Value Collection 934-000-229 Ball End Mill 0.03 in 2 Flute Cobalt

Product Description

The VALUE COLLECTION 934-000-229 is a cobalt ball end mill designed for precision milling operations across a wide range of workpiece materials. With a 0.0300-inch cutting diameter and a 0.0450-inch length of cut, this stub-length tool is built for tight-tolerance work in confined areas. The 2-flute, single-end design features a right-hand cut and right-hand spiral flute configuration with a variable helix angle of 35 to 40 degrees, which helps reduce chatter and improve surface finish. The bright, uncoated finish is suitable for use with or without coolant. This tool is used by machinists and CNC operators in job shops, tool rooms, and production environments.

This ball end mill is well suited for roughing and finishing operations on steel, stainless steel, cast iron, aluminum and non-ferrous materials, high-temp alloys, and hardened materials. The stub length format makes it a practical choice for short-reach applications where rigidity is critical, such as slotting, profiling, and contour milling at small scales. The 1/8-inch straight cylindrical shank fits standard collet systems common to CNC machining centers and manual mills.

Key Features

• Cobalt construction provides heat and wear resistance across a broad range of workpiece materials
• 0.0150-inch nose radius for true ball-end profile cuts and 3D contour work
• Variable helix angle (35 to 40 degrees) reduces harmonic vibration and improves chip evacuation
• Centercutting design allows plunge entry into the workpiece
• Bright/uncoated finish compatible with a wide range of cutting fluids and dry machining
• Series 857 stub-length format maximizes rigidity in short-reach setups

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills using a 1/8-inch collet or equivalent straight-cylindrical shank retention system. Suitable for primary workpiece material codes P, M, K, N, S, and H as classified in the input data.

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 shank fully into the collet to the recommended insertion depth and torque the collet nut per the collet manufacturer's specifications. Verify runout with a dial indicator before beginning the cut, as excessive runout on small-diameter end mills can cause premature tool failure or poor surface finish.
