Value Collection 934-000-270 Ball End Mill 2 Flute Hss

Product Description

The VALUE COLLECTION 934-000-270 is a single-end ball end mill designed for precision milling operations across a wide range of metalworking applications. Built from high speed steel (HSS), it features a 0.0650-inch mill diameter, a 0.1950-inch length of cut, and a 1.5000-inch overall length. The two-flute spiral configuration with a variable helix angle of 35 to 40 degrees supports both roughing and finishing passes. The bright/uncoated finish and right-hand cutting direction make this a straightforward, general-purpose tool suited for machinists and toolroom technicians working on tight-tolerance features.

This end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills where small-diameter ball-nose toolpaths are required. It is rated for use on steel, stainless steel, cast iron, aluminum and non-ferrous materials, high-temperature alloys, and hardened materials. The 3/16-inch straight-cylindrical shank fits standard collets and tool holders in that bore size. Series 858 standard-length geometry suits typical cavity, contour, and radius milling tasks where reach is not a limiting factor.

Key Features

• 0.0650-inch ball nose diameter with a 0.0325-inch nose radius for tight-radius contouring
• High speed steel construction rated for steel, stainless steel, cast iron, aluminum, high-temp alloys, and hardened materials
• Variable helix angle (35 to 40 degrees) reduces chatter and supports both roughing and finishing in a single tool
• Center-cutting design allows plunge entry into the workpiece
• Bright/uncoated finish provides consistent performance without coating build-up concerns on non-ferrous materials
• Right-hand cut and right-hand flute spiral for use in standard spindle configurations

Compatibility

Designed as a standard-fitment replacement or addition for 3/16-inch straight-shank collet systems on CNC and manual milling machines. Compatible workpiece materials include steel, stainless steel, cast iron, aluminum and non-ferrous alloys, high-temperature alloys, and hardened materials as rated by the manufacturer.

Installation Notes

Installation is performed by a machinist or toolroom technician using a compatible collet or end mill holder sized for a 3/16-inch shank. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Seat the shank fully into the holder to the recommended gauge-line depth and torque the collet nut per the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, particularly at this small diameter where even minor runout can affect tool life and surface finish.
