Accupro 12181623 Square End Mill 15/64 in 2 Flute Carbide

Product Description

The ACCUPRO 12181623 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 15/64 inch (0.2344 inch) mill diameter, a 3/8 inch length of cut, and a 1/4 inch shank diameter, this stub-length tool is built for rigidity in tight setups. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide, this uncoated end mill delivers consistent performance in ferrous and non-ferrous materials. It is installed by machinists and CNC operators working in production shops, tool rooms, and job shops.

This end mill is suited for slotting, profiling, and peripheral milling operations where a short, rigid tool is required. The stub length of 2 inches overall keeps deflection low in applications with limited Z-axis clearance. The centercutting geometry allows plunge entry, expanding its use to pocketing operations. Right-hand cut and right-hand flute configuration are standard for conventional CNC milling setups.

Key Features

• 15/64 inch (0.2344 inch) mill diameter with a tolerance of +0.000 / -0.002 inches
• Solid micrograin carbide construction for hardness and wear resistance
• 40-degree spiral helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece
• Stub length (2 inches OAL) maximizes rigidity and minimizes deflection
• Right-hand cut and right-hand flute for standard CNC spindle compatibility

Compatibility

Designed as a standard 1/4 inch shank square end mill compatible with collets, end mill holders, and tooling chucks sized for 1/4 inch shank diameters on vertical and horizontal CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool changer or spindle is locked out before changing tooling. Seat the shank fully in the collet or holder and torque the retention system to the machine manufacturer specification. Verify runout with a dial indicator before beginning a cut, and confirm feed and speed parameters match the workpiece material.
