Greenlee 50176161 – Frequently Asked Questions

1) Does the Greenlee 50176161 drill/tap bit drill and tap in one step?
Yes. The 50176161 is a combination drill/tap bit, so a single pass through the material drills the hole and cuts 1/4-20 NC threads. The split point with web thinning starts the hole without a center punch and reduces walking on sheet metal.
2) How thick a material can the Greenlee 1/4-20NC drill/tap bit handle?
Up to 10 gauge. Anything heavier than 10 GA is outside what this bit is rated to drill and tap, and you should drill and tap in separate operations with a standard bit and hand or machine tap.
3) Is this drill/tap bit the right size for 1/4-20 threaded rod or 1/4-20 bolts?
Yes. The 50176161 cuts 1/4-20 NC threads, which is the standard coarse thread on 1/4 inch threaded rod, hanger hardware, and 1/4-20 machine screws used for mounting boxes, straps, and trapeze hangers.
4) Do I need a separate pilot drill before using this Greenlee drill/tap bit?
No pilot hole is needed. The split point with web thinning does the drilling itself, then the threading section follows through the same hole. Keep the driver square to the work so the threads start straight.
5) What is the Greenlee part number and UPC for the 1/4-20NC drill/tap bit?
The manufacturer part number is 50176161, with UPC 783310176169. It is sold as a single bit, not a set.
