The first thing I would say about the Drill Doctor 750X is that there is a bit of a learning curve. There are a lot of instructions and steps, but once you get the hang of it it is rather intuitive. I played around with some very old and very cheap bits initially until I really got the hang of using the process. There is no doubt in my mind that Drill Bits were sharper after using the Drill Doctor. You can see the change in how well the bits drilled, the right holes being drilled just prior to sharpening and the left being just after. For instance, a lathe is a wonderful tool to have, but it has a steep learning curve and can be intimidating if you don’t know what you’re doing or have someone to teach you.

You can also expect that every DrillDoctor model will have a wide firm base to prevent the unit from shaking its way across the table while in use. This model is significantly more expensive than a Drill Doctor or the other competitors we’ve mentioned. However, the Drill Doctor DD750X has many more options than the DD500X’s two angles. It’s cutting wheel can be set at any angle between 115 degrees and 140 degrees, which allows you to use and sharpen non-standard bits. Both these sharpeners come with a pre-installed 180-grit cutting wheel. However, if you need something a little rougher you can get the 100-grit wheel and trade it out with the 180-grit option just like you were replacing it. However, if you regularly work with reversed drill bits, this accessory will help you extend the working life of those bits just like you would with a regular bit. Replacement Parts

The same goes for metal workers or anyone working with particularly dense materials that need a specialized bit. The Nitty Gritty: Some Differences to Consider The standard sharpening port has an angle shuttle that can be set at any angle from 115 to 140 degrees with stops at the standard 118, and 135 degrees. The angle shuttle is also made of cast aluminum for extra durability. Setting the angle is as simple as turning a knob on the right and shifting the shuttle up or down, then retighten the knob. Sure, the process is self-contained so you aren’t likely to see little metal shavings flying all over the place, but you should think about how much time you are willing to put into learning and experimenting with these machines before you decide which one you want to buy. If you do a lot of drilling, a drill bit sharpener a smart buy. It saves you time, because you won’t waste minutes struggling to drive a dull bit through your workpiece. And it saves you money, because you aren’t throwing out dull bits all the time. You want to do this an even number of times so each flute is sharpened equally. The number of turns required depends a great deal on the size of the bit. According to the owner’s manual, a 3/32-inch bit may take 2-4 half-turns while a 3/8-inch bit might take 16-20 half-turns. It’s easy and takes very little time.

So for me, sharpening drill bits by freehand grinding was not an option. That left me with the following choices for dealing with my dull drill bits: The ability to create split points should be especially valuable for any fine-grain wood project as split point bits help to prevent damage to the wood outside the drilled area from ‘walking’ as you start to drill. Drill Doctor does note that you may get more uses, but you’ll see declining performance if you push the 200-use limit too far. Compatible Drill Bit Materials Tormek’s T-8 model sharpener doesn’t specialize in drill bits the way the Drill Doctor does, but between the professional grinding system and the additional feature of a water-cooling system, the T-8 can handle almost any sharpening job you throw at it. Adjustable material take-off: Allows user to change the amount of material removed during sharpening to further extend the life of your bitsA family-owned company called Darex owns Drill Doctor. Darex specializes in sharpeners for bits, outdoor products, and kitchen knives. Drill Doctor themselves have been around for a while and are US based, including their manufacturing. There are a few versions of the Drill Doctor bit sharpener, and over the years they have continued to evolve and include even more features. Today, we will be looking at their current higher-end model, the 750X. Drill Doctor 750X Review Features Adjustable material take-off: Allows the user to change the amount of material removed during sharpening to further extend the life of your bits There really is only one difference in terms of included features between the two models, the DD750X comes with a bag for transporting the tool from place to place. If you want a transport bag for the Drill Doctor DD500X you need to buy it separately. We’ll talk about the similarities and differences between these two machines, what you can expect to arrive in the box with the sharpener, some pros, and cons of each option, and give a solid recommendation as to which sharpener we think is the best deal.
