Used for boring 6061-T6 forged aluminum. Made sure to re-apply tapping fluid when feeling slight friction before continuing. Also used it for tapping 5mm threads in the same 4.2mm drilled hole as recommended for best clearance. Thought I wanted a hex shank but the round shank is better for less wobble and precise concentric drilling since i used a hand held drill. Worked like a charm!

Do you need a 1 / 2 inch M35 cobalt drill? Yes, we have 12.7mm, which is 1 / 2 inch in English. **Q: is this good for 10mm rivet nuts?** A: I do not think so...since 10M rivet nuts have an od larger than the 10M screw it will facilitate. Here is how I know i.e. 1,2,3,4,5,6,7,8,9,10...etc. 10 is higher (larger diameter) than 8.9mm. You can search for a chart that will help you determine the size bit you need. It will be in the neighborhood of12mm I expect. Be sure to get someone to help you drill the holes if you can't hold the drill plumb. **Q: Confused by your size chart. Is the dia. of your 10.5 bit 10.5 or 9.6-10.5?** A: Not sure what chart indicated 9.6-10.5 mm. The bit shown in the listing should cut a hole of 10.5 mm with little error. What gets confusing for some is when a drilled hole is to be threaded (tapped). A smaller hole is needed and requires a smaller drill bit size than the bolt size/thread that must screw into the threaded hole. Hope I did not confuse you more. **Q: What is the length, how deep will it drill?** A: Total length 117mm, blade length 75mm ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Drill Bits! *by A***A on April 28, 2026* Cobalt drill bit worked great with tapping fluid.
