Hey all... i have been waiting a while to post this. it is a tool kit i bought for work but use in my laser stuff too. it is a kit by greenlee tools. it is drill bits that are combo drill and tap in one tool. i have been using them a while now. i mostly use the 10/32 and 1/4-20. i have tons of drill time on them and they are still super sharp. i drill slow speed with cutting fluid. the only draw back is that you cant drill deeper than the actual cutting/drilling tip. if you do then the tap part starts to catch and you will probably snap the bit in the hole. these tools are great for the diyer. i find them especially handy for making set screw holes in heat sinks. and now a pic. note, the pic is of a metric set but they come in standard as well.
