40 mm Hand Reamer Solid Long Pilot (King Pin / King Bolt)

Hand Reamer with Solid Long Pilot (King Pin / King Bolt)

Professional hand reamer with a solid long pilot designed for precision reaming of king pin and king bolt bushings in steering knuckles, suspension assemblies, and heavy-duty machinery. The extended pilot ensures accurate alignment of the cutting section, producing a straight, concentric bore with excellent surface finish.

What it actually does:

The reamer is used to finish newly installed bushings to their final internal diameter after pressing. The long pilot passes through the first bushing and guides the cutting section into the second, allowing both bushings to be machined accurately on the same centerline.

Solid Long Pilot Design

The solid extended pilot maintains precise alignment throughout the entire reaming operation. This design allows both bushings to be reamed on the same axis, ensuring proper king pin alignment, smooth movement, and reduced component wear.

Professional Reaming Process

Before reaming newly installed bushings, it is recommended to use steel sizing balls to properly seat and compress the bushings in their housing. This helps prevent bushing rotation during reaming and improves machining accuracy.

Precision Manufacturing

Each reamer is precision-ground to ensure excellent dimensional accuracy, smooth cutting action, and long service life. The accurately manufactured pilot and cutting edges provide stable guidance and consistent machining results.

Typical Applications

Suitable for reaming king pin and king bolt bushings in trucks, buses, construction equipment, agricultural machinery, trailers, forklifts, and other heavy-duty vehicles requiring accurate steering component alignment.
