Value Collection O-004 Tapered End Mill Hss 3 Flute

Product Description

The VALUE COLLECTION O-004 is a tapered end mill designed for precision milling operations where a controlled taper angle is required. Built from high speed steel, this tool features a 5-degree taper per side and a small end diameter of 1/16 inch, making it suited for narrow-profile cuts and die work. The square end geometry and three-flute spiral configuration support clean finishing passes in ferrous and non-ferrous materials. With a 1-inch length of cut and an overall length of 2-7/8 inches, the O-004 fits standard toolholders and milling machine spindles used in production and toolroom environments.

This tapered end mill is intended for use in vertical milling machines, CNC machining centers, and manual mills where angled wall features, tapered slots, or draft-angle profiles are required. The 3/8-inch shank diameter is compatible with common collet and end mill holder systems. It is a right-hand cut tool appropriate for conventional and climb milling setups. Machinists, toolmakers, and die-and-mold technicians are the primary users of this tool type in both job shop and production settings.

Key Features

• 5-degree taper per side for precise angled wall and draft-profile cuts
• Small end diameter of 1/16 inch for narrow entry and fine-detail milling
• High speed steel construction offers toughness across a range of work materials
• Three right-hand spiral flutes for efficient chip evacuation
• Square end geometry supports flat-bottom cuts and shoulder milling
• Centercutting design allows plunge entry without a pilot hole
• Uncoated finish for straightforward regrinding and reconditioning

Compatibility

Designed as an OEM-style replacement or standard toolroom end mill for use in milling machines and machining centers accepting a 3/8-inch shank diameter.

Installation Notes

Installation is performed by a machinist or toolroom technician using a collet chuck or end mill holder rated for the 3/8-inch shank. The machine spindle must be fully stopped and locked out before tool changes. Confirm runout with a dial indicator after seating the tool to ensure concentricity. Follow the machine manufacturer guidelines and applicable shop safety standards for speeds, feeds, and workholding when milling with tapered tooling.
