Value Collection SC08181745 Arbor Spacer 1in Id

Product Description

The VALUE COLLECTION SC08181745 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 measures 1-1/4 inches thick and provides precise positioning of cutters and collars along an arbor. The hardened and ground finish ensures dimensional accuracy and surface consistency critical to maintaining tool runout tolerances on the mill. This type of spacer is a standard consumable in machine shops and metalworking environments, typically sourced in sets to configure arbor tooling setups.

This arbor spacer is suited for horizontal and vertical milling operations where arbor-mounted cutters such as side milling cutters, shell end mills, or slitting saws require accurate axial positioning. It fits standard 1 inch bore milling machine arbors. Machinists use spacers like this to set cutter spacing, fill arbor length, and maintain rigid cutter support between support collars. The 1-1/4 inch thickness makes it appropriate for applications requiring a moderate spacer increment between tooling components.

Key Features

• 1 inch inside diameter fits standard milling machine arbors
• 1-1/2 inch outside diameter provides solid cutter support contact surface
• 1-1/4 inch thickness for precise axial cutter positioning
• Hardened and ground alloy steel construction for dimensional consistency and wear resistance
• Compatible with milling machine arbor setups requiring accurate spacer increments

Compatibility

Designed for use with milling machine arbors having a 1 inch bore diameter. Specific compatible machine or arbor models were not identified in the available product data.

Installation Notes

Arbor spacers are installed by machinists during arbor tooling setup on milling machines. Power down and de-energize the machine spindle before handling arbor components. Inspect the spacer bore and faces for burrs or debris before installation to avoid affecting cutter runout. Secure the arbor drawbar and support collar to the manufacturer specified torque using appropriate arbor tooling hardware.
