Value Collection SC08183246 Arbor Spacer 1.5 in Id

Product Description

The VALUE COLLECTION SC08183246 is a hardened and ground alloy steel arbor spacer designed for use with milling machine arbors. It features a 1-1/2 inch inner diameter, a 2-1/8 inch outer diameter, and a 3/8 inch thickness. The hardened and ground finish ensures close tolerances and consistent face-to-face contact, making it suitable for precise cutter positioning on horizontal or vertical milling setups. Machinists and tool room technicians install these spacers to control cutter spacing and maintain accurate tool location along an arbor shaft. The part weighs 0.18 pounds.

This arbor spacer is intended for use with standard milling machine arbors in machine shop and tool room environments. It is well suited for horizontal milling operations where multiple cutters or spacers are stacked to achieve a specific cutter spread. The hardened alloy steel construction holds up to the clamping loads and vibration typical of production milling work.

Key Features

• 1-1/2 inch inner diameter fits standard milling arbor shanks
• 2-1/8 inch outer diameter provides adequate bearing surface for cutter spacing
• 3/8 inch thickness for precise axial positioning of milling cutters
• Hardened and ground alloy steel construction for tight tolerances and long service life
• Lightweight at 0.18 pounds — easy to handle and stack with other spacers

Compatibility

Designed for use with milling machine arbors. Verify inner diameter, outer diameter, and thickness against arbor and cutter specifications before installation.

Installation Notes

A qualified machinist or tool room technician should install arbor spacers. Power down and lock out the milling machine before mounting or removing any arbor hardware. Inspect spacer faces for burrs or contamination and clean mating surfaces before assembly to ensure proper seating. Do not use damaged or out-of-tolerance spacers, as improper fit can affect cutter runout and machine safety.
