Harvey Tool 827516 Square End Mill 1/4 in 2 Flute Carbide

Product Description

The HARVEY TOOL 827516 is a solid carbide square end mill designed for precision milling operations in metal, wood, composite, and plastic materials. With a 1/4 inch cutter diameter and a 1 inch length of cut, this single-end tool delivers clean, square-shouldered cuts in a compact form factor. The 2-flute downcut geometry is engineered to push chips downward, reducing surface tearout and producing a cleaner top-edge finish. A 20-degree helix angle supports smooth chip evacuation and stable cutting. This tool ships uncoated in a bright finish and is installed by machinists and CNC operators across job shop, production, and tool room environments.

This end mill is well suited for slotting, profiling, and pocketing operations where a downcut flute geometry is required to control surface quality on the top face of the workpiece. It is a strong choice for operations on laminates, veneers, plastics, and soft metals where upward chip throw would cause delamination or edge damage. The 1/4 inch shank diameter fits standard ER collet systems, end mill holders, and router chucks commonly used in CNC machining centers and manual knee mills. The 3 inch overall length provides adequate reach for most standard fixturing setups.

Key Features

• Downcut flute geometry drives chips toward the workpiece surface, minimizing tearout on the top edge
• Solid carbide construction provides rigidity and wear resistance over high-speed steel alternatives
• 1/4 inch cutter diameter and 1/4 inch shank diameter for direct collet or end mill holder fitment
• 1 inch length of cut supports slotting and pocketing at full depth without excessive overhang
• 20-degree helix angle balances chip evacuation with cutting stability
• Bright/uncoated finish suitable for use with or without cutting fluid across a range of workpiece materials

Compatibility

Designed as a direct-fit replacement for 1/4 inch shank square end mill applications using standard ER collet chucks, end mill holders, or compatible router-style tooling systems.

Installation Notes

Installation is performed by machinists and CNC setup technicians. Always power down and lock out the spindle before changing tooling. Ensure the collet or holder bore is clean and free of chips before seating the shank. Verify runout with a dial indicator after tool engagement before beginning a cut to avoid premature tool wear or workpiece damage.
