Cleveland C41630 Square End Mill 3/4 in 2 Flute Hss

Product Description

The CLEVELAND C41630 is a 2-flute, square-end, single-end mill machined from high speed steel (HSS) and designed for general-purpose material removal in milling operations. It carries a 3/4-inch cutting diameter with a 1-5/16-inch length of cut and a 3-7/8-inch overall length. The straight cylindrical shank with Weldon flat measures 3/4 inch in diameter for secure tool holding. A 30-degree right-hand spiral flute geometry promotes efficient chip evacuation, and the centercutting design allows plunge entry into the workpiece. This tool is sold individually and is installed by machinists and tool-and-die professionals in manual and CNC milling applications.

The C41630 is suited for milling cast iron, non-ferrous metals, and steel in both job-shop and production environments. Its regular length classification makes it a practical choice for standard-depth slotting, profiling, and peripheral milling where extended reach is not required. The HG-2 series designation indicates a general-purpose HSS end mill line appropriate for a broad range of conventional milling setups.

Key Features

• High speed steel construction for toughness across cast iron, non-ferrous, and steel workpieces
• Centercutting design allows direct plunge milling without a pre-drilled entry hole
• 30-degree right-hand spiral flute promotes efficient chip flow and reduced heat buildup
• Weldon flat on straight cylindrical shank reduces tool pull-out under cutting loads
• Uncoated finish maintains re-sharpening ease and suits a wide range of cutting fluids
• Right-hand cut and right-hand flute geometry matches standard milling machine spindle rotation

Compatibility

Compatible primary workpiece materials include cast iron, non-ferrous metals, and steel. Designed as an OEM-style replacement or direct-fit end mill for standard 3/4-inch straight-shank milling chucks, collets, and Weldon-style end mill holders used in vertical and horizontal milling machines.

Installation Notes

Installation and tool changes must be performed with the milling machine spindle fully stopped and locked out per applicable machine safety procedures. Seat the shank fully into the holder before tightening set screws against the Weldon flat to prevent axial slippage during cutting. Verify runout with a dial indicator before beginning a cut. A licensed machinist or qualified CNC operator should select appropriate feeds, speeds, and cutting fluid for the specific workpiece material and machine.
