Milwaukee SHOCKWAVE 8 in.- 32 in. Steel Drill Tap Bit

With this, I was able to correct stripped threads in my father-in-law’s overhead light box with ease. Screws now glide in like they should.

I’ve used several other brands that break. I’ve had no issues with it. Since this is one solid piece, it’s super sturdy. I see this lasting for a long time!

Ever want to be able to drill and tap a hole at the same time? Then the SHOCKWAVE 8 IN.- 32 IN. STEEL DRILL TAP BIT is definitely a must buy! I’ve only used it on a softer metal and it made a hole really easily and tapped the treads with precision and ease. I used a little cutting oil and my handheld Ryobi drill to cut with. The drill tap bit will speed up my future projects.

Great for cleaning up threads in electrical junction boxes

Milwaukee Tool 8-32 UNC Shockwave Impact Duty Drill and Tap Bit 48-89-8970 is a stout bit that cuts 32 threads per inch. You use a #29 drill bit with this that is actually .1360″ or .0136″. It uses a ¼” shank so you can use impacts. This does a great job. I needed to buy some drill bits and got cobalt jobber length to work with this. Heavy Duty and will cut for a while. You could use this to drill as well. Meant for metal up to ¼” thick. Quality. Durable.

Saves time and effort. Hard to imagine why any professional or weekend woodworker would not keep one in his/her tool kit.

Will brake if you use it with your impact drill..

Excellent, well manufactured bit for simultaneous metal drilling and tapping. The bit starts out quickly without walking across the surface and does not need a tap point to hold in place. If your material is thick enough to hold it, you can even countersink the hole all in the same motion with one bit. I have not experienced any noticeable flaking from the bit. It does not need oil to drill.

The Milwaukee shockwave steel drill tap bit works well to both drill and immediately tap into metal in the same operation. I found it to be well designed and operate as expected. One thing to be aware of when using it is to be mindful of the depth of the thread capacity when working with thin material. Fully running the bit through the stock can cause the bit to run out of threads. This is not a huge problem, but can cause a little grief to get the bit out after the tap process by restarting it in reverse. Just be careful to slowly do the tap portion of the job to save some time getting the tool out of the stock.
