Greenlee DTAPKIT – Frequently Asked Questions

1) What thread sizes does the Greenlee DTAPKIT drill/tap kit cover?
The Greenlee DTAPKIT is a 6-piece set covering 6-32 through 1/4-20. That range takes in the machine screw sizes that most enclosure, strut, and equipment mounting work lands on, so you can drill and thread for 6-32, 8-32, 10-24, 10-32 and 1/4-20 fasteners without stopping to chase a tap and a matching drill separately.
2) How thick a piece of steel can the Greenlee drill/tap bits handle?
Up to 10 gauge. That covers most electrical enclosures, panel backplates, strut, and light equipment brackets. Material-wise it is meant for mild steel, copper, brass, and aluminum. Heavier plate or hardened stock is outside what these are built to cut.
3) Can you drill and tap a hole in one operation with the Greenlee DTAPKIT?
That is the whole point of the design. Each bit drills the hole, cuts the thread, and deburrs/countersinks it in a single pass with a power drill, so you are not swapping to a tap handle and turning threads by hand. On a panel with two dozen mounting holes, that is the difference between an afternoon and twenty minutes.
4) Do the Greenlee drill/tap bits fit a standard drill chuck or do they need an impact driver?
The bits use a hex shank and the kit ships with a quick change adaptor, so they seat in a standard drill chuck and hold without slipping. The hex shank also means they drop straight into a 1/4 inch hex quick-change holder if that is what you are already running on the job.
5) Is the Greenlee DTAPKIT high-speed steel or carbon steel?
Hardened high-speed steel throughout. Carbon steel taps dull fast in mild steel and snap in the hole, which is the expensive failure on a tap because you then have to drill it out. HSS holds an edge through far more holes, which is why this is the version you want if you are tapping enclosures day in and day out rather than doing one hole a month.
6) Will the Greenlee drill/tap bits walk when starting a hole on sheet metal?
They are ground with a split point and web thinning, which starts the hole where you put it and cuts the thrust you have to lean into. On a vertical enclosure wall or an overhead bracket where you cannot get your weight behind the drill, that matters more than anything else in the spec sheet. You still want a center punch on slick painted steel, but you are not fighting the bit to get it seated.
7) What keeps you from stripping the threads if you drill too deep with a drill/tap bit?
The bits are back tapered, so the threading section relieves behind the cut instead of continuing to bite. Over-run the hole and you are not chewing the threads you just cut. It is the design detail that makes single-pass tapping practical in a power drill, where you do not have the feel you get turning a tap by hand.
8) Can an electrician use these to mount devices inside a metal panel or enclosure?
Yes, that is the primary use case. Tapping the enclosure wall directly for 6-32 or 10-32 machine screws gets you a threaded mount without hunting for a nut behind the panel, which you often cannot reach once the gear is in. Same story for HVAC equipment mounting, strut brackets, and general fabrication in mild steel up to 10 gauge.
9) Do the Greenlee drill/tap bits work in stainless steel?
The material list for these is mild steel, copper, brass, and aluminum. Stainless work-hardens under a slow or chattering cut and is hard on high-speed steel, so it is not what this kit is specified for. If your enclosures are stainless, look for a tap rated for it rather than pushing these through.
10) What is the Greenlee part number for the 6-piece drill and tap set?
Greenlee DTAPKIT is the ordering number for the 6-piece high-speed steel drill/tap set covering 6-32 to 1/4-20. One part number gets you the full set plus the quick change adaptor; the pieces are not broken out under separate numbers here.
