Description

An 18-piece matched drill-and-tap set covering the nine most common National Coarse thread sizes from #6-32 through 1/2-13. Each tap is Norseman's Type 20-UB Magnum Super Premium spiral point plug style — the spiral point lifts chips ahead of the tap, preventing clogging in through-hole applications. Drills are matched to ideal pilot-hole diameter for each tap. Stored in an organized metal index case.
