Value Collection 934-000-041 Ball End Mill 9/64 in 2 Flute Cobalt

Product Description

The VALUE COLLECTION 934-000-041 is a double-end, two-flute cobalt ball end mill designed for milling operations requiring both roughing and finishing passes in a single tool. Manufactured from M42 cobalt high-speed steel, this end mill delivers heat resistance and edge retention when cutting ferrous and difficult-to-machine materials. The mill diameter measures 9/64 inches (0.1406 inches) with a 7/32-inch (0.2187-inch) length of cut and a 3/16-inch (0.1875-inch) straight-cylindrical shank. The bright, uncoated finish and variable helix angle between 35 and 40 degrees reduce chatter and promote clean chip evacuation across a range of workpiece materials. The double-end configuration maximizes tool life per unit.

This end mill is suited for small-diameter milling work in job shops, tool rooms, and production environments. The stub-length body keeps deflection low during tight-tolerance operations. Centercutting geometry allows plunge entry without a pre-drilled pilot hole. Primary workpiece materials include steel, stainless steel, cast iron, aluminum and non-ferrous alloys, high-temperature alloys, and hardened materials, making this tool a versatile choice for machinists working across ISO material groups P, M, K, N, S, and H.

Key Features

• M42 cobalt construction for heat resistance and extended edge life in hard and abrasive materials
• Variable helix angle (35-40 degrees) reduces harmonic vibration and improves surface finish
• Double-end design provides two usable cutting ends, extending tool life
• Centercutting capable — supports direct plunge milling without pilot hole
• Bright/uncoated finish compatible with a wide range of cutting fluids and dry cutting applications
• Rated for roughing and finishing material removal in a single tool

Compatibility

Designed as an OEM-style replacement and standard-production ball end mill for use in CNC machining centers, knee mills, and manual milling machines accepting a 3/16-inch straight-cylindrical shank. Compatible with primary workpiece materials: steel, stainless steel, cast iron, aluminum and non-ferrous alloys, high-temperature alloys, and hardened materials.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully within the collet or end mill holder and torque to the machine manufacturer's specified clamping requirement before operation. Verify spindle direction is set to right-hand rotation to match the right-hand cutting and flute direction of this tool. Inspect the cutting edges for chips or damage before each use, and replace the tool at the first sign of edge deterioration to maintain dimensional accuracy and prevent workpiece damage.
