Description
Drillco 427E152 13/16 Spiral Flute 1/2 Shank Construction Reamer is engineered for heavy-duty reaming in structural steel fabrication and other demanding metalworking applications. Its tapered point allows smooth entry into misaligned or undersized holes, ensuring precise alignment and accurate sizing. The spiral flute design promotes efficient chip removal and consistent cutting performance, while the 3-flats reduced shank provides a secure, slip-resistant grip. Made from premium grade cobalt high-speed steel (HSS), this reamer can drill harder materials approximately 30% faster than standard HSS. The bronze surface treatment adds high lubricity, and the shorter screw machine length increases rigidity to reduce breakage during use.
