Accupro 12182276 Square End Mill 3/16 Inch 3 Flute Carbide

Product Description

The ACCUPRO 12182276 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It features a 3/16 inch cutting diameter, a 1 inch length of cut, and a 4 inch overall length, placing it in the long-reach category. Three spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth cutting action. The AlTiN coating improves heat resistance and extends tool life in dry or semi-dry cutting conditions. Right-hand cut and right-hand flute geometry are standard for conventional milling machine setups. The micrograin carbide substrate provides the hardness and wear resistance required for production environments.

This end mill is suited for slotting, profiling, and peripheral milling operations on machining centers and manual mills. The centercutting design allows plunge entry directly into the workpiece without a pre-drilled hole. The long overall length and 1 inch length of cut make it appropriate for applications requiring reach into pockets or stepped features. It is a single-end tool intended for use in CNC machining centers, knee mills, and similar setups where a 3/16 inch shank is compatible with the collet or toolholder in use.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• AlTiN coating for elevated heat resistance in high-speed and dry cutting
• 40-degree helix angle with spiral flutes for smooth chip flow
• Centercutting geometry allows direct plunge milling
• Right-hand cut and right-hand flute configuration
• Long-length classification with 4 inch overall length for extended reach

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 3/16 inch collets and toolholders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool changer or collet is properly locked before inserting or removing the end mill. Verify collet size matches the 3/16 inch shank diameter to prevent tool slippage. Follow your machine manufacturer guidelines and applicable shop safety standards when setting tool offsets and runout tolerances.
