Accupro 12182446 Square End Mill 15/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12182446 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 15/64 inch (0.2344 inch) cutting diameter, a 3/4 inch length of cut, and a 1/4 inch shank diameter, with an overall length of 2-1/2 inches. The 4-flute, right-hand spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN (Titanium Carbonitride) coating over micrograin carbide substrate provides increased surface hardness and wear resistance for extended tool life in demanding cuts.

This end mill is suited for slotting, profiling, and peripheral milling operations on ferrous and non-ferrous materials. The centercutting geometry allows plunge entry, making it practical for pocketing operations without a pre-drilled pilot hole. Its regular-length body fits standard toolholders and collet chucks on vertical machining centers and CNC mills. Machinists working with stainless steel, alloy steels, and hardened materials will find the TiCN finish and micrograin carbide grade appropriate for maintaining edge integrity under moderate to high chip loads.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiCN coating increases surface hardness and reduces tool wear
• 4-flute, 40-degree right-hand helix spiral flute for efficient chip removal
• Centercutting design enables direct plunge entry into workpiece
• Right-hand cut and right-hand flute orientation for standard spindle rotation
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fitment

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 1/4 inch collet or toolholder setups on CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank fully within the collet or toolholder to the recommended engagement depth before tightening; never allow the flute relief to seat inside the collet. Verify spindle speed and feed rate against the material being cut prior to operation. Inspect the cutting edges for chipping or wear before each use and replace the tool if edge condition is compromised.
