Accupro 120499 Roughing Finishing End Mill 3/8 in Carbide

Product Description

The ACCUPRO 120499 is a solid carbide roughing finishing end mill designed for aggressive material removal and finish profiling in a single tool. Built for pocketing and profiling operations, it features a 3/8-inch diameter with a 37-degree helix angle and a 0.03-inch corner radius that reduces chipping at the cutting edge. The micrograin carbide construction delivers hardness and edge retention under high-feed conditions. With a 1-inch length of cut and a 2.5-inch overall length, it fits standard milling setups without extended-reach adapters. The bright/uncoated finish suits general-purpose machining where coating is not required by the application.

This end mill is suited for pocketing and profiling operations in both manual and CNC milling environments. The single-end, right-hand cutting and right-hand flute direction make it compatible with conventional right-hand spindle machines. The 3/8-inch shank diameter fits standard collets and end mill holders commonly found in vertical machining centers and knee mills. It is typically selected by machinists, toolmakers, and job-shop operators working in ferrous and non-ferrous materials where a combination roughing-finishing pass reduces cycle time.

Key Features

• Solid micrograin carbide construction for edge retention and wear resistance
• 3-flute geometry balances chip evacuation with surface finish quality
• 0.03-inch corner radius reduces edge chipping and extends tool life on profiling passes
• 37-degree helix angle promotes smooth cutting action and reduced cutting forces
• Bright/uncoated finish suitable for general-purpose milling applications
• Single-end design with right-hand cut and right-hand flute direction

Compatibility

Designed as a direct-fit replacement for standard 3/8-inch shank end mill holders and collet systems used in right-hand spindle milling machines. Intended for pocketing and profiling operations per Series AL specifications.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holder torque and runout tolerances. Ensure the spindle is fully stopped and locked before changing tooling. Verify collet or end mill holder bore is clean and free of chips before seating the shank. Confirm helix direction and spindle rotation match before engaging the cut.
