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

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

Professional 25 mm hand reamer with a solid long pilot designed for precision reaming of king pin and king bolt bushings in steering knuckles, suspension components, and heavy-duty machinery. The extended pilot keeps the tool aligned with the original bore, ensuring excellent concentricity and a smooth, accurate finish.

What it actually does:

This hand reamer is specifically designed for sizing newly installed king pin bushings to their final diameter. The long solid pilot guides the tool through both bushings, allowing them to be machined accurately on the same centerline. This improves alignment, reduces friction, and ensures proper king pin fitment.

Solid Long Pilot Design

The extended pilot passes through both bushings before the cutting edges engage, keeping the reamer perfectly aligned during the operation. This design allows both bushings to be reamed on the same axis, resulting in superior concentricity and smooth king pin installation.

Important Installation Recommendation

Before reaming newly installed bushings, it is recommended to use steel sizing balls to seat and compress the bushings into their housing. This helps prevent the bushings from rotating during the reaming process and improves dimensional accuracy.

Precision Manufacturing

Each reamer is manufactured with precision-ground cutting edges and accurately controlled guide dimensions to ensure smooth cutting, excellent bore finish, and long tool life when used with appropriate cutting oil.

Typical Applications

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