Accupro 14797148 Square End Mill 1/64 in 3 Flute Carbide

Product Description

The ACCUPRO 14797148 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 1/64 inch (0.0200 inch) cutting diameter and a 1/32 inch length of cut, this tool is engineered for micro-scale profiling, slotting, and contouring where control and rigidity are critical. The three-flute, right-hand spiral design runs at a 30-degree helix angle and is center-cutting capable, allowing plunge entry directly into the workpiece. The micrograin carbide construction provides the hardness and edge retention needed for demanding cuts in ferrous and non-ferrous materials. This end mill is installed and operated by machinists and toolroom professionals on CNC machining centers and manual mills.

This end mill is suited for precision work in mold-making, medical component machining, electronics, and aerospace applications where very small features must be held to tight tolerances. The extended reach design, with a 0.1600 inch reach length and a 1/8 inch shank diameter, allows access to recessed areas without tool interference. The uncoated micrograin carbide substrate performs well in a range of materials and is compatible with flood coolant or mist lubrication setups typically found in production and toolroom environments.

Key Features

• 1/64 inch (0.0200 inch) cutting diameter with a tolerance of +0.0000 / -0.0010 inches for consistent dimensional accuracy
• Three-flute spiral design at a 30-degree helix angle for efficient chip evacuation in micro-milling operations
• Center-cutting geometry allows direct plunge entry without a pre-drilled pilot hole
• Extended reach with a 0.1600 inch reach length for machining recessed features and deep pockets
• Micrograin solid carbide construction delivers superior edge retention and rigidity at small diameters
• Right-hand cut and right-hand flute direction suitable for standard CNC spindle configurations

Compatibility

Designed as an OEM-style replacement and direct-fit cutting tool for CNC machining centers and manual mills using a 1/8 inch collet or end mill holder. No specific OEM model compatibility was stated in the product data.

Installation Notes

This end mill is installed by machinists in a 1/8 inch collet, shrink-fit holder, or end mill chuck rated for the required runout tolerance. Ensure the spindle and holder are clean and free of debris before seating the shank to maintain concentricity at this diameter. At a 0.0200 inch cutting diameter, tool runout must be minimized to avoid breakage — verify runout with a dial indicator before beginning the cut. Feed rates and speeds should be set conservatively and validated against the workpiece material per standard machining practice.
