Description

Drillco 427A224-132 1-3/8 Spiral Flute 1/2 Shank Construction Reamer is engineered for heavy-duty reaming in structural steel fabrication, bridge construction, and other demanding assembly applications. Its tapered point allows smooth entry into misaligned or undersized holes, ensuring precise alignment of components during installation. The spiral flute design promotes efficient chip removal and accurate cutting performance, while the 3-flats reduced shank provides a secure, slip-resistant grip in the drill chuck. Made from premium high-speed steel (HSS) with a black oxide finish, this reamer delivers long-lasting durability and consistent results. The short screw machine length increases rigidity to reduce breakage. Proudly made in the USA for reliable quality and performance.
