Accupro 315162 Square End Mill 3/8 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 315162 is a solid carbide square end mill designed for precision milling operations in metal cutting and machining environments. It features a 3/8-inch diameter with a 1/2-inch length of cut and a 37-degree helix angle, which promotes efficient chip evacuation and smooth cutting action. The ZrN (zirconium nitride) coating increases surface hardness and reduces friction, extending tool life in ferrous and non-ferrous applications. With three flutes in a right-hand spiral configuration and a micrograin carbide substrate, this end mill delivers a strong balance of rigidity and edge sharpness. It is a single-end, stub-length tool suited for CNC machining centers and manual mills.

This end mill is intended for use in machine shops, tool rooms, and production environments where close-tolerance slot milling, profile milling, and peripheral cutting are required. The stub-length format reduces deflection in short-reach setups and improves rigidity in tight-clearance fixtures. It is centercutting, allowing plunge operations in addition to standard side milling. Machinists, CNC operators, and tooling specialists working with aluminum, steel, stainless, and similar materials will find this geometry suitable for a wide range of general milling tasks.

Key Features

• 3/8-inch mill diameter with a tight tolerance of +0.000 / -0.002 inches for accurate finished dimensions
• ZrN coating reduces heat buildup and extends tool life compared to uncoated carbide
• 37-degree helix angle promotes chip flow and reduces cutting forces
• Micrograin solid carbide substrate provides high hardness and wear resistance
• Centercutting design supports both plunge and peripheral milling operations
• Right-hand cut and right-hand flute spiral for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct tooling selection for 3/8-inch collet or end mill holders used in standard CNC machining centers and manual knee mills requiring a stub-length, 3-flute square end mill.

Installation Notes

This end mill is installed and removed by a qualified machinist or CNC operator using a properly rated end mill holder or collet chuck. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm the shank is fully seated in the holder and that runout is within acceptable limits before engaging a cut. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut for the specific workpiece material.
