Accupro 14797418 Ball End Mill 0.09 in 2 Flute Carbide

Product Description

The ACCUPRO 14797418 is a solid carbide ball end mill designed for high-precision milling in tight-tolerance applications. With a 0.09 inch cutting diameter and a 0.135 inch length of cut, this miniature-series tool is built for detailed profiling, contouring, and slotting passes in hard and abrasive workpiece materials. The AlTiN coating provides elevated heat resistance and extended tool life when cutting ferrous alloys, hardened steels, and similar demanding materials. The 2-flute geometry promotes efficient chip evacuation in small-diameter toolpaths. This end mill is used by machinists and tool-and-die professionals working on CNC machining centers and high-speed milling setups.

This miniature ball end mill is suited for precision work in mold making, die sinking, and small-part machining where a tight diameter tolerance and consistent geometry are required. The 1/8 inch shank diameter fits standard collet chucks used on CNC vertical machining centers and high-speed spindles. The 30-degree helix angle and right-hand flute and cutting direction make it compatible with conventional CNC climb-milling routines on small-feature geometry. It is a single-end tool intended for dedicated finishing and semi-finishing passes rather than heavy roughing.

Key Features

• 0.09 inch ball cutting diameter with a mill diameter tolerance of +0.0000 to -0.0010 inches for consistent part accuracy
• AlTiN coating for improved heat resistance and extended tool life in ferrous and hardened materials
• Solid carbide micrograin substrate for rigidity and edge sharpness in small-diameter tooling
• 2-flute spiral geometry with 30-degree helix angle for efficient chip evacuation
• Right-hand cut, right-hand flute, single-end configuration for standard CNC milling setups
• 1/8 inch shank diameter with a shank tolerance of -0.0001 to -0.0003 inches for secure collet grip

Compatibility

Designed as an OEM-style miniature ball end mill for use in standard 1/8 inch collet chucks on CNC machining centers and high-speed milling spindles suited to small-diameter carbide tooling.

Installation Notes

Installation and use of this end mill should be performed by a qualified machinist or CNC operator. Ensure the spindle and collet are clean and within tolerance before seating the 1/8 inch shank to maintain runout specifications. Verify programmed feeds and speeds are appropriate for the 0.09 inch diameter and workpiece material before initiating a cut. Do not exceed the tool length of cut with axial depth-of-cut values that would engage the shank shoulder.
