Drillco 19/32 Spiral Flute 1/2 Shank Construction Reamer (427A138)
Drillco 427A138 19/32 Spiral Flute 1/2 Shank Construction Reamer is designed for heavy-duty reaming tasks in structural steel fabrication, bridgework, and assembly operations. As a construction (car) reamer, it features a tapered point to allow smooth entry into holes that are misaligned or undersized, ensuring precise and efficient enlargement. The spiral flute design enhances chip evacuation, reduces heat buildup, and improves cutting performance, making it ideal for demanding industrial environments. Made from premium-grade high-speed steel (HSS), it delivers exceptional durability and wear resistance. The self-centering 135° split-point minimizes walking and reduces thrust requirements for better control and accuracy. A black oxide surface treatment further extends tool life by protecting against corrosion and wear. The shorter screw-machine length increases rigidity to reduce breakage, while the 3-flats reduced shank ensures a secure, slip-free grip in the chuck. Made in the USA for consistent performance and quality.
