Accupro 2500446 Roughing End Mill 1/2 in 4 Flute Carbide

Product Description

The ACCUPRO 2500446 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from micrograin solid carbide and coated with titanium carbonitride (TiCN), it delivers extended tool life and heat resistance in demanding cutting environments. The 1/2 inch diameter cutter features 4 flutes with a right-hand cutting and right-hand flute direction. Length of cut is 1.25 inches, and overall length is 3 inches. This tool is installed and operated by machinists and CNC programmers working in job shops, production facilities, and maintenance machine shops.

This roughing end mill is suited for hogging out material on ferrous and non-ferrous workpieces where fast stock removal is the priority before finish passes. The regular-length geometry keeps it stable in standard milling setups. The TiCN coating improves surface hardness and lubricity compared to uncoated carbide, making it a practical choice for cutting alloy steels, stainless steels, and cast iron at elevated feed rates. It is a single-end tool, so once the cutting end is worn, the tool is replaced rather than flipped.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiCN coating for improved hardness and reduced heat buildup at the cutting edge
• 4-flute, right-hand cut geometry optimized for roughing passes
• 1/2 inch mill diameter with 1/2 inch shank for direct collet or end mill holder mounting
• Non-centercutting design — not intended for plunge cuts
• Regular-length OAL of 3 inches suits most standard milling machine setups

Compatibility

Designed for use in standard 1/2 inch end mill holders, collet chucks, or milling machine spindles accepting a 1/2 inch shank. Shank diameter tolerance is +0.0001 to -0.0004 inches; mill diameter tolerance is +0.000 to -0.005 inches.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Secure the shank fully in the holder to the recommended gauge line depth before tightening. Confirm spindle speed and feed rate are appropriate for the workpiece material and depth of cut before engaging the tool. This is a non-centercutting tool — do not use it for direct plunge entry into solid material.
