Accupro 12182201 Square End Mill 3/4 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12182201 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. With a 3/4 inch cutting diameter, a 1 inch length of cut, and a 40-degree helix angle, this tool delivers aggressive chip evacuation and smooth cutting action. The AlTiN coating provides heat resistance and extended tool life in high-temperature cutting environments. Constructed from micrograin solid carbide, it maintains edge integrity under high feed rates. This end mill is a single-end, centercutting design, allowing plunge cuts in addition to peripheral and slot milling. It is installed and operated by machinists and CNC tooling professionals.

This end mill is suited for milling ferrous and non-ferrous metals in both conventional and climb milling strategies. The stub-length profile keeps deflection low in short-reach applications. With a 3/4 inch shank diameter matching the cutting diameter, it seats directly in standard ER or straight-bore toolholders without a reduction collet. The right-hand cut and right-hand spiral flute configuration is compatible with standard CNC machining center spindle rotation. Three flutes balance chip load and surface finish across a range of materials including steel, stainless, and cast iron where AlTiN coatings perform well.

Key Features

• 3/4 inch cutting diameter with mill diameter tolerance of +0.000 / -0.002 inches for consistent fit
• AlTiN finish for high-temperature resistance and extended tool life
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge entry without pre-drilled pilot holes
• Micrograin solid carbide substrate for rigidity and edge retention
• Right-hand cut, right-hand spiral flute — compatible with standard CNC spindle rotation

Compatibility

Designed as a direct-fit replacement or new installation in standard 3/4 inch straight-bore or collet-style toolholders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the minimum recommended insertion depth per the toolholder manufacturer guidelines to prevent pullout under load. Verify runout with a dial indicator after installation before engaging the workpiece.
