Keo 952-001-625 Side Milling Cutter 4 in 18T Hss

Product Description

The KEO 952-001-625 is a staggered-tooth side milling cutter designed for arbor-mounted milling operations on horizontal milling machines. It features a 4-inch cutter diameter and a 0.3125-inch cutting width, making it well suited for slotting, slabbing, and side-milling cuts where a narrow, precise kerf is required. Constructed from high speed steel with a bright uncoated finish, it delivers reliable performance across a range of workpiece materials. The staggered tooth configuration with a 10-degree helix angle and 10-degree radial rake reduces chatter and promotes smooth chip evacuation. Installation requires a 1-inch arbor hole. This cutter is used by machinist tradespeople in job shops, maintenance facilities, and production environments.

The 952-001-625 is appropriate for milling aluminum and other non-ferrous and ferrous workpiece materials, consistent with material application codes covering aluminum, cast iron, stainless steel, non-ferrous metals, steel, and heat-resistant superalloys. It is a solid choice for slotting and side-facing operations where a moderate tooth count of 18 provides a balance between chip load and surface finish. Typical installations involve mounting on a standard horizontal mill arbor with proper arbor support collars and a draw-in bolt to secure the cutter.

Key Features

• 4-inch cutter diameter with 0.3125-inch cutting width for precise narrow slots
• Staggered tooth design at 10-degree helix angle reduces vibration and chatter
• 10-degree radial rake angle promotes efficient chip removal
• High speed steel construction provides good toughness and re-sharpenability
• Bright uncoated finish suitable for general-purpose milling applications
• 18-tooth count balances chip load and finish quality

Compatibility

Designed for use on horizontal milling machines equipped with a 1-inch milling arbor. Suitable for milling aluminum, steel, stainless steel, cast iron, non-ferrous metals, and heat-resistant superalloys per the manufacturer material application designations.

Installation Notes

This cutter is installed and serviced by qualified machinists. Before mounting, ensure the milling machine is fully de-energized and the spindle is locked. Verify arbor diameter, arbor length, and support collar spacing before seating the cutter. Use appropriate personal protective equipment and follow shop safety protocols when handling sharp-edged cutting tools.
