Drillco 1-1/4 Spiral Flute 3/4 Shank Nitro Construction Reamer (427N216)
Drillco 427N216 1-1/4 Spiral Flute 3/4 Shank Nitro Construction Reamer is engineered for heavy-duty reaming in structural steel assembly fabrication. The Nitro surface treatment provides a hard, protective layer that increases hardness without brittleness, while the black and gold finish ensures maximum lubricity. Its tapered point allows smooth entry into misaligned holes for precise and efficient reaming. Made from premium grade cobalt HSS, this reamer can drill harder materials approximately 30% faster than standard HSS. The 3-flats reduced shank ensures a secure grip, while the larger 3/4" shank provides enhanced stability during operation.
