Description
Drillco 427A228 1-7/16 Spiral Flute 3/4 Shank Construction Reamer is engineered for heavy-duty reaming applications in structural steel fabrication, bridgework, and assembly operations. This construction (car) reamer features a tapered point that allows smooth entry into misaligned or undersized holes, ensuring precise and efficient hole enlargement. The spiral flute design enhances chip removal, reduces heat buildup, and improves cutting performance in demanding industrial environments. Made from premium-grade high-speed steel (HSS), it delivers long-lasting durability and reliable performance. The self-centering 135° split-point reduces walking and lowers thrust for controlled, stable cutting. Black oxide surface treatment increases tool life by providing wear and corrosion resistance. The shorter screw-machine length adds rigidity to minimize breakage, while the 3-flats reduced shank ensures secure, slip-free gripping in the chuck.
