Value Collection 934-000-236 Ball End Mill 0.0650 in 2 Flute

Product Description

The VALUE COLLECTION 934-000-236 is a cobalt ball end mill designed for precision milling of curved surfaces, contours, and complex 3D profiles. It features a 0.0650-inch mill diameter with a 0.0980-inch length of cut, a 0.0325-inch nose radius, and a variable helix angle of 35 to 40 degrees. The two-flute, single-end design suits both roughing and finishing passes in a wide range of metallic workpiece materials. The bright, uncoated cobalt construction delivers good thermal resistance and edge toughness without a surface coating, making regrinding straightforward. Machinists and tool-and-die professionals rely on this stub-length geometry for rigidity in tight-clearance setups.

This end mill is suited for machining steel, stainless steel, cast iron, aluminum and non-ferrous metals, high-temperature alloys, and hardened materials. Its stub-length configuration reduces deflection at small diameters, making it a practical choice for high-precision CNC milling centers and manual vertical mills where reach depth is limited and rigidity is critical. The straight-cylindrical shank diameter of 0.1875 inches fits standard collets and end mill holders used in production and prototype machining environments.

Key Features

• 0.0650-inch mill diameter with 0.0325-inch nose radius for fine contour and profile work
• Cobalt construction provides elevated heat resistance and edge durability compared to standard HSS
• Variable helix angle (35 to 40 degrees) reduces chatter and improves chip evacuation
• Centercutting geometry allows plunge entry into the workpiece
• Bright, uncoated finish simplifies regrinding and suits a broad range of cutting fluids
• Stub-length design maximizes rigidity at small diameters for tighter dimensional control

Compatibility

Designed as a direct-fit replacement for Series 857 stub-length cobalt ball end mills with a 0.1875-inch straight-cylindrical shank. Compatible with standard collet chucks, shrink-fit holders, and set-screw end mill holders accepting a 3/16-inch shank.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Confirm the collet or holder is clean and free of chips before seating the shank to the full recommended grip depth. Do not exceed the manufacturer-rated speeds and feeds for the workpiece material being cut.
