Description
Drillco 427A146 23/32 Spiral Flute 1/2 Shank Construction Reamer is engineered for heavy-duty reaming applications such as structural steel fabrication, bridgework, and assembly projects. As a construction (car) reamer, it features a tapered point to allow smooth entry into holes that are misaligned or undersized, ensuring accurate and efficient enlargement. The spiral flute design improves chip evacuation, reduces heat buildup, and enhances cutting performance, making it suitable for demanding industrial tasks. Manufactured from premium-grade high-speed steel (HSS), it delivers excellent wear resistance and long service life. The self-centering 135° split-point reduces walking and lowers thrust requirements for improved control. A black oxide surface treatment further extends tool life by resisting wear and corrosion. The shorter screw-machine length increases rigidity, reducing the chance of breakage during high-torque operations, while the 3-flats reduced shank ensures a secure, slip-free grip in the chuck.
