Greenlee 52066985 7-Piece Drill/Tap Bit Kit for Stainless Steel, HSS

The Greenlee 52066985 7-Piece Drill/Tap Bit Kit for Stainless Steel is a standard combination drill and tap bit set built for electricians and installers who need to drill and tap holes in stainless steel enclosures, panels, and boxes in a single step. Constructed from High-Speed Steel with a Titanium Nitride finish for added wear resistance, each bit features a Split-Point Tip that helps prevent walking and delivers a clean, accurate start on stainless steel and other tough metal surfaces. The kit includes six of the most commonly needed thread sizes for electrical and mechanical assembly work: 6-32, 8-32, 10-24, 10-32, 12-24, and 1/4-20, giving installers the coverage they need for a wide range of fastening applications without carrying multiple single-size tools. A quick-change adapter and durable storage case round out the kit for fast, organized use on the job site or in a service truck.

Key Features

  • Durable Construction: Made from High-Speed Steel for strength and heat resistance during repeated drilling and tapping cycles.
  • Titanium Nitride Finish: Applied coating improves wear resistance and helps extend bit life when working in stainless steel.

  • 7-Piece Kit: Includes drill/tap bits sized 6-32, 8-32, 10-24, 10-32, 12-24, and 1/4-20, covering common electrical hardware thread sizes.

  • Durable Storage Case: A dedicated case is included to keep all bits organized and protected on the job or in a truck.

Greenlee 52066985 – Frequently Asked Questions

1) What thread sizes come in the Greenlee 52066985 drill/tap kit?
Six thread sizes are covered: 6-32, 8-32, 10-24, 10-32, 12-24, and 1/4-20. Those are the machine screw threads you hit most often mounting devices, straps, and brackets to steel enclosures, so one case covers most panel work without hunting for a single-size tool. The seventh piece in the 7-piece count is the quick-change adapter, and a storage case is included.
2) Will these drill/tap bits actually cut stainless steel enclosures?
Yes, that is what the 52066985 kit is built for. The bits are High-Speed Steel with a Titanium Nitride coating for wear resistance on hard metal, and each has a split-point tip that self-centers so it won't walk across a smooth stainless panel. Run it slow with steady pressure the way you would any HSS bit in stainless.
3) Do I need a separate tap after drilling with this Greenlee kit?
No. These are combination drill/tap bits, so a single tool drills the hole and cuts the thread in one pass. That is the point of the kit for panel and box fabrication: no swapping to a tap handle, no pilot-then-tap sequence on an enclosure you are holding overhead.
4) Can I swap bit sizes without rechucking the drill?
Yes. A quick-change adapter ships with the 52066985 kit, so you drop from a 6-32 to a 1/4-20 by pulling the bit out of the adapter instead of opening the chuck. Useful when a single enclosure needs two or three different screw sizes.
5) Is this kit only for stainless, or can I use it on regular steel panels and boxes?
The 52066985 set is specified for stainless steel, which is the harder case. HSS with a TiN coating and split-point tips works the same way on mild steel enclosures and galvanized boxes, which is where most panel and box fabrication actually happens. Stainless is the limit it was rated against, not the only material it handles.
6) How big is the case on the Greenlee 52066985 kit, and will it fit a service truck drawer?
The kit measures 9.16 in long, 6.2 in wide and 1.16 in high, so it lies flat in a van drawer or the lid tray of a tool box. Total volume works out to about 65.9 cubic inches.
7) What is the Greenlee part number and UPC for the 7-piece stainless drill/tap kit?
Order Greenlee 52066985. The UPC on the package is 783310025801. One model, no size or finish options to specify.
8) Where is the Greenlee 52066985 drill/tap bit kit made?
Country of origin is China. Worth knowing if you are filling a government or institutional order with domestic-sourcing language in the spec.
