Accupro 14899846 Square End Mill 0.09in 4 Flute Carbide

Product Description

The ACCUPRO 14899846 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.09 inch cutting diameter and four right-hand spiral flutes at a 30-degree helix angle, this tool delivers clean, accurate cuts in demanding materials. The micrograin carbide construction provides the rigidity and edge retention required for tight-tolerance work. Extended reach geometry and a bright uncoated finish make it well-suited for light-duty slotting, profiling, and contouring operations where coating buildup is a concern. Machining professionals and tool crib operators select this end mill for small-diameter work on CNC mills and machining centers.

This end mill fits residential shop and industrial CNC machining environments where small-diameter precision cutting is required. The 0.09 inch diameter and 17/64 inch length of cut make it appropriate for fine detail milling, micro-slot cutting, and intricate contouring on ferrous and non-ferrous materials. The 1/8 inch shank diameter is compatible with standard collet systems found on vertical mills and CNC machining centers. The single-end, centercutting design allows plunge entry as well as peripheral cutting.

Key Features

• 0.09 inch cutting diameter with mill diameter tolerance of +0.0000 / -0.0010 inches for precise fits
• Four right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation
• Micrograin solid carbide construction for rigidity and extended edge life
• Centercutting geometry allows direct plunge entry without pre-drilling
• Extended reach design with 0.625 inch reach length for deeper cavity access
• Bright uncoated finish suitable for applications where coated tools are not required

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC vertical mills and machining centers using 1/8 inch collet systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician familiar with collet torque procedures and runout verification. Confirm the collet and spindle are clean and free of chips before seating the shank. Secure the end mill to the manufacturer-recommended collet pull-out torque specification for 1/8 inch shanks per machine builder guidelines. Verify runout with a dial indicator before beginning production cuts to protect the tool and workpiece.
