AUTOTOOLHOMETitanium Combination Drill Tap Bit Set 13PCS SAE and Metric Tap Bits Kit for Screw Thread Drilling Tapping Deburring Countersinking

fantastic tool. It saves time by not having to change drills for taps. Great tool to have in your tool box.

Really liked the one-step value of drilling hole and tapping threads at the same time. Worked for me. :-)

I carry these in my tool bag. Every size I need is there. Really good product for the price.

Works great

I ordered to use on a plastic fitting for a pool where there were no threads in the screw holes. The screws needed to be screwed to attach both pieces in the water. Before use, it was almost impossible to screw two pieces of plastic together. I could not use a power tool with there being water.

Bought this to resize a set of existing m5 holes, in an aluminum rail, to m6. This should not be a hard task ... only a mm of material to be removed.1st day was ok ... Resized 4 holes and set in equipment hooks.2nd day, resized 1 hole ok and on the 2nd hole the bit snapped in half. The bit wasn't even warm ... So not an overheating failure. I wasn't pushing hard either.Product feels super light weight, which kinda surprised me from the onset. Maybe if you're tapping plastic, but I wouldn't recommend these for anything else.

These worked for a bit but then the 6-32 and 8-32 bits broke off in aluminum. Now I have to figure out how to get these broken drill taps out.

so far been really good
