Yes, but you should practice with a 7 first.
A 1/4-inch bolt with a 20-thread-per-inch pitch would be used. These work great and eliminate the need for separate tap drill bits.
As long as the screws require 1/4" 20 threads, the DWADT1420 should work in this situation.

Ugh. This Dewalt Drill Tap is incredible, so don't waste your time. Tap to speed up the bit! This bit is perfect for tapping aluminum 5000, 6000, and occasionally 7000 series AI, and it's well worth the money. br>br>One word of caution: if the material you're drilling is flammable, it's best to avoid it. If the tapping is thicker than the speed bit length and hasn't drilled through material before engaging it, you may run into problems; the TAP is already working hard enough and doesn't need or want any more resistance. When bits break or won't thread properly, this is the most common scenario. This is a USER ERROR, not a tool error. Pre- TAP after drilling the proper size hole in thick material. Use bearing oil or something similar to reduce heat when working with metal, and your bit will last for a long time!br>br>Highly, Highly, Recommend!.
This is a fantastic idea. Drilling and tapping is a blast. However, it does not work out very well. 1/8-inch aluminum plate is being drilled and taped. I noticed the bit was working too hard and decided to drill a hole first. That's very useful information. The bit shattered on my fifth hole. On my MILWAUKEE 2760-S, I was using the lowest speed setting. Fuel Hex Hydraulic Driver, 20 M18, 1/4 in. This is, of course, a very strict and temperate bit. However, it made me want to return to my hand twist taps. br>br>Perhaps DeWalt and others should simply develop a 1/4" drive impact TAP. not using the drill.
The bit should not be snapped, they warned. "Impact ready" is a claim made for this product. " I did, in fact, use them as a tap with my impact driver; Throughout the process, however, I made sure to use cutting oil on a regular basis and to keep the driver's RPM low. According to my limited understanding, impact torque increases with RPM, so keeping the torque low reduces the risk of snapping your bit. All I have to say is that I tapped three holes with the bit, and it worked flawlessly!.
I tried to make a camera mount out of a 1/4" aluminum plate by drilling and tapping it. The plate was ruined after it broke halfway through the imbedding process. For nothing, I thank you.
This drill and tap is excellent, and I assisted it by drilling a pilot hole to reduce the risk of fracture. I used it for over 50 holes before it became clogged and broke. I purchased four of them in order to complete the project I was working on.
I really like it. Drilling and tapping at the same time is a brilliant idea. It really works. Now that I've tried it, I'm going to need a full range of sizes. I tapped my metal leg hard so I could attach flippers and other equipment to swim faster.
These work well as long as the diameter of the hole is less than 1/4" and you don't let your gun "hit it too hard. " So, when cutting threads, don't pull the trigger too hard and make sure your work is thin enough, and you'll be pleased with the results.
When I first used the first one I bought, it broke. I am very pleased with the second one, which I received after waiting for Amazon to send another.
