Accupro 12181624 Square End Mill 15/64 in 2 Flute Carbide

Product Description

The ACCUPRO 12181624 is a solid carbide square end mill designed for precision milling operations in metal and composite materials. With a 15/64 inch (0.2344 inch) cutting diameter and a 2-inch overall length, this stub-length tool delivers rigidity in tight-clearance applications. The micrograin carbide substrate supports the TiCN coating, which extends tool life in abrasive and harder workpiece materials. The 2-flute, 40-degree spiral helix configuration promotes efficient chip evacuation. Centercutting geometry allows the tool to plunge directly into the workpiece. Right-hand cut and right-hand flute orientation are standard for conventional CNC and manual milling setups.

This end mill is suited for machinists and toolroom professionals working on CNC machining centers, knee mills, or manual vertical mills. The stub-length format reduces deflection and improves rigidity when milling steel, stainless, aluminum, and similar materials where a short reach is practical. The 1/4 inch shank fits standard ER collets, end mill holders, and other 1/4 inch toolholding systems common in production and job-shop environments.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• TiCN coating extends tool life in abrasive and harder workpiece materials
• 40-degree helix angle promotes smooth cutting action and chip flow
• Centercutting design allows direct plunge entry into the workpiece
• Right-hand cut and right-hand flute, compatible with standard spindle rotation
• Stub-length format reduces deflection in short-reach milling applications

Compatibility

Designed for use in standard 1/4 inch toolholding systems including ER collet chucks and end mill holders on CNC and manual vertical milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Seat the shank fully into the collet or holder and torque the retention nut according to the toolholder manufacturer's specification. Inspect the cutting edges for chips or damage before each use; carbide is brittle and should not be dropped or used in worn toolholding that allows runout beyond the stated tolerance.
