Accupro 2500121 Roughing End Mill 3/4 in 4 Flute Carbide

Product Description

The ACCUPRO 2500121 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from micrograin solid carbide and coated with TiCN, it delivers hardness and wear resistance suited to ferrous and non-ferrous machining. The cutter measures 0.75 inches in diameter with a 1-inch length of cut and a 3-inch overall length, placing it in the stub-length category for added rigidity. Four right-hand flutes with a fine pitch pattern produce a controlled chip load during high-feed roughing passes. Centercutting geometry allows plunge entry. This tool is installed and used by machinists and CNC operators in job shop and production environments.

The 2500121 is suited for roughing passes on milling machines and machining centers where stock removal rate is the priority. Its stub-length configuration minimizes deflection in setups with limited Z-axis clearance. The 0.75-inch shank diameter matches standard ER and end mill holders used in vertical and horizontal milling operations. TiCN coating extends tool life in applications involving cast iron, alloy steels, and similar materials. The fine-pitch flute design manages chip evacuation at higher feed rates without loading the flutes.

Key Features

• Micrograin solid carbide substrate for toughness and edge retention
• TiCN coating improves wear resistance and surface hardness
• Four right-hand flutes with fine pitch for controlled chip load
• Centercutting capable for plunge milling entry
• Stub-length design reduces deflection in tight setups
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for standard 3/4-inch end mill holders and collet chucks on vertical and horizontal milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling and runout specifications. Ensure the spindle is fully powered down and locked out before changing tooling. Verify shank seating depth and holder torque according to the holder manufacturer's specifications. Inspect the cutting edges for chips or coating damage before each use.
