Accupro 14883511 Square End Mill 1/64 in 3 Flute Carbide

Product Description

The ACCUPRO 14883511 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. Built from micrograin carbide and left bright/uncoated, it features a 1/64 inch (0.0156 inch) cutting diameter with a 5/64 inch (0.0780 inch) length of cut and a 30-degree helix angle. The three-flute, right-hand spiral configuration provides efficient chip evacuation and smooth cutting action. With a 1/8 inch shank diameter and 2-1/2 inch overall length, this single-end tool is suited for CNC machining centers and manual milling machines requiring small-diameter, high-precision cutters.

This end mill is intended for use in precision machining environments where small-diameter cutting is required, such as engraving, slotting, and fine detail work on ferrous and non-ferrous materials. Its micrograin carbide substrate supports rigidity and edge retention at small diameters. The bright/uncoated finish makes it well-suited for non-ferrous materials including aluminum, brass, and copper. Machinists and CNC operators working in tool and die, mold making, prototype fabrication, and general precision machining will find this tool appropriate for close-tolerance micro-milling work.

Key Features

• 1/64 inch (0.0156 inch) cutting diameter for micro-milling applications
• Solid micrograin carbide construction for rigidity and edge retention
• 3-flute, right-hand spiral flute design for efficient chip removal
• 30-degree helix angle balances cutting forces at small diameters
• Centercutting geometry allows plunge entry cuts
• Bright/uncoated finish suited for non-ferrous and soft material applications
• Single-end design with 1/8 inch shank for standard collet compatibility

Compatibility

Designed for use in standard 1/8 inch collets or ER-style collet chucks on CNC machining centers and manual mills. Part of the ACCUPRO ASQSC3-CC-30H series of small-diameter square end mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or tool holder that matches the 1/8 inch shank diameter and inspect the collet for wear before clamping. At this diameter, tool runout must be minimized — verify holder and spindle concentricity before engaging the cut to avoid tool breakage.
