Harvey Tool 996299 Tapered End Mill 1/8 Inch 3 Flute Carbide

Product Description

The HARVEY TOOL 996299 is a solid carbide tapered end mill designed for high-precision milling operations requiring a controlled taper profile. It features a 4-degree taper angle per side with a 1/8 inch small end diameter, making it well suited for narrow-slot work, draft-angle milling, and intricate 3D contouring. The 3-flute geometry with a 30-degree helix angle supports efficient chip evacuation and smooth cutting action in a variety of materials. With a 1-1/4 inch length of cut and a 3/8 inch shank diameter, this tool provides rigidity through the full depth of engagement. It ships uncoated and is part of the Miniature End Mills - Tapered - Square series.

This end mill is used in CNC machining centers and manual mills where tapered walls or draft angles are required. It is a common choice for mold and die work, aerospace component machining, and precision part manufacturing. The miniature form factor and square end make it appropriate for finishing passes in tight geometries where a standard straight end mill cannot produce the required wall angle. Machinists and tooling specialists working in job shops, production facilities, and prototype environments will find this tool applicable to a wide range of ferrous and non-ferrous workpiece materials.

Key Features

• 4-degree taper angle per side for controlled draft-wall profiles
• 1/8 inch small end diameter for narrow-slot and fine-detail work
• 3 flutes with 30-degree helix angle for efficient chip evacuation
• 1-1/4 inch length of cut supports full-depth tapered passes
• Solid carbide construction for rigidity and wear resistance
• Square end geometry delivers flat-bottom and sharp-corner finishes
• Uncoated surface finish for use across a broad range of base materials

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and milling machines accepting a 3/8 inch straight shank, within the Miniature End Mills - Tapered - Square series.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the 3/8 inch shank in a compatible collet or end mill holder torqued to the machine manufacturer's specification. Verify runout after installation and confirm programmed taper angle and depth-of-cut values match the tool geometry before running the first pass.
