Cleveland C42124 Ball End Mill 0.5 in 2 Flute Hss

Product Description

The CLEVELAND C42124 is a single-end ball end mill designed for finishing operations in ferrous and cast iron materials. Built from high speed steel with a standard uncoated finish, this tool delivers consistent performance on manual and CNC milling machines. The 0.5 inch diameter ball nose geometry produces smooth contoured surfaces and blended radii without secondary finishing passes. With a 30-degree right-hand helix and two spiral flutes, the C42124 provides efficient chip evacuation and stable cutting action at typical finishing feeds and speeds. It belongs to the HG-2B series and is suited for tool rooms, job shops, and maintenance machining environments.

This end mill is intended for finishing passes in cast iron and steel workpieces. The ball nose profile makes it well suited for 3D contour milling, pocket blending, and radius profiling. With a 1 inch length of cut and 3.25 inch overall length, it fits standard R8, CAT, BT, and collet-style toolholders using a 0.5 inch bore. Right-hand cutting direction is compatible with conventional CNC and manual knee mill setups. The regular-length shank and compact reach design keep deflection low during light finishing cuts.

Key Features

• Ball nose geometry for contoured surfaces and radius blending
• High speed steel construction handles cast iron and steel workpieces
• 2-flute spiral design promotes chip evacuation during finishing passes
• 30-degree right-hand helix reduces cutting forces and improves surface finish
• Uncoated finish suitable for use with cutting fluids or dry cutting on softer steels
• Single-end configuration with regular-length shank for low overhang and reduced deflection

Compatibility

Designed as an OEM-style replacement or direct-use tool for standard 0.5 inch bore milling toolholders used in CNC machining centers and manual knee mills performing finishing operations on cast iron and steel.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank fully into a clean, properly sized collet or end mill holder and torque the retention mechanism per the toolholder manufacturer's specification. Inspect the cutting edges for chipping before each use. Do not exceed the recommended axial depth of cut for finishing passes with high speed steel tooling.
