QUICK & ACCURATE - Quickly enlarge holes in material up to 1/2" thick. Each step reamer has five sizes, in 1/16" increments, for accurate hole enlargement.
HIGH-PERFORMANCE COATING - Aluminum Chromium Nitride (AlCrN) coating provides added lubricity to quickly extract cut material, providing longer life and faster hole creation and enlargement.
SPLIT POINT - Self-centering split point starts a hole from scratch up to two times faster than standard step reamers.
FLATTED SHANK - Three flats on the shank help eliminate spinning or slipping in the chuck.
SUPERIOR HOLE QUALITY - The step reamer accurately enlarges holes while the chamfer on the next step removes burrs and creates a finished edge.
