Value Collection SC99109092 Tool Holder Bushing Type B

Product Description

The VALUE COLLECTION SC99109092 is a Type B rotary tool holder bushing designed for use in drill jigs and tooling fixtures. It features a 3/16-inch (0.1875 inch) inside diameter, a 1-inch (1.0000 inch) outside diameter, and a length under head of 1-3/4 inches (1.7500 inches). The head thickness measures 0.265 inches. This bushing serves as a precision guide for drill bits, reamers, and other rotary cutting tools, maintaining accurate hole location and reducing tool wander during machining operations. It is typically installed by machinists, toolmakers, and maintenance technicians working with jig and fixture setups.

This Type B press-fit style bushing is suited for production drilling and repetitive hole-location applications in manufacturing and machine shop environments. It seats into a mating liner bushing or directly into a jig plate, providing a renewable wear surface for drill guidance. Typical applications include general metalworking, fabrication fixtures, and maintenance tooling setups where consistent hole placement is critical.

Key Features

• Type B configuration with a 0.265-inch head thickness for positive seating against the jig plate face
• Inside diameter of 0.1875 inches guides 3/16-inch tooling with close tolerances
• Outside diameter of 1.0000 inch for standard liner bushing or jig plate fitment
• Length under head of 1.7500 inches accommodates workpiece thickness and chip clearance requirements
• Renewable wear component that can be replaced without reworking the jig plate

Compatibility

Designed as an OEM-style replacement or standard tooling component for drill jig fixtures requiring a Type B press-fit bushing with a 3/16-inch bore and 1-inch outside diameter.

Installation Notes

Installation is typically performed by a machinist or toolmaker using an arbor press to seat the bushing flush or to the designed depth in the liner or jig plate. Power down and secure all machinery before installing or removing bushings from active fixtures. Do not hammer the bushing directly without a proper driver to avoid distorting the bore. Verify bore alignment and fit class before pressing to final depth.
