Value Collection MT3290807 Square End Mill 11/16 in 4 Flute

Product Description

The VALUE COLLECTION MT3290807 is a 4-flute solid carbide square end mill designed for precision milling operations in metal fabrication, tool-and-die, and general machining applications. It features an 11/16 inch (0.6875 inch) cutting diameter, a 1-1/2 inch length of cut, and a 30-degree helix angle. Constructed from submicron-grade solid carbide, this end mill delivers rigidity and wear resistance in demanding cutting environments. The bright/uncoated finish makes it well-suited for non-ferrous metals, plastics, and certain ferrous materials where coating is not required. Machinists and CNC operators rely on this geometry for slotting, profiling, and peripheral milling work.

This end mill is intended for use in vertical machining centers, CNC milling machines, and manual knee mills with a compatible 3/4 inch tool holder or collet. The centercutting design allows direct plunge entry into the workpiece without a pre-drilled pilot hole, adding flexibility in multi-operation setups. Right-hand cutting and right-hand flute direction are standard for conventional spindle rotation. It is appropriate for both roughing and finishing passes depending on feeds, speeds, and material selection.

Key Features

• Submicron-grade solid carbide construction for rigidity and extended tool life
• 4-flute spiral geometry supports efficient chip evacuation and smooth surface finish
• 30-degree helix angle balances cutting forces across a range of materials
• Centercutting capability allows direct plunge milling without a pilot hole
• Bright/uncoated finish suitable for non-ferrous metals and plastics
• Right-hand cut and right-hand flute direction for standard CNC and manual mill spindles

Compatibility

Designed as a standard-geometry square end mill for use in any milling machine or machining center with a 3/4 inch collet or end mill holder and right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully into a 3/4 inch collet or end mill holder to the manufacturer-recommended engagement depth before tightening. Power down and lock out the machine spindle before changing tooling. Verify runout with a dial indicator after seating to prevent premature tool wear or workpiece damage.
