Drillco construction reamer details
Drillco 1-1/8 Spiral Flute 3/4 Shank Nitro Construction Reamer (427N208)
Drillco 427N208 1-1/8 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, and the shorter screw machine length adds rigidity to minimize breakage during operation.
