Accupro 12183495 Square End Mill 5/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12183495 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. It features a 5/16 inch cutting diameter with a 1 inch length of cut and a 4 inch overall length, placing it in the long-length category. The 4-flute, spiral-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and surface finish quality. Micrograin carbide construction delivers the hardness and wear resistance required for ferrous and non-ferrous cutting applications. This is a single-end, uncoated tool sold individually.

This end mill is suited for general-purpose milling work including slotting, profiling, and peripheral cuts in a wide range of materials. The centercutting design allows plunge entry directly into the workpiece, making it versatile for both roughing and finishing passes. Right-hand cut and right-hand flute orientation are standard for conventional CNC and manual milling setups. It is installed and operated by machinists, tool-and-die makers, and manufacturing technicians working with vertical or horizontal milling machines and machining centers.

Key Features

• Solid micrograin carbide construction for hardness and extended tool life
• 4 spiral flutes with 40-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge milling entry
• Long-length designation with 1 inch length of cut for deeper reach applications
• Right-hand cut, right-hand flute for standard CNC and manual mill compatibility
• Uncoated finish suitable for use with cutting fluid in a broad range of materials

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills accepting a 5/16 inch straight shank end mill.

Installation Notes

This end mill is installed by qualified machinists and tooling technicians. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank in a properly sized collet or end mill holder to the tool manufacturer and machine specifications. Verify runout with a dial indicator before beginning cutting operations to protect tool life and workpiece accuracy.
