Accupro 12184490 Ball End Mill 1 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12184490 is a solid carbide ball end mill designed for precision milling operations in metal, composite, and engineering-grade material applications. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding cuts. The 1-inch diameter cutting profile, 2-inch length of cut, and 40-degree helix angle make it well-suited for profiling, contouring, and finishing passes where surface quality and dimensional accuracy are critical. Weighing 2 pounds, it is a single-end tool with a right-hand cutting and flute direction, sized for full-sized machining centers and CNC mills.

This end mill is intended for use in professional machine shop environments, CNC production floors, and tool rooms. The long-reach configuration, with a 6-inch overall length and 1-inch shank diameter, supports deep-cavity work and extended-reach applications where shorter tools cannot reach the workpiece geometry. The uncoated micrograin carbide substrate is appropriate for dry cutting or cutting with coolant on a range of ferrous and non-ferrous materials.

Key Features

• 1-inch ball nose diameter for contour profiling and 3D surface milling
• 2-inch length of cut for deep slot and cavity reach
• 3-flute spiral geometry with 40-degree helix angle for chip evacuation and finish quality
• Micrograin solid carbide construction for edge retention and rigidity
• Uncoated finish compatible with a wide range of cutting fluids and dry machining setups
• Single-end, right-hand cut with no chipbreaker for smooth finishing passes

Compatibility

Designed as a standard shank ball end mill for use in CNC machining centers and manual mills equipped with a 1-inch collet, end mill holder, or compatible tool holding system.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before mounting or removing any cutting tool. Seat the 1-inch shank fully into a clean, properly sized tool holder and torque the retention mechanism to the holder manufacturer specification. Verify runout with a dial indicator before production use to avoid premature edge wear or dimensional error.
