so, i need a 29 piece drill bit set for drilling metal. are the titanium or cobalt coated bits worth the money? snap on wants 180 for their bits and matco wants 160 something for irwin bits. not about to spend that much. i'd spend $100 for a decent set. what do yall think about these? or you got a better suggestion. http://www.thetoolwarehouse.net/shop/IRW-60138.html http://www.thetoolwarehouse.net/shop/IRW-73138.html http://www.thetoolwarehouse.net/shop/IRW-3018003.html http://www.sears.com/sr/javasr/product.do?cat=Power+Tool+Accessories&pid=00964073000&vertical=TOOL&subcat=Drill+Bits&BV_UseBVCookie=Yes http://www.sears.com/sr/javasr/product.do?cat=Power+Tool+Accessories&pid=00964086000&vertical=TOOL&subcat=Drill+Bits&BV_UseBVCookie=Yes my other question is, I bought an IR 7803 1/2" air drill.... it's nice, very powerful, but takes damn near forever to drill in steel, because it's slower. I used a coworkers 3/8" high speed air drill, and it cut a whole lot quicker. Is there a bit that works better for my slower more powerful drill, or should I just get a high speed 3/8" drill and stick a 1/2" chuck on it?
