Value Collection SC97305635 Rotary Tool Holder Bushing

Product Description

The VALUE COLLECTION SC97305635 is a Type B rotary tool holder bushing designed for use in drill jigs, fixture plates, and tooling setups where precise hole guidance and repeatable positioning are required. With a 5/16 inch (0.3125 inch) inside diameter and a 1-1/4 inch (1.2500 inch) outside diameter, this bushing accepts standard drill, reamer, and boring tool shanks of the corresponding size. The head thickness measures 0.265 inch, and the length under head is 2-1/8 inch (2.1250 inch), providing adequate support depth for most standard workholding applications. Machinists, tool and die makers, and fixture builders install this type of component during jig assembly or tooling maintenance.

This bushing is suited for machine shop environments, production tooling, and custom fixture fabrication in both small-batch and high-volume manufacturing settings. It is commonly installed in jig plates to guide cutting tools consistently from part to part, helping maintain positional accuracy across repeated operations. The Type B designation indicates a specific head and body geometry used in press-fit or slip-fit liner applications. It is sold individually, making it practical for maintenance replacement or low-quantity tooling builds.

Key Features

• Type B bushing geometry with a defined head for positive axial location in the jig plate
• Inside diameter of 5/16 inch (0.3125 inch) for compatible tool shank guidance
• Outside diameter of 1-1/4 inch (1.2500 inch) for standard liner or plate bore fitment
• Length under head of 2-1/8 inch (2.1250 inch) provides extended guidance for deep-hole drilling applications
• Head thickness of 0.265 inch supports seating stability against the jig plate surface
• Sold as a single unit, suitable for replacement or prototype tooling quantities

Compatibility

Designed as an OEM-style replacement or direct-fit component for rotary tool holder bushing applications requiring a Type B configuration with a 5/16 inch ID and 1-1/4 inch OD.

Installation Notes

Installation is typically performed by a machinist or tooling technician during fixture assembly or scheduled tooling maintenance. Ensure the receiving bore in the jig plate is clean, dimensionally correct, and free of burrs before pressing or sliding the bushing into position. Depower all machine spindles and confirm all cutting tools are retracted before servicing any jig or fixture component. Follow applicable shop safety standards and machine guarding requirements during installation.
