Accupro 14797240 Square End Mill 1/16 in 3 Flute Carbide

Product Description

The ACCUPRO 14797240 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. With a 0.0625 inch (1/16 inch) mill diameter and a 3-flute, spiral-flute geometry at a 30-degree helix angle, this end mill delivers efficient chip evacuation and smooth cutting action in tight-tolerance applications. The micrograin carbide construction provides the rigidity and wear resistance required for small-diameter work. It is center-cutting, allowing plunge entry, and features right-hand cut and right-hand flute direction. Machinists and toolmakers handling fine detail work, micro-milling, or small-part production will find this tool suited to demanding shop environments.

This end mill is built for single-end use in CNC machining centers, knee mills, and manual milling setups where small-diameter precision cutting is required. The extended reach design, with a neck length of 1.125 inches and a reach length of 0.95 inches, enables access to deeper features without sacrificing rigidity at the cutting edge. The 1/8 inch shank diameter is standard for small toolholders and collet systems commonly used in high-speed spindle applications. No coolant-through capability is present, so flood or mist coolant applied externally is appropriate for heat management during extended cuts.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in small-diameter milling
• 3-flute spiral geometry with 30-degree helix angle for efficient chip evacuation
• Center-cutting design allows direct plunge entry without pre-drilling
• Extended reach with 1.125 inch neck length for access to deeper part features
• Bright/uncoated finish suitable for non-ferrous metals, plastics, and general-purpose applications
• Right-hand cut and right-hand flute direction for standard CNC and manual mill setups

Compatibility

Designed as a single-end square end mill compatible with 1/8 inch collets, end mill holders, and toolholding systems accepting a 0.125 inch shank diameter. Part of the ACCUPRO ASQSC3-CCER series.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Insert the shank to the recommended engagement depth in the collet or holder and torque the drawbar or collet nut per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning production cuts, as runout is critical at this diameter.
