Accupro 12181632 Square End Mill 17/64 in 2 Flute Carbide

Product Description

The ACCUPRO 12181632 is a solid carbide square end mill designed for precise material removal in milling operations. It features a 17/64-inch (0.2656-inch) cutting diameter, a 1/2-inch length of cut, and a 5/16-inch shank diameter, with a 2-inch overall length. The two-flute, spiral-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide, this stub-length end mill delivers rigidity and wear resistance suited to demanding machining environments. It is centercutting-capable, allowing plunge entry, and runs with a right-hand cut and right-hand flute configuration.

This end mill is suited for use in CNC machining centers and manual milling machines across job shop, toolroom, and production environments. The stub-length design minimizes deflection during close-tolerance work in ferrous and non-ferrous materials. Its uncoated micrograin carbide construction makes it a practical choice for shops that regrind tooling. Machinists and toolroom operators working in general-purpose milling, slotting, and peripheral cutting applications will find the 17/64-inch diameter useful for tight-tolerance feature work.

Key Features

• 17/64-inch (0.2656-inch) cutting diameter with a tolerance of +0.000 / -0.002 inches
• Solid micrograin carbide construction for rigidity and extended tool life
• 40-degree helix angle with spiral flute geometry for efficient chip flow
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Stub-length (2-inch OAL) body reduces deflection in tight setups
• Right-hand cut, right-hand flute — standard orientation for conventional milling setups

Compatibility

Designed as a general-purpose square end mill compatible with standard 5/16-inch collets and end mill holders on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a properly sized collet or end mill holder rated for a 5/16-inch shank diameter and torque the retention mechanism according to the tool holder manufacturer specifications. Inspect the collet and holder for wear or contamination before seating the tool to ensure runout remains within acceptable limits.
