Harvey Tool 857262 Square End Mill 1/16 in 3 Flute Carbide

Product Description

The HARVEY TOOL 857262 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 1/16 inch (0.0625 inch) cutting diameter and a 1/4 inch length of cut, this tool is built for small-feature work including slots, pockets, and profiling operations on a wide range of materials. The 42-degree variable helix geometry reduces harmonic vibration and chatter during the cut, improving surface finish and extending tool life. Three flutes provide a balance between chip evacuation and rigidity at this diameter. The bright, uncoated finish suits dry cutting and general-purpose machining. Machinists and CNC operators in job shops, tool rooms, and production environments rely on this style of end mill for detail work requiring high accuracy.

This end mill is suited for small-diameter milling operations in ferrous and non-ferrous materials where precision profiling and slotting are required. The 1/8 inch shank diameter fits standard ER collet chucks and toolholders common on vertical machining centers and CNC milling machines. The 2-1/2 inch overall length provides adequate clearance for most setups while maintaining stiffness at this small diameter. This is a single-end tool with right-hand cutting and right-hand flute direction, appropriate for conventional CNC milling operations.

Key Features

• Solid carbide construction for rigidity and wear resistance at small diameters
• 42-degree variable helix reduces chatter and improves surface finish
• 3-flute design balances chip clearance and core strength
• Right-hand cut, right-hand flute, single-end configuration
• Bright/uncoated finish for general-purpose and dry machining applications
• Non-centercutting geometry — not suited for direct plunge cutting

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 1/8 inch diameter ER collet chucks and compatible CNC milling toolholders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the minimum recommended engagement depth in the collet or toolholder — typically 3 times the shank diameter — and torque the collet nut per the toolholder manufacturer specification. Because this is a non-centercutting end mill, do not use direct axial plunge moves; use ramping or helical interpolation to enter the workpiece.
