Accupro 12458516 Square End Mill 0.0394 in 2 Flute Carbide

Product Description

The ACCUPRO 12458516 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 0.0394 inch (1.00 mm) mill diameter and a 0.1181 inch (3.00 mm) length of cut, this tool operates at micro-scale dimensions suited for detailed slot milling, profiling, and finishing passes. The 2-flute, spiral flute geometry with a 30-degree helix angle promotes efficient chip evacuation in both ferrous and non-ferrous materials. Micrograin carbide construction delivers the edge rigidity and wear resistance needed at this diameter. This uncoated end mill is single-end and centercutting, allowing plunge entry. Machinists and tooling professionals working in CNC milling applications install and use this tool.

This end mill is suited for precision CNC milling operations requiring small-diameter tooling. Typical applications include micro-slot cutting, detailed contouring, and finish profiling on components where tight geometries and close tolerances are critical. The 0.1181 inch shank diameter (3.00 mm) fits standard collet systems used in vertical machining centers and CNC routers. Right-hand cut and right-hand flute direction are standard for conventional and climb milling on CNC platforms. It is appropriate for use in tool and die, mold making, medical device machining, and aerospace component work where fine feature detail is required.

Key Features

• 0.0394 inch (1.00 mm) mill diameter for micro-scale milling operations
• Solid micrograin carbide construction for edge rigidity and extended tool life at small diameters
• 2-flute spiral design with 30-degree helix angle for effective chip evacuation
• Centercutting geometry allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute direction for standard CNC milling setups
• Uncoated finish suitable for applications where coating is not required or where regrinding is anticipated

Compatibility

Designed as an OEM-style replacement or direct-use precision end mill compatible with standard 3.00 mm collet systems on CNC vertical machining centers, CNC routers, and similar milling platforms accepting right-hand tooling.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with CNC tooling setup procedures. Ensure the machine spindle is fully powered down and locked out before inserting or removing tooling from the collet. Verify collet size matches the 0.1181 inch shank diameter and that runout is minimized before beginning cuts, as excessive runout at this diameter can cause immediate tool breakage. Follow machine manufacturer guidelines and applicable shop safety standards when setting tool offsets and depth-of-cut parameters for micro-diameter end mills.
