Keo 952-000-285 Side Milling Cutter 4in 1/4in Hss 24T

Product Description

The KEO 952-000-285 is a straight-tooth side milling cutter designed for horizontal milling operations on metalworking lathes and milling machines. Built from high speed steel with a bright, uncoated finish, it features a 4-inch cutter diameter, a 1/4-inch cutting width, and 24 teeth arranged in a straight tooth configuration with a 10-degree radial rake angle. The 1-1/4-inch arbor hole mounts directly to standard milling arbors. This cutter is suited for slotting, slabbing, and side milling cuts where a narrow kerf and clean shoulder finish are required. Machinists and tool-and-die professionals reach for this style of cutter when working ferrous and non-ferrous stock on manual or CNC horizontal mills.

The 952-000-285 fits typical shop applications including slot milling, gang milling setups, and straddle milling where consistent 0.25-inch width cuts are needed. Its uncoated HSS construction makes it straightforward to resharpen in-house, extending tool life beyond initial use. The straight tooth geometry produces lower cutting forces compared to helical alternatives, making it a practical choice on lighter-duty horizontal arbor setups or older Bridgeport-style milling machines adapted with an arbor support.

Key Features

• 4-inch cutter diameter with 1/4-inch (0.2500 inch) cutting width for precise narrow slots
• High speed steel construction - resharpenable and suited for a broad range of work materials
• Straight tooth configuration with 0-degree helix angle for lower axial cutting forces
• 10-degree radial rake angle promotes clean chip evacuation during side milling passes
• 24-tooth count provides fine finish on slot walls and side faces
• Bright, uncoated finish - no coating removal needed before regrinding
• 1-1/4-inch arbor hole fits standard milling machine arbors

Compatibility

Designed for use on horizontal milling machines accepting a 1-1/4-inch diameter arbor. Consult your machine arbor specifications and arbor support clearance before installation.

Installation Notes

Installation is performed by a qualified machinist. Power down and lock out the milling machine spindle before mounting or removing the cutter. Secure the cutter on the arbor with appropriate spacers and the arbor nut torqued per machine manufacturer guidelines, and confirm arbor support alignment before engaging a cut. Inspect the cutter for chipped or missing teeth prior to each use.
