3/8" Bridge Construction Reamer Drill Reamer Tool Set For Metal, M2 HSS Car Reamer Tapered Alignment Reamer Drill Bit Chucking Steel Reamers Spiral Flute With Shank Chuck

High-speed Steel Bridge Reamer - Bridge reamers are installed in a compatible power tool to enlarge, debur, and finish holes in structural materials to a specific size. The reamers have tapered flutes that ease the tool's entry into rough-cut or misaligned holes.
Straight Shank with a Safety Collar - These bridge reamers have a straight shank with a safety collar that prevents the reamer from going too deep into the workpiece during reaming operations.
Spiral Flutes - Reamers with spiral flutes are a good choice for materials that are difficult to ream, such as high-carbon steel and cast iron, also create a fine finish and reduce the chance of breakage because they move chips forward, which prevents the chips from packing into the flutes.
M2 Heavy Duty Construction Reamer - Construction alignment reamers are designed for reaming difficult-to-machine materials such as iron and structural steel in metalworking applications where extreme precision is not required.
Widely Application - Bridge car alignment reamers are used to ream rivet holes in parts for automobiles, bridges, rail cars, ships, and pressure vessels. Specially used in structural materials such as steel, metal, alloy, aluminum, brass, plastic, iron, nickel, copper, cast iron etc.
