Cleveland C42133 Ball End Mill 0.75 in 2 Flute Hss

Product Description

The CLEVELAND C42133 is a single-end ball end mill designed for finishing operations in ferrous and cast iron applications. Built from high speed steel with a 2-flute, right-hand spiral configuration and a 30-degree helix angle, this tool delivers smooth chip evacuation and consistent surface finish in moderate-speed machining setups. The uncoated HSS construction suits shops running conventional cutting speeds without high-heat coatings. With a 0.75 inch mill diameter and 1.625 inch length of cut, the C42133 handles typical finishing passes in pockets, contours, and 3D profiling work. Machinists and tool-and-die shops are the primary users of this type of end mill.

This end mill fits standard machining center spindles and manual knee mills accepting a 0.75 inch shank. The 3.875 inch overall length keeps the tool rigid in most common reach scenarios without requiring extended-reach toolholding. Its right-hand cutting direction is compatible with conventional CNC milling setups. Primary workpiece materials include cast iron and steel, making it a practical choice for general machine shops, mold shops, and maintenance machining environments running ferrous stock.

Key Features

• 1.625 inch length of cut accommodates moderate-depth pockets and 3D surfaces
• 2-flute right-hand spiral design promotes chip clearance during finishing cuts
• 30-degree helix angle balances cutting forces and surface finish quality
• Uncoated high speed steel construction for use in standard cutting-speed applications
• Single-end configuration; Series HG-2B regular-length geometry

Compatibility

Designed as an OEM-style drop-in for standard 0.75 inch shank toolholders used in CNC machining centers and manual mills; suited for finishing ferrous materials including steel and cast iron per Series HG-2B specifications.

Installation Notes

Installation is performed by qualified machinists following standard toolholding procedures. Ensure the spindle is fully stopped and machine is locked out before changing tooling. Seat the shank fully into the collet or end mill holder and tighten to the toolholder manufacturer's specified clamping method. Verify runout with a dial indicator before beginning a cutting pass, particularly for finishing operations where surface quality is critical.
