Accupro 12181779 Square End Mill 7/32 in 2 Flute Carbide

Product Description

The ACCUPRO 12181779 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. It measures 7/32 inches (0.2188 inches) in diameter with a 1/4-inch shank and a 3-inch overall length. The 1-inch length of cut and extra-long configuration give it reach for deeper pockets and slots. With 2 flutes and a 40-degree helix angle, it produces efficient chip evacuation and smooth surface finishes in a range of materials. Micrograin carbide construction provides hardness and edge retention for demanding cuts. This end mill is centercutting, meaning it can plunge directly into the workpiece.

This end mill is suited for use in CNC machining centers and manual mills working with ferrous and non-ferrous metals, plastics, and composites. The extra-long geometry makes it a practical choice when standard-length tools cannot reach the required depth. The right-hand cut with right-hand spiral fluting is the conventional setup for most vertical milling operations. Machinists and tool-and-die professionals handling production runs or prototype work will find the uncoated micrograin carbide substrate appropriate for a broad range of base materials.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• 40-degree helix angle promotes efficient chip evacuation and reduced heat buildup
• Centercutting design allows direct plunge entry into the workpiece
• Extra-long length type with 1-inch length of cut for deep pocket and slot work
• Right-hand cut and right-hand spiral flute — standard orientation for vertical mills
• Uncoated finish suitable for general-purpose milling across a wide range of materials

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 1/4-inch collets and end mill holders on CNC machining centers and manual vertical milling machines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully in a collet or end mill holder to the manufacturer-recommended engagement depth before tightening. Verify spindle runout is within acceptable limits before cutting to protect the cutting edge and workpiece accuracy. Always confirm the machine is at a full stop before changing or inspecting tooling.
