Drillco 1.027 Spiral Flute 1/2 Shank Construction Reamer (427A201)
Drillco 427A201 1.027 Spiral Flute 1/2 Shank Construction Reamer is engineered for heavy-duty reaming in structural steel assembly fabrication. Its tapered point allows smooth entry into holes that are out of alignment, ensuring accurate and efficient enlargement. Made from premium grade HSS with a black oxide finish, this reamer provides long-lasting durability. The 3-flats reduced shank offers a secure grip in the chuck, while the shorter screw machine length adds rigidity to reduce breakage during operation.
