Accupro 12182529 Square End Mill 3/8 in 4 Flute Carbide

Product Description

The ACCUPRO 12182529 is a solid carbide square end mill designed for precision material removal in milling operations. With a 3/8 inch cutting diameter and 4-flute spiral geometry at a 40-degree helix angle, this tool delivers efficient chip evacuation and smooth cutting performance. The uncoated micrograin carbide construction provides rigidity and edge retention in a range of workpiece materials. At 2.5 inches overall length with a 7/8 inch length of cut, it fits standard tool holders using a 3/8 inch shank. Machinists and tool-and-die professionals use this style of end mill for slotting, profiling, and peripheral milling on manual and CNC machining centers.

This end mill is suited for light to medium-duty milling in ferrous and non-ferrous materials where an uncoated carbide tool is appropriate. The centercutting design allows plunge entry directly into the workpiece, expanding its use in pocketing and ramping operations. Right-hand cut and right-hand flute orientation match the majority of standard spindle configurations on vertical machining centers and knee mills. The regular-length geometry makes it well suited for general-purpose work where extended reach is not required.

Key Features

• Solid micrograin carbide construction for edge rigidity and wear resistance
• 4-flute spiral design with 40-degree helix angle for efficient chip evacuation
• Centercutting geometry enables plunge, ramp, and pocket milling
• Right-hand cut and right-hand flute for standard spindle compatibility
• Uncoated finish suitable for applications where coating is not required
• Mill diameter tolerance of +0.000 / -0.002 inches for dimensional consistency

Compatibility

Designed as a standard 3/8 inch shank square end mill for use in collet chucks, end mill holders, and shrink-fit tooling systems compatible with 3/8 inch shank diameters on CNC and manual machining centers.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures and machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing tooling. Verify shank seating depth and runout with a dial indicator before committing to a cut. Follow your machine tool manual for recommended clamping torque on collet nuts and set screws.
