Description
Drillco 428N141 .652 High Spiral Flute 1/2 Shank Nitro Construction Reamer is designed for heavy-duty reaming in structural steel fabrication, bridgework, and industrial assembly applications. The tapered point allows smooth entry into misaligned or off-center holes, ensuring precise and accurate hole enlargements. Its high spiral flutes and Nitro surface treatment improve chip removal, reduce heat buildup, and produce a clean, smooth surface finish. The 3-flats reduced shank provides a secure, slip-free grip in the chuck, making it ideal for demanding fabrication tasks.
