Value Collection MT3290088 Square End Mill 1/4 in

Product Description

The VALUE COLLECTION MT3290088 is a solid carbide square end mill designed for precision milling operations in machine shop and production environments. With a 1/4 inch diameter and 2-flute spiral geometry at a 30-degree helix angle, this tool delivers efficient chip evacuation and clean cuts in a range of workpiece materials. The bright, uncoated finish makes it well-suited for applications where coating buildup or heat sensitivity is a concern. Centercutting capability allows plunge milling in addition to standard peripheral and slot milling. This end mill is a go-to choice for machinists and CNC operators working with tight tolerances on smaller-profile cuts.

This end mill is appropriate for use on vertical machining centers, CNC mills, and manual knee mills in both job shop and production settings. The 1/4 inch shank diameter fits standard collets and end mill holders without adaptation. The 3/4 inch length of cut and 2-1/2 inch overall length position this tool for shallow-to-moderate depth slotting, profiling, and contouring operations in aluminum, mild steel, plastics, and similar materials. It is sized for light to medium material removal where precision is the priority.

Key Features

• Solid carbide construction with submicron material grade for rigidity and wear resistance
• 2-flute spiral design with 30-degree right-hand helix for efficient chip evacuation
• Centercutting geometry allows plunge entry into workpiece material
• Bright/uncoated finish suitable for non-ferrous metals, plastics, and general-purpose milling
• Right-hand cutting direction, compatible with standard spindle rotation
• 1/4 inch shank fits common collet sizes without adapters

Compatibility

Designed for use in standard 1/4 inch collets and end mill holders on CNC machining centers, vertical mills, and compatible rotating spindle equipment.

Installation Notes

Installation and tool changes must be performed with the spindle fully stopped and the machine control in a safe state. Use a calibrated torque wrench and the appropriate collet nut wrench when seating the shank to avoid over-tightening or damaging the collet. Confirm runout with a dial indicator after tool setup before beginning a cut. Follow shop-standard speeds and feeds for the specific workpiece material and consult the machine manufacturer guidelines for maximum spindle RPM at this diameter.
