Value Collection SC08181976 Arbor Spacer 3in 1in Id

Product Description

The VALUE COLLECTION SC08181976 is a hardened and ground alloy steel arbor spacer designed for use on milling machine arbors. With a 1-inch inside diameter and a 1-1/2-inch outside diameter, this spacer measures 3 inches thick and weighs approximately 0.78 pounds. It is manufactured from alloy steel and finished to a hardened and ground condition, providing consistent dimensional accuracy and resistance to wear under machining loads. This type of spacer is a standard component used by machinists and tool-and-die professionals to control cutter spacing and positioning on arbors.

This arbor spacer is suited for milling operations where precise cutter-to-cutter or cutter-to-shoulder spacing is required. The hardened and ground finish ensures flat, parallel faces that seat firmly against adjacent cutters or collars. It is a single-piece component packaged individually and appropriate for use in both production and toolroom environments where dimensional repeatability is critical.

Key Features

• Hardened and ground alloy steel construction for dimensional consistency and wear resistance
• 1-inch inside diameter fits standard milling machine arbors
• 1-1/2-inch outside diameter provides adequate contact surface for cutter and collar seating
• 3-inch thickness for controlling cutter spacing on longer arbor setups
• Flat, parallel ground faces for accurate and repeatable positioning

Compatibility

Designed for use with milling machine arbors requiring a 1-inch bore arbor spacer.

Installation Notes

Arbor spacers are installed by machinists during arbor assembly with the machine fully powered down and the spindle locked. Inspect spacer faces for nicks or burrs before installation, as surface defects will affect cutter runout and positioning accuracy. Follow the machine manufacturer's torque specifications for the arbor nut when securing cutters and spacers in place.
