Harvey Tool 84101 Saw Milling Arbor Straight Shank 3/8 Inch

Product Description

The HARVEY TOOL 84101 is a saw-style milling arbor designed to mount slitting saws, slotting cutters, and similar disc-type cutting tools onto straight-shank toolholders. The arbor features a 0.375-inch arbor diameter and a matching 0.375-inch straight shank diameter, giving the assembly a consistent through-diameter that simplifies setup in standard collet chucks or tool holders. Weighing approximately 0.09 pounds, this compact arbor is suited for precision milling operations where a low-profile, rigid connection between the spindle and the cutter is required. Machinists and toolroom operators working on CNC mills, manual knee mills, or similar machine tools will find this arbor a straightforward adapter for saw-blade-style cutters.

This arbor is intended for use in milling applications that require a slitting saw or side-milling cutter to be mounted on a straight-shank interface. Typical use cases include cutting narrow slots, parting operations, and undercutting on ferrous and non-ferrous workpieces. The straight shank design allows the arbor to seat directly in ER collets, end mill holders, or similar straight-bore toolholding systems commonly found in job shops and production machining environments.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully powered down and the tool is secured before mounting or removing the arbor. Verify that the collet or toolholder bore matches the 0.375-inch shank diameter and that all mating surfaces are clean and free of burrs before tightening. Follow the machine manufacturer and applicable shop safety guidelines when securing saw-type cutters to the arbor.
