Glad I now have my own drill directory after borrowing from my dad all along. These items are very high quality and much sharper than most drill bits you will find. Sure, the price is a bit high, but I expect them to stay sharp and useful for years (although I'll probably have to replace the smaller sizes if they break). They don't break easily unless you misuse them. Don't overheat them by trying to run them too fast or too hard and they will be a much better investment than a cheap index drill that can barely drill through wood.
