Harvey Tool 919545 Tapered End Mill 3 Flute Carbide Square

Product Description

The HARVEY TOOL 919545 is a solid carbide tapered end mill designed for precision milling in tight geometries and miniature part applications. It features a 15-degree taper angle per side, three flutes, and a square end configuration. The small end diameter measures 0.045 inches, making it well suited for fine detail work where cutting-edge accuracy is critical. With a 30-degree helix angle, the tool promotes efficient chip evacuation and smooth cutting action. This end mill ships uncoated and is ready for use in standard machining centers operated by machinists and tooling specialists.

This end mill belongs to the Harvey Tool Miniature End Mills - Tapered - Square series, built for small-scale milling operations in industries such as medical device manufacturing, aerospace component production, mold and die work, and precision instrument fabrication. It is appropriate for use in CNC machining centers where fine taper geometry and tight tolerance control are required. Its compact dimensions make it a practical choice for slotting, profiling, and light pocketing in confined workspaces.

Key Features

• 15-degree taper angle per side for consistent draft geometry in tapered slots and cavities
• Three-flute solid carbide construction for rigidity and wear resistance
• Small end diameter of 0.045 inches for fine detail and miniature feature milling
• 30-degree helix angle promotes efficient chip flow and reduced cutting forces
• Square end configuration for flat-bottom cuts and sharp corner definition
• Uncoated finish suitable for use as-is or as a base for operator-applied coatings

Compatibility

Designed as an OEM-style replacement and standard tooling option within the Harvey Tool Miniature End Mills - Tapered - Square series for use in CNC machining centers accepting a 3/16-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop-standard tool-change procedures. Ensure the spindle is fully stopped and locked before inserting or removing any end mill. Confirm the collet or tool holder is rated for the 3/16-inch shank diameter and properly torqued per the machine tool manufacturer specifications. Inspect the cutting edges for chips or damage before each use, as carbide tooling is brittle and sensitive to improper handling or interrupted cuts.
