Does anyone have experience with the Drill Doctor? Does it really work well? What is the best place to buy one or where can I get a good tool to sharpen my bits?
Also, does anyone have advice on where to get drill bits for drilling into1/4" mild steel? Even with reduced speed and constant lube, my bits are dull after only a few holes. Cobalt seems to work better but still doesn't last long. Anyone know where to get carbide bits for drilling into steel?
