Value Collection SC05879002 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05879002 is a Type J rotary tool holder bushing designed for use in drill jigs and tooling fixtures where precise hole location and guided cutting tool support are required. With a 0.75 inch (3/4 inch) inside diameter and a 1 inch outside diameter, this bushing guides drill bits, reamers, or other rotary cutting tools with consistent alignment. The head thickness measures 0.265 inches and the length under the head is 1.75 inches, making it suited for applications requiring a moderate depth of engagement. Machinists and tool room technicians typically install and maintain these components.

Type J press-fit bushings are standard components in production drilling, jig boring, and repetitive-hole machining operations. They are used in both job shop and manufacturing environments where drill jig fixtures must maintain tight positional tolerances across multiple workpieces. This bushing is appropriate for moderate-duty machining setups in metalworking and fabrication applications where repeatable hole location is critical.

Key Features

• Type J bushing configuration with a flanged head for positive axial positioning in jig plates
• 0.75 inch inside diameter for compatibility with corresponding drill or reamer shank sizes
• 1 inch outside diameter for press-fit installation into standard jig bushing bores
• 1.75 inch length under head provides adequate tool guidance depth for typical workpiece thicknesses
• 0.265 inch head thickness with a 7/8 inch distance between hole centers for fixture layout reference

Compatibility

Designed as a standard Type J rotary tool holder bushing for use in drill jig fixtures requiring a 0.75 inch inside diameter and 1 inch outside diameter press-fit installation.

Installation Notes

Installation of press-fit jig bushings is typically performed by a machinist or toolmaker using an arbor press or hydraulic press to achieve proper seating without damage to the bushing or jig plate bore. Ensure the receiving bore is clean, properly sized, and free of burrs before pressing the bushing into place. Do not hammer the bushing directly, as this may distort the inside diameter and compromise tool guidance accuracy. Follow applicable shop standards and fixture design specifications for interference fit tolerances.
