Accupro 12181499 Corner Radius End Mill 5/8 in 2 Flute Carbide

Product Description

The ACCUPRO 12181499 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 5/8-inch diameter cutting face with a 0.03-inch corner radius that reduces stress concentrations at the cutting edge and produces a controlled blend radius on finished workpiece features. The 1-1/4-inch length of cut (LOC) and 3-1/2-inch overall length (OAL) make it suitable for moderate-depth slotting and peripheral milling. Micrograin carbide construction provides edge retention and wear resistance in ferrous and non-ferrous materials. This is a single-end, centercutting tool, meaning it can be used for plunge entry as well as side milling passes.

This end mill is suited for use in CNC machining centers and manual knee mills where a controlled corner radius is required on part features such as pockets, slots, and profiled edges. The right-hand cut and right-hand flute spiral are standard for conventional and climb milling on common CNC setups. The bright uncoated finish is appropriate for non-ferrous materials, aluminum, and general-purpose steel cutting at appropriate speeds and feeds. Machinists and tool-and-die professionals in job shops, production facilities, and maintenance machining applications will find this a standard-fit tool for radius blending work.

Key Features

• 0.03-inch corner radius reduces edge chipping and produces a consistent blend radius on milled features
• Micrograin solid carbide construction for edge retention and rigidity
• Centercutting design allows direct plunge entry into workpiece material
• Two-flute geometry provides good chip clearance in slotting and pocket milling
• 40-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Bright uncoated finish suitable for non-ferrous and general-purpose machining applications

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills accepting a 5/8-inch straight shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder or collet. Seat the shank to the full recommended engagement depth in the tool holder to minimize runout and avoid pullout under cutting loads. Verify speeds and feeds against the workpiece material and consult the tooling manufacturer's cutting data before beginning the operation.
