Value Collection 934-000-266 Ball End Mill 0.0450 in 2 Flute Hss

Product Description

The VALUE COLLECTION 934-000-266 is a single-end ball end mill designed for precision milling operations across a wide range of metallic workpiece materials. Built from high speed steel (HSS) with a bright/uncoated finish, this tool measures 0.0450 inches in diameter with a 0.1350-inch length of cut and a 1.5000-inch overall length. The 2-flute, spiral-flute geometry features a variable helix angle of 35 to 40 degrees, supporting both roughing and finishing passes in a single tool. The center-cutting design allows plunge entry, making it suitable for slot milling, profiling, and contour work requiring a ball nose profile.

This end mill is appropriate for machining steel, stainless steel, cast iron, aluminum and non-ferrous alloys, high-temperature alloys, and hardened materials. Its compact 0.0450-inch diameter makes it well suited for fine-detail work, die and mold cavities, and intricate profiling passes on CNC machining centers or manual mills where a small-diameter ball nose is required. The straight-cylindrical shank diameter of 0.1875 inches (3/16 inches) fits standard collet and end mill holder systems at that bore size.

Key Features

• 0.0450-inch ball nose diameter with a 0.0225-inch nose radius for fine-detail profiling
• High speed steel construction rated for steel, stainless steel, cast iron, aluminum, high-temp alloys, and hardened materials
• Variable helix (35-40 degrees) reduces chatter and supports both roughing and finishing in a single pass
• Center-cutting design allows direct plunge entry without a pre-drilled hole
• Bright/uncoated finish suitable for general-purpose milling applications
• Right-hand cut and right-hand flute direction; Series 858 standard length

Compatibility

Designed as an OEM-style replacement or direct-use ball end mill compatible with standard collet systems and end mill holders sized for a 0.1875-inch (3/16-inch) straight-cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank fully into the collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as runout is especially critical at small diameters like 0.0450 inches.
