Accupro 14797393 Ball End Mill 0.035 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 14797393 is a miniature solid carbide ball end mill designed for high-precision milling operations in ferrous and hardened materials. With a 0.035-inch cutting diameter and four spiral flutes in a right-hand cutting, right-hand helix configuration, this end mill delivers clean, accurate cuts in tight geometries. The 30-degree helix angle promotes efficient chip evacuation and reduces heat buildup at the cutting edge. Applied AlTiN coating improves heat resistance and surface hardness, extending tool life in demanding applications. Micrograin carbide substrate provides the rigidity required at this diameter to maintain dimensional accuracy and resist deflection.

This end mill is suited for die and mold work, intricate contour milling, and detail work in aerospace, medical, and precision machining environments. At 0.035 inches in diameter with a 0.105-inch length of cut, it excels in fine-feature work where larger tooling cannot reach. The 1/8-inch shank diameter fits standard collet chucks commonly found on CNC machining centers and high-speed spindles. Single-end configuration means the tool is replaced rather than reversed when worn, which is standard for miniature end mills of this class.

Key Features

• 0.035-inch ball nose cutting diameter for fine-detail and micro-milling work
• AlTiN coating for elevated heat resistance and extended tool life in hard materials
• Micrograin solid carbide substrate for rigidity and resistance to edge chipping
• Four spiral flutes with 30-degree right-hand helix for efficient chip evacuation
• Single-end design with 1/8-inch shank for compatibility with standard collet systems
• Tight mill diameter tolerance of +0.0000 / -0.0010 inches for dimensional consistency

Compatibility

Designed as a miniature single-end ball end mill for use in CNC machining centers and high-speed milling spindles equipped with 1/8-inch collet or collet chuck toolholders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 1/8-inch shank fully into the collet to the recommended engagement depth before tightening to prevent runout. At this diameter, even minor runout or improper clamping can result in tool breakage or dimensional inaccuracy.
