Accupro 14797133 Square End Mill 0.01 in 3 Flute Carbide

Product Description

The ACCUPRO 14797133 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 0.01 inch cutting diameter and a 0.015 inch length of cut, this tool is built for micro-machining work where dimensional accuracy is critical. The three-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation while maintaining rigidity at small diameters. The micrograin carbide substrate provides the hardness and edge retention required for fine-detail cuts in ferrous and non-ferrous materials. Installation and use are handled by machinists and CNC programmers operating vertical machining centers, milling machines, and similar equipment.

This end mill is suited for micro-milling operations in precision machining environments including mold-making, medical device components, electronics fixtures, and small-part production. The extended-reach design, with a 0.05 inch reach length, allows access to recessed features without compromising tool rigidity. The bright, uncoated finish makes it appropriate for a wide range of base materials where a coated tool is not required. The 1/8 inch shank is a standard size compatible with collet systems commonly found on CNC machining centers and manual knee mills.

Key Features

• 0.01 inch cutting diameter with a tight mill diameter tolerance of +0.0000 / -0.0010 inches for precise, repeatable cuts
• Micrograin solid carbide construction for superior hardness and edge retention at micro scales
• Three-flute, right-hand spiral flute design with 30-degree helix angle for efficient chip removal
• Center-cutting capable — allows plunge entry directly into workpiece material
• Extended-reach geometry with 0.05 inch reach length for machining recessed or deep-pocket features
• Bright, uncoated finish suitable for dry or lubricated cutting across a range of workpiece materials

Compatibility

Designed for use in standard 1/8 inch collet systems on CNC vertical machining centers, manual knee mills, and similar equipment used in precision micro-machining applications.

Installation Notes

This end mill is installed and operated by machinists using standard ER or equivalent collet systems sized for 1/8 inch shanks. Always confirm collet bore size and shank diameter tolerance match before seating the tool. Verify spindle runout is within acceptable limits before running micro-diameter tooling, as runout errors are proportionally larger relative to tool diameter at this scale. Follow machine manufacturer guidelines for spindle speed, feed rate, and depth-of-cut recommendations when working with tools in the sub-0.1 inch diameter range.
