertical machining centers, and manual knee mills that accept a 0.75-inch straight shank with Weldon flat. The double-end configuration extends tool life by providing two usable cutting ends, making it a practical choice for shops focused on reducing tooling cost per part. Machinists and tool-and-die professionals performing slotting, profiling, and peripheral milling operations will find this tool suited to regular-length cutting requirements.

Key Features

• Double-end design provides two cutting ends for extended tool life
• TiN coating increases surface hardness and reduces friction at the cutting edge
• 30-degree helix angle with spiral flute for efficient chip evacuation
• Centercutting geometry allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute orientation for standard spindle use
• Straight-cylindrical shank with Weldon flat for secure tool holding

Compatibility

Designed as a standard 0.75-inch shank replacement or new-installation end mill for milling machines and machining centers accepting straight-cylindrical or Weldon flat tool holders. Rated for cast iron, non-ferrous metal, and steel workpiece materials per HD-2 series specifications.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully into the tool holder, engaging the Weldon flat set screw to prevent axial pullout under load. Verify spindle speed and feed rate against material and tool diameter recommendations before engaging the cut. Inspect both cutting ends for edge condition before each use and replace the tool when chipping or wear is visible.
