45-50 HSS Adjustable Hand Reamers solid Long Pilot (King Pin / King Bolt)

45–50 HSS Adjustable Hand Reamers – Solid Long Pilot (King Pin / King Bolt)

Professional-grade adjustable hand reamers designed for accurate alignment and finishing of king bolt and king pin bushings, bearings, and precision assemblies requiring perfectly coaxial holes. The integrated solid long pilot ensures stable guidance through multiple bores, allowing precise reaming when two or more holes must remain mechanically aligned on the same axis.

The floating tapered guide sleeve enables self-centering in the opposite bore during operation, improving accuracy and reducing the risk of misalignment. Manufactured with high-performance HSS 18% blade steel hardened to HRc 64-67, these reamers deliver excellent wear resistance, edge retention, and long service life even in demanding workshop environments.
