Keo 952-001-669 Side Milling Cutter 4 in 18T Staggered Hss

Product Description

The KEO 952-001-669 is a staggered-tooth side milling cutter designed for slotting, slitting, and side milling operations on metalworking mills and arbor-driven setups. Built from high speed steel (HSS) with a bright uncoated finish, this cutter features a 4-inch cutter diameter, a 0.625-inch cutting width, and an 18-tooth staggered configuration with a 10-degree helix angle and a 10-degree radial rake angle. The staggered tooth layout reduces chatter and improves chip evacuation during cut. It mounts on a standard 1-1/4-inch arbor and is suited for horizontal and universal milling machine setups.

This cutter is optimized for milling aluminum and is a practical choice for job shops, tool rooms, and maintenance machining environments. The staggered tooth geometry distributes cutting forces across alternating teeth, helping maintain dimensional accuracy in slot and side-milling passes on non-ferrous workpieces. At 0.5 pounds, it is lightweight enough for easy arbor changes during production runs. Machinists working with arbor-type horizontal mills will find the 1-1/4-inch bore sizing consistent with standard tooling setups.

Key Features

• 4-inch cutter diameter for substantial depth-of-cut reach on horizontal mills
• 0.625-inch cutting width for precise slot and side milling passes
• 18 staggered teeth with 10-degree helix angle for reduced chatter and smoother cuts
• 10-degree radial rake angle optimized for aluminum milling
• High speed steel construction with bright uncoated finish
• 1-1/4-inch arbor hole fits standard horizontal milling arbors

Compatibility

Designed for use on horizontal and universal milling machines equipped with a standard 1-1/4-inch milling arbor. Optimized for aluminum material applications per manufacturer specification.

Installation Notes

Installation is performed by a qualified machinist. Power down and lock out the milling machine before mounting or removing the cutter from the arbor. Ensure the arbor spacers, collars, and arbor nut are properly torqued per the machine tool manufacturer's specifications before initiating a cut. Inspect the cutter teeth for chips or damage before each use and do not exceed the recommended RPM for the cutter diameter.
