3/4"" Bridge Construction Reamer Drill Bit M2 HSS, 5 Spiral Flutes This 3/4"" bridge construction reamer is designed to align, enlarge, and smooth predrilled holes prior to installing bolts or rivets. Commonly used in bridge construction, steel erection, and fabrication work, it brings holes to precise size for proper fastener fit. Manufactured from M2 high-speed steel, the reamer features five right-hand spiral flutes with precision-ground cutting edges for efficient material removal and effective chip evacuation. The design supports consistent cutting performance and extended tool life when used with appropriate cutting oil. The bit includes a tapered lead point for controlled entry and a non-slip, three-flat 1/2"" shank to ensure secure chucking and reduced slippage during operation. A built-in stop feature helps control depth and maintain accuracy when reaming through material.
