Accupro 12182236 Square End Mill 1/8 in 3 Flute Carbide Ticn

Product Description

The ACCUPRO 12182236 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. Built from micrograin carbide with a TiCN (titanium carbonitride) finish, this single-end mill delivers hardness and wear resistance in demanding cutting applications. The 3-flute, spiral-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 3 inches overall length with a 1-inch length of cut, it falls into the extra-long category, making it suitable for deeper pocket milling and extended-reach setups. Centercutting capability allows plunge cutting without a pre-drilled entry point. Installed by machinists and toolroom operators working on CNC mills and manual milling machines.

This end mill is sized for light, precise work in tight spaces and deep cavities. The 1/8-inch diameter and 1/8-inch shank fit standard collets and toolholders sized for that bore. The extra-long overall length at 3 inches provides reach into deep slots and pockets where standard-length tools cannot access. The right-hand cut, right-hand flute configuration is the conventional setup for standard CNC and manual milling operations. Typical applications include slot milling, profiling, and pocket milling in tool steels, stainless, aluminum, and other machinable alloys.

Key Features

• Micrograin solid carbide construction for extended tool life in hard materials
• TiCN coating increases surface hardness and reduces friction at the cutting edge
• 40-degree helix angle with spiral flute geometry for efficient chip evacuation
• Centercutting design allows direct plunge entry without pre-drilling
• Extra-long 3-inch OAL provides extended reach into deep pockets and slots
• Right-hand cut and right-hand flute for standard milling machine setup

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC and manual milling machines equipped with collet systems or toolholders accepting a 1/8-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Seat the shank to the full recommended grip depth in the collet or toolholder and torque the retention nut according to the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before use, as micrograin carbide is rigid and can fracture if mishandled during installation.
