Accupro 33730789 Ball End Mill 1/32 in 2 Flute Carbide

Product Description

The ACCUPRO 33730789 is a solid carbide ball end mill designed for precision milling of contoured surfaces, cavities, and complex 3D profiles. Built with a 1/32 inch (0.0313 inch decimal) cutting diameter and a 0.0270 inch length of cut, this tool is engineered for fine detail work in hardened steels, alloys, and composites where dimensional accuracy is critical. The AlTiCrN coating provides thermal resistance and edge durability at elevated cutting speeds. With a 2-flute geometry and single-end configuration, it suits finish milling and light material removal in tight geometries. Machinists and CNC programmers working in tool and die, mold making, and aerospace component production will find this end mill suited to micro-scale contouring operations.

This end mill is used in vertical machining centers and CNC mills where small-diameter tooling is required. It is well suited for finish passes on hardened mold cavities, fine engraving details, and intricate profile work that demands minimal tool runout. The 1/8 inch shank diameter allows it to seat in standard collets and tool holders commonly found in high-speed machining setups. Its compact geometry makes it appropriate for residential prototype shops and commercial production floors alike.

Key Features

• 1/32 inch (0.0313 inch) ball cutting diameter for fine-detail and micro-scale milling
• AlTiCrN coating for high thermal resistance and extended tool life in ferrous and hard materials
• Solid carbide construction for rigidity and minimal deflection in small-diameter applications
• 2-flute design optimized for finish milling and contour passes
• 0.0930 inch neck length allows access to shallow pocketed features
• Single-end configuration with 1-1/2 inch overall length for standard tool holder compatibility

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and vertical mills accepting a 1/8 inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully powered down and at rest before changing tooling. Seat the 1/8 inch shank fully into the collet and torque the holder to the machine manufacturer's specification using the appropriate wrench. Verify runout with a dial indicator before beginning any cutting operation, as excessive runout at this diameter will accelerate tool wear and reduce surface finish quality.
