Accupro 12183772 Square End Mill 1 Inch 5 Flute Solid Carbide

Product Description

The ACCUPRO 12183772 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. It features a 1-inch cutting diameter, a 2-inch length of cut, and a 4-inch overall length, making it well-suited for standard-reach profiling, slotting, and peripheral milling. The 5-flute geometry paired with a 45-degree helix angle promotes efficient chip evacuation and smooth cutting action at higher feed rates. An AlTiN (aluminum titanium nitride) coating provides heat resistance and extended tool life when cutting ferrous and hardened materials. This end mill is intended for use by machinists and CNC operators in job shop, production, and toolroom settings.

This end mill is appropriate for milling steel, stainless steel, cast iron, and similar ferrous alloys, particularly where elevated cutting temperatures are a concern. The centercutting design allows for plunge entry in addition to conventional side and slot milling. The right-hand cut and right-hand spiral flute configuration is compatible with standard CNC machining centers and manual knee mills. The 1-inch shank diameter fits standard R8, CAT, BT, and other common toolholding systems that accept a 1-inch straight shank. It is a single-end tool sold individually.

Key Features

• 1-inch cutting diameter with a 2-inch length of cut for standard-reach applications
• 5-flute design supports higher feed rates and improved surface finish compared to 4-flute geometry
• 45-degree helix angle promotes aggressive chip evacuation and reduced cutting forces
• AlTiN coating extends tool life in high-temperature ferrous and hardened-material cutting
• Centercutting geometry allows plunge milling without a pre-drilled entry hole
• Micrograin solid carbide substrate provides rigidity and wear resistance

Compatibility

Designed as an OEM-style replacement or direct application end mill for CNC machining centers, vertical mills, and manual knee mills accepting a 1-inch straight shank in standard toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool is secured in a clean, properly sized collet or end mill holder before tightening. Verify runout with a dial indicator after installation to confirm concentricity within acceptable tolerance. Follow the machine tool manufacturer and cutting tool manufacturer guidelines for speeds, feeds, and depth-of-cut when setting up this tool.
