L&I 533.3055 Tapered Fluted Chucking Reamer

This is a new L&I (Winooski, VT) tapered fluted reamer, part number 533.3055. The tool features a multi-flute tapered body — visible in the photos as a long, gradually tapering shank with longitudinal flutes ground along the body — and a through-hole at the butt end consistent with a chucking or machine reamer design. L&I (Laroche & Iodice or similar Vermont precision tooling house) produced specialty reamers and precision tooling for industrial and defense applications; the part number 533.3055 follows an internal L&I catalog convention and does not directly decode to a standard industry taper (such as Morse or Brown & Sharpe) without the original catalog, so buyers should measure the small and large diameter and overall length to confirm fitment before ordering. The tool appears uncoated bright HSS or carbide-tipped construction based on the silver finish, with no visible wear, making it suitable for precision hole finishing in metal or composite materials on a machine tool.
