Drill Doctor 500SPK 3/32 inch - 1/2 inch Precision Drill Bit Sharpener... Drill Doctor MORE INFO

Although drill-bit sharpening systems often fail to live up to our expectations, we're here to bear witness for the truth of the Drill Doctor's claims: it really does sharpen old bits in just a couple of minutes. The 500SP (also known as the Tradesman) works on conventional, split-point, and masonry bits. It can sharpen bits from 3/32 to 1/2 inches in size, and though the machine will also work for 3/4-inch bits, we'd recommend buying the Professional model for doctoring these big boys, as it comes with a special chuck the 500SP lacks. Both models--the 500SP and the Professional 750SP--allow you to choose between a 118- and 135-degree sharpening angle. Operation is fairly simple, but to make sure no one has trouble figuring it out, the Drill Doctor comes with a how-to video. Anyone who frequently wears down drill bits is going to appreciate the savings this handy machine can offer. Using sharp bits instead of dull ones also increases the life of your drill, because sharper bits require less work to make the same hole. We only wish we'd found the Drill Doctor sooner. --Brian Trinen From the Manufacturer Sharpen it up. Renew dull, worn-out drill bits to precision sharpness, saving time and money.
