Accupro 12176983 Square End Mill 3/4 in 4 Flute Carbide

Product Description

The ACCUPRO 12176983 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. With a 0.750 inch mill diameter, a 1.5 inch length of cut, and a 4.0 inch overall length, this tool is built for aggressive material removal while maintaining tight tolerances. The AlTiN coating provides thermal resistance and extended tool life in high-speed ferrous and non-ferrous cutting applications. The 40-degree helix angle promotes smooth chip evacuation and reduces vibration at the cutting edge. This end mill is typically installed by machinists and CNC operators on vertical mills, machining centers, and manual knee mills.

This end mill is suited for slotting, profiling, and peripheral milling in a range of materials including alloy steels, tool steels, stainless steels, and hardened materials where AlTiN coatings perform best. The left-hand spiral flute with right-hand cut geometry is engineered to pull chips upward and away from the workpiece, reducing recutting and heat buildup. It fits standard 3/4 inch ER collets, end mill holders, and shrink-fit toolholders used in both CNC and manual machine setups.

Key Features

• Solid carbide micrograin substrate for superior hardness and wear resistance
• AlTiN finish for high-temperature performance and extended tool life in ferrous materials
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting design allows plunge milling operations
• Right-hand cut with left-hand flute direction for upward chip flow
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit in precision holders

Compatibility

Designed for use with standard 3/4 inch end mill holders, ER collet chucks, and shrink-fit toolholding systems on CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer torque and runout specifications for the toolholder in use. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Verify holder bore cleanliness and check runout with a dial indicator before beginning cuts. Consult the machine tool and toolholder manufacturer guidelines for proper clamping depth and pull-out prevention.
