Description

Drillco 427A208-132 1-1/8 Spiral Flute 1/2 Shank Construction Reamer is designed for heavy-duty reaming tasks in structural steel fabrication, bridge construction, and automotive assembly work. This reamer is ideal for enlarging and aligning holes in metal components with high precision. The tapered point allows smooth entry into misaligned holes for accurate results. Its spiral flute design improves chip removal and ensures smoother cutting action. Made from premium-grade high-speed steel HSS, it provides excellent 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 ensures a secure grip in drill chucks. Proudly made in the USA.
