Accupro 12182261 Square End Mill 5/8 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12182261 is a solid carbide square end mill designed for high-performance milling in metal and alloy applications. It measures 5/8 inch in diameter with a 3-inch length of cut and a 6-inch overall length, making it an extra-long reach tool suited for deep-pocket and extended-reach machining operations. The three-flute configuration with a 40-degree helix angle and spiral flute geometry promotes efficient chip evacuation and reduces cutting forces. An AlTiN coating adds heat and wear resistance for dry or near-dry cutting conditions. Machinists and CNC operators in job shops, aerospace, and general metalworking rely on this end mill for demanding milling work.

This end mill is suited for use in vertical and horizontal machining centers as well as manual mills where an extra-long reach is required. The centercutting design allows for direct plunge entry into the workpiece. The right-hand cut and right-hand flute configuration is standard for conventional and climb milling on most CNC platforms. Micrograin carbide construction provides rigidity and edge retention when working with ferrous and non-ferrous materials at elevated spindle speeds and feeds.

Key Features

• 5/8 inch cutting diameter with matching 5/8 inch shank diameter for direct ER or side-lock collet holding
• 3-inch length of cut supports deep-pocket and extended-reach milling operations
• 40-degree helix angle with spiral flute geometry for smooth cutting action and efficient chip removal
• AlTiN coating provides elevated thermal resistance for dry or high-speed cutting
• Centercutting capability allows direct plunge milling without pre-drilling
• Micrograin solid carbide construction delivers consistent edge integrity and dimensional stability

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard ER, hydraulic, shrink-fit, or side-lock toolholders accepting a 5/8 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator familiar with rotating cutting tool setup. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before loading or unloading the tool. Seat the shank fully to the minimum insertion depth recommended by the toolholder manufacturer to prevent pullout under cutting loads. Verify runout with a dial indicator after clamping before beginning any cut cycle.
