Drillco 15/32 Spiral Flute 15/32 Shank Nitro Construction Reamer (427N130)
Drillco 427N130 15/32 Spiral Flute 15/32 Shank Nitro 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. Featuring a Nitro surface treatment with black and gold coating, this reamer achieves increased hardness without brittleness and delivers maximum lubricity. Made from premium grade cobalt high-speed steel (HSS), it can drill harder materials approximately 30% faster than standard HSS reamers.
