Accupro 12184981 Square End Mill 4-flute Altin Carbide

Product Description

The ACCUPRO 12184981 is a solid carbide square end mill designed for both roughing and finishing operations in a single tool. It features a 4-flute, right-hand cutting geometry with a 40-degree helix angle and a chipbreaker profile that breaks chips into smaller segments to improve evacuation and reduce heat buildup. The AlTiN coating adds oxidation resistance and surface hardness, making this tool well-suited for aggressive cuts in ferrous and hardened materials. At 0.051 pounds, it is a compact stub-length tool built for rigidity in close-tolerance work. Licensed machinists and CNC operators working in job shop or production environments rely on this style of end mill for efficient material removal without tool changes.

This end mill is used in milling operations where a single tool must handle both stock removal and finish passes. The stub-length design minimizes deflection during high-feed roughing passes and maintains dimensional accuracy through the finishing pass. It is appropriate for use in vertical machining centers, CNC mills, and manual knee mills equipped with a collet or end mill holder sized for a 0.25 inch shank. Applications include slotting, peripheral milling, and shoulder milling in ferrous alloys, stainless steel, and similar hard materials.

Key Features

• 4-flute right-hand cutting geometry with 40-degree helix angle for efficient chip flow
• Chipbreaker profile reduces chip load and heat in roughing passes
• AlTiN coating provides oxidation resistance and extended tool life in hard and abrasive materials
• Stub-length design increases rigidity and reduces deflection
• Single-end tool with square end type for flat-bottom cuts and sharp corner profiles
• Solid carbide construction maintains edge integrity at elevated cutting speeds

Compatibility

Designed as an OEM-style solid carbide stub-length end mill for use in standard 0.25 inch collets and end mill holders on CNC or manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Secure the shank in a clean, properly sized collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the cutting edges and coating for chips or damage before each use. Never exceed the recommended speed and feed parameters for the workpiece material and cut depth.
