Value Collection W-202 Tapered End Mill 3 Flute Hss

Product Description

The VALUE COLLECTION W-202 is a tapered end mill designed for precision milling operations where a controlled taper profile is required. Built from high speed steel (HSS), it features a 20-degree taper angle per side and a 1/8 inch small end diameter, making it well suited for creating tapered slots, draft angles, and contoured surfaces in a variety of workpiece materials. The square end geometry allows for flat-bottom cuts, and the three-flute spiral configuration balances chip evacuation with surface finish quality. This tool is center-cutting, allowing direct plunge entry into the workpiece.

The W-202 is used in vertical milling machines and CNC machining centers for light-to-medium material removal in ferrous and non-ferrous metals, plastics, and composites. The 3/8 inch shank diameter fits standard ER and straight-bore collet systems commonly found in production and job-shop environments. With a 1/2 inch length of cut and 2-1/2 inch overall length, it is suited for shallow-to-moderate depth tapered features in both prototype and production runs. Machinists and toolroom operators are the primary users of this end mill type.

Key Features

• 20-degree taper angle per side for consistent draft and taper profiles
• High speed steel construction provides toughness and re-sharpenability
• Square end geometry produces flat-bottomed tapered cuts
• Three right-hand spiral flutes for efficient chip removal and balanced cutting forces
• Center-cutting design allows direct plunge milling without pre-drilling
• Bright/uncoated finish suitable for use with standard cutting fluids

Compatibility

Designed as a standard tapered end mill for use in vertical mills and CNC machining centers equipped with a 3/8 inch collet or tool holder capable of accepting straight-shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Secure the 3/8 inch shank firmly in the collet to the manufacturer-specified pull-out resistance per shop practice. Verify runout with a dial indicator before beginning the cut, as excessive runout accelerates wear and reduces dimensional accuracy on tapered features.
