Accupro 14797345 Square End Mill 3/64 in 4 Flute Carbide

Product Description

The ACCUPRO 14797345 is a solid carbide square end mill designed for precision milling of ferrous and non-ferrous materials in machining centers and manual mills. The 3/64 inch (0.0469 inch) diameter cutting head features four flutes with a 30-degree helix angle and spiral flute geometry, producing clean edge profiles and efficient chip evacuation in tight-tolerance applications. At 0.07 inches length of cut and 1.5 inches overall length, this is a small-diameter tool built for fine detail work, slotting, and contouring where rigidity and edge sharpness are critical. The micrograin carbide substrate provides hardness and wear resistance suitable for high-speed operations.

This end mill is suited for production and job-shop environments where small-diameter, close-tolerance milling is required. The single-end configuration, right-hand cut, and right-hand flute direction make it compatible with conventional CNC machining center setups and manual knee mills. The 1/8 inch shank diameter fits standard collet systems commonly found in CNC routers, vertical machining centers, and tool-and-die operations. It is typically installed and used by machinists and CNC operators working on precision components, molds, dies, or prototype parts requiring fine feature geometry.

Key Features

• Solid micrograin carbide construction for improved hardness and edge retention
• Four-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Center-cutting capable, allowing plunge entry into workpiece material
• Bright/uncoated finish suitable for a broad range of general milling materials
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Mill diameter tolerance of +0.0000 / -0.0010 inch for consistent, repeatable cuts

Compatibility

Designed for use with standard 1/8 inch collet toolholders in CNC machining centers, CNC routers, and manual vertical mills. No specific model compatibility was stated in the product data.

Installation Notes

This tool is installed by machinists and CNC operators into a collet or end mill holder; ensure the collet bore matches the 1/8 inch shank diameter before mounting. Power down and lock out the spindle before inserting or removing the tool. Verify runout with a dial indicator after installation, as small-diameter carbide end mills are sensitive to even minor concentricity errors. Handle with care — carbide is brittle and can chip if dropped or impacted against hard surfaces.
