Description
Drillco 427A220 1-5/16 Spiral Flute 3/4 Shank Construction Reamer is designed for heavy-duty reaming applications in structural steel fabrication, bridge construction, and automotive assembly work. This reamer excels at enlarging and aligning holes in metal components with high accuracy. The tapered point allows smooth entry into misaligned holes for precise results. Its spiral flute design improves chip removal and ensures smoother cutting action. Made from premium-grade high-speed steel HSS, it provides exceptional durability and long service life. The 135° self-centering split-point reduces walking and lowers thrust requirements, while the black oxide surface treatment enhances wear resistance. The 3-flats reduced shank provides a secure grip in drill chucks. Proudly made in the USA.
