Cleveland C41644 Square End Mill 1 in 2 Flute Hss

Product Description

The CLEVELAND C41644 is a 2-flute, single-end square end mill manufactured from high speed steel (HSS), designed for milling operations in ferrous and non-ferrous metalworking applications. It features a 1 inch cutting diameter, a 1-5/8 inch length of cut, and a 4-1/2 inch overall length. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation while maintaining edge stability across a range of materials. Centercutting capability allows the tool to plunge directly into the workpiece, adding operational flexibility. This tool ships uncoated and is suited for machinists, toolroom operators, and CNC setup technicians working in production and job-shop environments.

The C41644 belongs to the HG-2 series and is appropriate for milling cast iron, non-ferrous metals, and steel in standard-reach, straight-shank configurations. The straight-cylindrical shank with Weldon flat accommodates standard end mill holders and set-screw style tool holders found on vertical mills, knee mills, and CNC machining centers. It is a regular-length tool suited for general-purpose peripheral and face milling, slotting, and profiling cuts where extended reach is not required.

Key Features

• 1 inch cutting diameter with 1-5/8 inch length of cut for standard-depth slotting and profiling
• 2-flute geometry supports aggressive chip clearance in softer steels and non-ferrous materials
• 30-degree right-hand helix with right-hand cut for conventional and climb milling
• Centercutting design allows direct plunge entry without a pre-drilled hole
• High speed steel construction provides toughness and regrindability without coatings
• Straight-cylindrical shank with Weldon flat fits standard set-screw end mill holders

Compatibility

Designed for use in standard end mill holders and Weldon-style tool holders accepting a 1 inch straight shank. Intended for machining cast iron, non-ferrous metals, and steel. Part of the Cleveland HG-2 series of general-purpose high speed steel end mills.

Installation Notes

Install in a properly sized end mill holder and torque the set screw against the Weldon flat per the tool holder manufacturer's specification. Confirm spindle runout is within acceptable limits before beginning a cut to preserve edge life. Power down and lock out the machine spindle before changing or inspecting the tool. HSS end mills are regrindable — inspect cutting edges for chipping or wear before each use and remove from service when edge condition degrades.
