About this item

  • Heat-treated carbon steel provides long life and clean, accurate threads
  • Rolled threads provide more accuracy than machined threads
  • Laser-etched marking ensures size identification won't wear off
  • Set Tailored for most general-purpose applications with premium efficiency


The Bosch Tap and Drill Bit Combo Set features five taps and five correspondingly sized drill bits. This helps ensure drilling the proper hole size before cutting internal threads. Plug taps are ideal for cutting right-hand internal threads; they are the most widely used type of tap, with three to five threads chamfered for general-purpose applications. The included drill bit is matched to the tap for the proper hole size. The bit is designed with split points to reduce bit walking for clean, accurate starts. The bit’s speed helix design promotes fast drilling. The plug tap is recommended when there is sufficient room on a blind hole and tapping to the bottom of a hole is not critical. Made from heat-treated carbon steel, it is a rust- and tarnish-resistant tool. The rolled threads are more accurate and cleaner than machined threads. They are tooled to the most exacting specifications to ensure that bolts anchor securely. Laser-etched marking ensures size identification and won't wear off. They feature a precise flute design to ensure fast and easy chip clearance. The included T-Handle tap wrench is used to securely hold taps to be turned by hand.

Just the thing for small household & equipment repairs. The taps & the bits are all in one well-organized case. The sizes are the ones most commonly found.Obviously, a much larger set would be more appropriate for people who routinely do shop work of various kinds. Most of us don't.

Die Gewindeschneider sind nicht für metrische Geinde, sondern für amerikanische UNC-Gewinde!

I wanted to up my game in making jigs for woodworking, which meant using some more accurate materials like aluminum. But tapping seemed intimidating. This set was just enough to get me the basics without overwhelming me with options. The sizes represented in this set match all the hardware I already had. Also, even without looking up tutorials, it was fairly obvious how to use the set for my first tap. The drill bits seemed better for aluminum than my existing bits, but I'm not a good enough judge of quality to say much more than that.

A great tool that makes installing through metal easier, just drill/tap and tighten. Not having to mess with a washer and nut reduces installation issues.

Generally a good product overall, but when I buy a small drill and tap set, I expect it to not begin with 6-32 as the smallest size. I expect it to also include 2-56 and 4-40 sizes, which it didn't, so I had to purchase them separately and add to the kit, significantly increasing my overall purchase price!

Recently I have been doing some projects that require me to tap or retap a hole. I decided to purchase this kit for the occasional use that I have as a hobby user. I fully expect that the taps and drill bits will not hold up to extensive use and can accept that I will need to replace the components as that dull. I really like the storage case and the ability to store a few taps as spares in one place. Good value for the money but wish they offered a kit without the handle as I have numerous handles from my machine building days.

I do woodworking, so I don't need to tap holes that often, so I can't say about long term use or how it works on different metals, ect.Used it to tap a hole in a socket to add an extension for my drill press table adjustment. Well, my son-in-law did it for me, he likes that kind of thing. The set worked very sell. Took a little work to drill the hole, but it was a socket, they tend to be a little tougher metal.The piece did tap well and the threads turned out perfectly. Taped a 1/4 hole and worked great.I picked this set because it had everything, the right sized drill bits, taps and handle. Plus a quite nice and durable case. Great to have it all right there in a box. Couldn't ask for any more.It arrived quick and was packaged well. Very happy with the product and can't think of anything bad to say. Well, the rod on the handle falls out easy, but that is not a big deal to me.
