Hex Shank Tap Drill Bit Combo, Titanium Coated HSS

Three operations, one bit, one chuck

• Drill, chamfer and tap in one

  The tip starts the pilot, the next section breaks the edge of the hole, and the threaded flutes finish the job. You never pull the bit to change tools, which is where most crooked threads begin.

• Fits the drill you already own

  The 1/4 inch hex shank runs in standard cordless drivers and impact drivers. The flats grip the chuck, so the bit turns with the driver instead of slipping in the jaws.

• Titanium-coated cobalt body

  Cobalt HSS carries the cutting load in hard metal. The titanium-coated thread section adds a slick, hard surface that helps the teeth cut with less hand effort. The black-oxide band on the shank marks where the bit stops.

Drill, chamfer, tap in three passes

1. 1
   Drill the pilot square

   Set the bit square to the surface and drill the pilot at slow speed. Keep the driver steady so the tip does not wander.

2. 2
   Chamfer the entry

   Keep the same bit turning and let the chamfer section break the edge of the hole. A clean entry helps the first thread start straight.

3. 3
   Tap in forward passes

   Turn in short forward passes and back off every few turns to clear chips. On steel and stainless, add cutting fluid before each thread.

The swap that ruins a straight thread

The swap that ruins the hole

You drill the pilot, pull the bit, reach for a tap and start turning by hand. Halfway through the thread the bit wanders and the hole finishes crooked. Every changeover is another chance to lose the start.

One bit, one chuck

The hex shank seats in the driver chuck and the same bit drills the pilot, cuts the entry chamfer and taps the thread. Nothing comes out between steps, so the drill stays square to the work from the first pass to the last.

A straight thread, done

The cobalt body and titanium-coated thread section cut clean with steady drill pressure. The thread starts true, the fastener seats square, and the afternoon goes back to the project.

What to expect as you use the set

1. First Use
   First hole done in one setup

   Drill the pilot, chamfer the entry and tap the thread with the same bit. Expect slow, steady passes and a clean first thread.

2. 3 Uses
   Chuck and rhythm feel natural

   You learn how much pressure the driver needs and when to back out to clear chips. Passes get quicker as the motion becomes familiar.

3. 30 Days
   The set becomes your go-to tap

   Regular use shows how the coating and cobalt body hold up on your materials. Check the threads on your own work to judge wear.
