Accupro 12181498 Corner Radius End Mill 5/8 in 2 Flute Carbide

Product Description

The ACCUPRO 12181498 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 5/8-inch diameter with a 0.02-inch corner radius, a 1-1/4-inch length of cut, and a 3-1/2-inch overall length. The 2-flute, single-end, centercutting geometry allows it to plunge directly into the workpiece as well as perform standard peripheral and slot milling. The micrograin carbide construction provides edge stability and wear resistance at higher feeds and speeds. This tool is installed and operated by machinists and CNC programmers working with vertical machining centers, manual mills, and similar equipment.

This end mill is suited for finish and semi-finish milling passes in ferrous and non-ferrous materials where a small corner radius is required to strengthen the tool-workpiece interface and reduce stress concentrations. The bright uncoated finish makes it appropriate for applications where coating interaction with the workpiece material is a concern, or where the tool will be resharpened. The right-hand cutting direction and right-hand spiral flute geometry are standard for conventional CNC and manual milling setups.

Key Features

• 5/8-inch mill diameter with 5/8-inch shank for a straight, non-reduced shank profile
• 0.02-inch corner radius reduces chipping at the cutting edge and extends tool life
• 1-1/4-inch length of cut and 3-1/2-inch overall length suit medium-depth cavities and pockets
• Micrograin solid carbide construction for dimensional stability and edge retention
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Bright uncoated finish compatible with a wide range of materials and regrinding
• 40-degree helix angle promotes smooth chip evacuation and reduced cutting forces

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 5/8-inch collet or end mill holders used in vertical machining centers, CNC milling machines, and manual knee mills requiring a corner radius end mill configuration.

Installation Notes

Installation is performed by a machinist or CNC toolroom technician. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Seat the shank fully into a clean, undamaged 5/8-inch collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout at the tool tip with a dial indicator before beginning a cut to confirm proper seating and minimize premature edge wear.
