Accupro 14556430 Corner Radius End Mill 1/2 in 4 Flute Altin+

Product Description

The ACCUPRO 14556430 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hardened materials. It features a 0.5-inch mill diameter, a 1-inch length of cut, and a 0.02-inch corner radius that reduces stress concentration and extends tool life at the cutting edge. The AlTiN+ coating provides high-temperature oxidation resistance, making this tool well-suited for dry machining and high-speed applications. With 4 flutes and a right-hand spiral flute geometry, it delivers efficient chip evacuation and smooth surface finishes. Machinists and CNC operators in production shops and tool rooms are the primary users of this tool.

This end mill is suited for milling slots, profiles, and pockets in steel, stainless steel, cast iron, and similar ferrous alloys. The centercutting design allows for plunge entry, adding versatility in programming. The single-end configuration and 3-inch overall length make it compatible with standard CNC machining centers and manual mills using a 1/2-inch collet or end mill holder. It belongs to ACCUPRO Series 6/44 and is built to micrograin carbide standards for consistent performance in high-feed and high-speed operations.

Key Features

• AlTiN+ coating for high-temperature wear resistance in dry and semi-dry machining
• 0.02-inch corner radius reduces chipping and extends tool life at corners
• Centercutting design enables direct plunge entry without a pre-drilled hole
• 4-flute right-hand spiral geometry supports efficient chip evacuation and fine surface finish
• Micrograin solid carbide substrate provides rigidity and edge retention
• Straight-cylindrical shank fits standard 1/2-inch collet chucks and end mill holders

Compatibility

Designed as an OEM-style replacement and standard production cutting tool for CNC machining centers and manual mills accepting a 1/2-inch straight-cylindrical shank. Part of ACCUPRO Series 6/44.

Installation Notes

Installation is performed by CNC machinists or toolroom personnel. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into a clean, properly sized collet or end mill holder and torque the retention device according to the holder manufacturer's specifications. Inspect the corner radius and cutting edges for chips or damage before each use.
