Accupro 12182515 Square End Mill 0.315 in 4 Flute Carbide

Product Description

The ACCUPRO 12182515 is a solid carbide square end mill designed for precision milling in metal fabrication and machining applications. Built from micrograin carbide stock, it carries a TiCN (Titanium Carbonitride) coating that increases surface hardness and reduces friction during cutting. The 4-flute, right-hand spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 0.315 inches in diameter with a 0.7874-inch length of cut, this tool is sized for finish milling, slotting, and profiling work on ferrous and non-ferrous materials. It is centercutting, allowing plunge cuts without a pre-drilled pilot hole.

This end mill is suited for use in CNC machining centers and manual mills in job shop, production, and toolroom environments. The regular-length geometry makes it a standard choice for general-purpose side milling, contouring, and shallow pocket work where rigidity and precision tolerances are the priority. Machinists and CNC operators working with steel, stainless steel, cast iron, and similar materials will find the TiCN finish and micrograin substrate well matched to those cuts.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• TiCN coating for increased hardness and reduced tool wear
• 4-flute right-hand spiral design with 40-degree helix angle for efficient chip removal
• Centercutting geometry enables direct plunge entry without a pilot hole
• Matched shank and mill diameter at 0.315 inches for straightforward collet setup
• Right-hand flute direction compatible with standard CNC spindle rotation

Compatibility

Designed as a standard single-end square end mill for use in CNC machining centers and manual milling machines accepting 0.315-inch (8 mm) collet or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank in a clean, properly sized collet or end mill holder and torque the drawbar or clamping mechanism per the machine tool manufacturer specifications. Verify runout with a dial indicator before commencing a cut. Inspect the cutting edges for chips or damage before each use and replace the tool if the TiCN coating shows significant wear or the flutes are compromised.
