Greenlee 7-Piece Drill/Tap Bit Kit for Stainless Steel with Titanium Nitride Coating and High-Speed Steel Construction

Professional drilling and tapping solution for stainless steel and multiple materials

The Greenlee 7-Piece Drill/Tap Bit Kit delivers professional-grade performance for stainless steel, mild steel, aluminum, brass, copper, fiberglass and plastics applications. Constructed from high-speed steel with titanium nitride coating, this comprehensive kit provides superior resistance to heat and abrasion while ensuring extended tool life. The optimized core design significantly reduces torque on the user, and the split-point tip resists walking while penetrating material faster for efficient drilling in up to 1/4" thick material.

Professional Features & Benefits

  • High-Speed Steel Construction: Provides superior resistance to heat and abrasion for demanding professional applications and extended service life.
  • Titanium Nitride Coating: Ensures bits run cooler, drill faster, and last longer while maintaining cutting performance across multiple materials.
  • Split-Point Tip Design: Resists walking and penetrates material faster for precise hole placement and improved drilling efficiency.
  • Optimized Core Technology: Significantly reduces torque on the user while extending tool life through improved stress distribution.
  • Complete Size Range: Includes 6-32, 8-32, 10-24, 10-32, 12-24, and 1/4-20 sizes for comprehensive threading applications.
  • Durable Case & Quick-Change Adapter: Includes protective storage case and quick-change adapter for efficient tool changes and organized storage.

Greenlee DTAPSSKIT – Frequently Asked Questions

1) What thread sizes come in the Greenlee DTAPSSKIT drill/tap bit kit?
The Greenlee DTAPSSKIT covers six machine screw threads: 6-32, 8-32, 10-24, 10-32, 12-24 and 1/4-20. Those are the sizes an electrician actually uses for mounting devices, ground screws and enclosure hardware. The seventh piece in the kit is the quick-change adapter, along with the storage case.
2) How thick a material can a Greenlee drill/tap bit handle?
Up to 1/4 inch thick. That covers strut, enclosure walls, panel backs, sheet stainless and steel angle, but a drill/tap bit will not thread deeper stock, so for thick plate you need a separate drill and hand tap.
3) Can I use these bits on stainless steel enclosures, or is stainless too hard?
Stainless is what this kit is built for. The bits are high-speed steel with a titanium nitride coating, which runs cooler and resists abrasion, and the kit is also rated for mild steel, aluminum, brass, copper, fiberglass and plastics. Keep the speed down and the pressure steady on stainless, as HSS work-hardens the hole if you let the bit dwell.
4) Do I need to center punch before using a Greenlee drill/tap bit?
The split-point tip resists walking, so it bites where you set it without a punch mark on most sheet work. On a curved or polished surface a punch still helps. The point also penetrates faster than a standard 118-degree tip.
5) Does a drill and tap combination bit replace buying separate drill bits and taps?
For sheet work up to 1/4 inch, yes. Each bit drills the pilot and cuts the thread in one pass, so you are not swapping between a drill index and a tap handle on a ladder. Where it does not replace separate tools: anything thicker than 1/4 inch, blind holes that need a bottoming tap, or pipe threads. This kit is the one-pass option for 6-32 through 1/4-20 in panels and sheet metal.
6) Will these bits work in a cordless impact driver?
The kit ships with a quick-change adapter for compatible power tools, and the optimized core is built to cut torque feedback on the user. Run it at a controlled speed rather than hammering it, since tapping needs steady rotation to form a clean thread.
7) What is the Greenlee stainless drill/tap kit part number for ordering?
Order it as Greenlee DTAPSSKIT, the 7-piece drill/tap bit kit for stainless steel. It is a single configuration, so there are no finish or size options to specify.
8) Is a titanium nitride coated bit worth it over plain HSS for panel work?
On stainless and repeated holes, the coating earns its place: TiN lets the bit run cooler and hold its edge longer than uncoated high-speed steel, which matters because drilling and tapping in one pass generates more heat than drilling alone. For occasional holes in aluminum or plastic the coating makes less difference.
