Value Collection 934-000-262 Ball End Mill 2 Flute Hss

Product Description

The Value Collection 934-000-262 is a single-end ball end mill designed for precision milling in metalworking and machining applications. It measures 0.0250 inches in diameter with a 0.0750-inch length of cut and a 0.1250-inch straight-cylindrical shank. The tool is manufactured from high speed steel (HSS) and carries a bright/uncoated finish. With a 2-flute, right-hand spiral configuration and a variable helix angle of 35 to 40 degrees, it is built for both roughing and finishing passes. Overall length is 1.5 inches. Centercutting geometry allows plunge entry. This end mill is suited for machinists and tool-and-die professionals working with close-tolerance, small-diameter applications.

The 934-000-262 is intended for use in CNC machining centers, manual mills, and tool room equipment where small-diameter ball nose profiles are required. It is rated for use across a broad range of workpiece materials including steel, stainless steel, cast iron, aluminum and non-ferrous metals, high-temperature alloys, and hardened materials. Its small diameter makes it well suited for fine detail work, engraving, contour milling, and die cavity finishing where larger tooling cannot reach.

Key Features

• 0.0250-inch mill diameter with a 0.0125-inch nose radius for precise ball-end profiling
• High speed steel construction supports a wide range of workpiece materials including hardened stock
• Variable helix (35 to 40 degrees) reduces chatter and improves surface finish
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Bright/uncoated finish; suitable for use with cutting fluids where required
• Right-hand cut, right-hand flute spiral; single-end configuration for standard toolholder setups
• Series 858 standard-length geometry; diameter tolerance of +0.0000 / -0.0010 inches

Compatibility

Designed as a standard-shank replacement end mill for use in any toolholder or collet accepting a 0.1250-inch straight-cylindrical shank, including ER collet chucks and precision end mill holders common in CNC and manual milling setups.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding guidelines. Ensure the spindle is fully powered down and locked before changing tooling. Seat the shank to the full recommended engagement depth in the collet or end mill holder to prevent pullout under cutting loads. At 0.0250 inches diameter, this tool is highly susceptible to breakage from excessive feed rate, runout, or improper clamping — verify collet condition and runout before use.
