Accupro 310037 Square End Mill 3/16 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 310037 is a solid carbide square end mill designed for precise milling of ferrous and non-ferrous materials in machining applications. This single-end tool features a 3/16 inch cutting diameter, a 5/16 inch length of cut, and a 38-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The AlTiCrN coating provides thermal and wear resistance, extending tool life under high-speed and dry-cutting conditions. With four spiral flutes and a variable index design, the 310037 reduces harmonic vibration during cuts. Machinists and CNC operators working in job shops, tool rooms, and production environments are the primary users of this tool.

The ACCUPRO 310037 is suited for milling operations on steel, stainless steel, cast iron, and similar materials where a tight-tolerance square shoulder or slot is required. The 3/16 inch shank diameter matches the cutting diameter, making it compatible with standard collet chucks and end mill holders of that bore size. It is used in vertical machining centers, CNC mills, and manual knee mills where a compact, short-reach end mill is needed. The 2 inch overall length keeps the tool rigid in applications that do not require extended reach.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiCrN coating for extended tool life in high-temperature cutting conditions
• 38-degree helix angle for efficient chip evacuation and reduced cutting forces
• Variable index flute spacing reduces harmonic vibration and chatter
• Centercutting design allows plunge milling operations
• Right-hand cut and right-hand spiral for standard spindle rotation

Compatibility

Designed as an OEM-style replacement end mill for use in standard 3/16 inch collet chucks and end mill holders on vertical machining centers and CNC milling machines.

Installation Notes

Installation is performed by a machinist or CNC operator. The tool must be seated fully in a clean, undamaged collet or end mill holder before tightening to the holder manufacturer's specification. Inspect the shank and collet bore for chips or debris before loading. Ensure the machine spindle is fully stopped and the machine is in a safe state before changing tooling.
