With the Drill Doctor 750X Euro Plug, you simply align the bit by setting it against the stop and locking it in place. To sharpen the bit, you turn the chuck an even number of half turns, depending on the size of your bit. As you sharpen, long jaws hold the bit precisely in place, and jaw guides eliminate jaw twisting on small bits. This secure alignment system ensures that you maintain accurate bit geometry and don't damage the integrity of your tools. Once the bit is sharpened, the Drill Doctor 750X gives you the option of making a unique BACK-CUT split-point bit that gives your bit an extra-narrow chisel point, Additionally, the drill point splitting port offers a "Push to Stop" design that will prevent over-splitting the bit point. Engineered for Versatility and Flexibility the same chuck can be used to sharpen bits of all sizes, from 3/32- to 3/4-inch, whether they are English, metric, or letter gauge bits. The Drill Doctor 750X features a metal split-point port and a die-cast point angle shuttle. As a bonus, the Drill Doctor 750X comes with a rugged shell case, making it easy to transport to the job site.
