Accupro 12181763 Square End Mill 1/2 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12181763 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. Built from micrograin solid carbide, it delivers the hardness and wear resistance needed for extended tool life in ferrous and non-ferrous materials. The 0.5 inch cutting diameter is paired with a 3 inch length of cut and a 6 inch overall length, placing this tool in the extra-long category for deep-reach applications. A 40-degree helix angle and spiral flute geometry promote efficient chip evacuation and smooth cutting action. The AlTiN coating adds thermal resistance, making this end mill well suited for dry or high-speed cutting conditions.

This end mill is used in vertical and horizontal machining centers and manual knee mills where extended reach into deep pockets, slots, or cavities is required. The centercutting design allows direct plunge entry without pre-drilling. The right-hand cut and right-hand flute configuration is standard for conventional CNC and manual mill setups. Machinists and tool-and-die professionals working on molds, dies, and structural components will find the extra-long length of cut particularly useful for accessing deep features that shorter tooling cannot reach.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• AlTiN coating provides thermal and oxidation resistance for dry or high-speed cutting
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting geometry allows direct plunge milling without pilot drilling
• Extra-long 3 inch length of cut enables deep-reach pocket and slot milling
• Right-hand cut and right-hand flute configuration compatible with standard mill spindle rotation

Compatibility

Designed as a standard 1/2 inch shank square end mill compatible with ER, Weldon flat, and shrink-fit toolholders accepting a 0.5 inch shank diameter on CNC machining centers and conventional knee mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify toolholder runout and proper seating depth before beginning a cut, as extended-length end mills are more sensitive to deflection and should be engaged with conservative feed and speed parameters until the setup is confirmed. Follow the machine manufacturer and toolholder manufacturer torque recommendations for the specific toolholder style in use.
