Value Collection SC08181489 Arbor Spacer 1in Id X 1.5in Od

Product Description

The VALUE COLLECTION SC08181489 is a hardened and ground alloy steel arbor spacer designed for use with milling machine arbors. With a 1 inch inside diameter and a 1-1/2 inch outside diameter, this spacer provides precise positioning and spacing of cutters, collars, and other tooling components along a milling arbor. At 3/4 inch thick, it maintains consistent stack height and helps reduce tool deflection during cutting operations. Machined from alloy steel and finished to a hardened and ground standard, it delivers the dimensional accuracy and surface finish that machine tool setups demand. Weighing 0.31 pounds, it is a lightweight but durable component for the machine shop environment.

This arbor spacer is suited for horizontal and vertical milling machine setups where precise cutter spacing is required. It is commonly used by machinists and tool room technicians to position milling cutters, side-milling cutters, and form cutters at specific intervals along a standard milling arbor. The hardened and ground finish ensures flatness and parallelism between mating surfaces, which is critical for maintaining cutter runout tolerances in precision machining applications.

Key Features

• Hardened and ground alloy steel construction for dimensional accuracy and durability
• 1 inch inside diameter for standard milling arbor fitment
• 1-1/2 inch outside diameter provides adequate bearing surface for cutter and collar contact
• 3/4 inch thickness for precise cutter spacing along the arbor
• Flat and parallel ground faces support accurate cutter positioning and minimize runout

Compatibility

Designed for use with milling machine arbors requiring a 1 inch bore arbor spacer. Consult your machine tool documentation to confirm arbor diameter and spacer stack requirements before installation.

Installation Notes

Arbor spacers are installed by qualified machinists during milling arbor setup. Power down and lock out the milling machine before assembling or disassembling any arbor components. Ensure all mating surfaces are clean and free of burrs or debris before stacking spacers, as contamination between faces can introduce cutter runout. Follow the machine manufacturer's arbor nut torque procedures and use appropriate draw-in bar or arbor nut tooling for final tightening.
