Drillco 1/2 Spiral Flute 1/2 Shank Construction Reamer (427E132) (Model 4.27E+134)
Drillco 427E132 1/2 Spiral Flute 1/2 Shank Construction Reamer is built for heavy-duty reaming in structural steel fabrication and other demanding metalworking applications. Its tapered point allows smooth entry into misaligned or undersized holes, ensuring precise alignment and accurate sizing. The spiral flute design promotes efficient chip removal and consistent cutting performance, while the 3-flats reduced shank provides a secure grip to prevent slippage. Made from premium grade cobalt high-speed steel (HSS), this reamer is capable of drilling harder materials approximately 30% faster than standard HSS. The bronze surface treatment adds high lubricity, and the shorter screw machine length increases rigidity to reduce breakage during use.
