Drill Doctor DD750X Drill Bit Sharpener

Wow, a drill bit sharpener that actually does as the manufacturer claims. To me, few things are more aggravating than trying to work with a dull drill bit, especially when working with steel. When considering the amount of time wasted and productivity lost whenever good sharp bits are needed on a job, but unavailable, it doesn’t take long to realize that it only makes good economic sense to be able to sharpen your own bits, especially for contractors and service/maintenance shops. Personally, I don’t mind spending a few minutes of my time, sharpening my drill bits, which I use on my jobs.
Like others, I had tried some of the useless, piece of junk sharpeners that came along in previous years and was a little apprehensive about trying yet another one. I’m glad I decided to try the 750SP. It really does have the ability to get your twist drill bits razor sharp, usually in less than one minute. You can also use it to convert standard point bits to split point bits. I thought it was going to be a pain to use, but the sharpening technique is simple and very easy to master. Alignment of bits over 1/8″ is done with the chuck by inserting it with the bit into the alignment slot. With bits smaller than 1/8″, you have to insert the bits into the alignment slot without the chuck initially and then slide the chuck over the bit after. This may sound a little cumbersome, but once you have the unit and do it one time, you’ll see that is actually not an issue at all, even with bits as small as 3/32″.
Watch the included video a couple of times, which is only about sixteen minutes in length, then read through the instruction manual and it will all come together.
The first bits I sharpened were 3/16″ x 4″, ¼” x 4″ and ½” x 6″ Relton percussion masonry bits. Now they are sharper than when new.
After sharpening, the tips of carbide masonry bits seem to have a more angular look than the original tip, but they work excellent. Refurbishing these first few bits saved about eleven dollars in replacement costs minus about six minutes of my time from start to finish.
