Boneham CB00001106 Press Fit Headless Drill Bushing

Product Description

The BONEHAM CB00001106 is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Assigned industry code P, this bushing features an inside diameter of 0.238 inches with a tight tolerance of +0.0001 to +0.0004 inches, ensuring repeatable hole location accuracy. The body outside diameter is 13/32 inches and the overall length is 1 inch. Constructed from steel, it is pressed directly into a jig plate without a locking head, keeping the top surface flush. Machinists, tool-and-die makers, and production drilling setups rely on this type of bushing for consistent drill guidance across high-volume operations.

This bushing is suited for fixed jig applications where the bushing remains permanently installed in the drill plate. Its headless design makes it appropriate for setups where a flush or recessed installation is required and where tool clearance above the plate is limited. It is not a renewable bushing, meaning it is intended for permanent press-in installation rather than quick-change replacement. Typical use is in production machining environments, toolrooms, and fixture fabrication shops.

Installation Notes

Press fit bushings are installed by machinists or toolmakers using an arbor press to drive the bushing into a precision-reamed hole in the jig plate. Ensure the receiving hole in the plate is reamed to the appropriate press fit tolerance before installation. Once pressed in, this bushing is not intended for removal or replacement. Always secure workpieces and fixtures properly before beginning drilling operations.
