totally pissed-off. I have replaced the grinding cylinder thinking that may be the problem to no avail. upon closer inspection, found the motor shaft has side-play in it. aprox 2 to 5 thousands of an inch and what even surprised me more the motor only has bushing in it no bearings which says heaps about the machine, Not meant to last at all, no wonder they sell millions of them. Now the machine Was brand new up until a few days ago. In my opinion cost of manufacture would be very little compared to what we pay. I live in Australia and it seems to me, in America,, Greed Is Good., hence send out a third rate product and make the max profit. Isn’t capitalism great, Make money at all cost and don’t give a damm about ripping people off. The extra stability also helps to reduce the noise the sharpener produces while it’s in operation, leading to a quieter workshop overall. Split Point Cutting Power 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

This model is significantly more expensive than a Drill Doctor or the other competitors we’ve mentioned. 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. Buy some kind of sharpening machine or jig– I can’t afford even a used commercial quality tool grinder like a Darex. That left either buying or making some kind of device for holding a drill at the proper angle against a grinding wheel, or buying a Drill Doctor or some other drill bit sharpener that is affordable enough for a home/hobbyist machinist. Masonry bits are just as easy, but they do require a couple of different steps in terms of lining up the bit and the actual sharpening process, but again they are just as easy to sharpen. Yet, split point bits can be difficult to find, mislabeled, or not labeled at all. With either the DD750X or the DD500X you can create the bit you need even when they aren’t locally available.The customizability of the DD750X also means that experienced craftsmen can experiment with different bit angles and points to create custom sets particular to their project needs. 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 Drill Doctor DD500X, since it only has two angle settings, is the easier of the two to learn and to use. That is one advantage of being a less flexible tool. The fewer things a tool can do, the fewer things you have to learn to make it do. 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.

The simplicity makes it easy to use on the most utilitarian bits, and it lets new users learn without the intimidation of a more complicated and flexible system.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. 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. The standard sharpening port also uses a unique design where you rotate the bit over the wheel to sharpen the bit. The port is slightly oval shape, allowing for perfect sharpening on the bit wings. This might be the option for you if you’re concerned about the learning curve on an automatic drill sharpener but still want something to extend the life of your drill bits. This is one category where the DD500X wins, hands down. The Drill Doctor DD750X is a more complicated, and therefore more intimidating, machine. Misc. Additional Features

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. Although both machines are similar in appearance, the DD500X’s simplicity means it is also less intimidating for new users or for workshops that focus on training. Now, both machines do come with a handbook, and you should absolutely read that handbook before attempting to sharpen even the cheapest and most easily replaceable drill bit. The main reason you would want to invest in the Drill Doctor is something you don’t see and that is to prolong the life of your drill. Just as a good chefs will sharpen their knifes, you should sharpen your drill bits before each major project. Besides a dull bit producing poor quality work, a dull bit will cause more wear and tear on your drills. You have to remember a drill is only a power tool that creates power and spins the bit. The bit is what actually does the cutting. A dull bit takes more power and work to make a cut than a sharp bit. If your drill is requiring more power, that means it creates more work and more heat for your drill. Now I am not saying if you use a drill bit one time, your drill is going to clunk out on you, but over time it does have an effect. It is very important to maintain sharp bits, just as it is important to maintain sharp saw blades when cutting wood.You might be asking yourself if I sharpen my bits all the time, won’t this just eat away the bit and soon I will have nothing left. Well, yes to an extent, but it would take a very long time. With the 750X you have the capability to use the adjustable material take off, so you have complete control of how much material you want to remove. This lets you fine tune the sharpening process and will make your bits last even longer.

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.The Drill Doctor doesn’t make much noise or vibration, and it will make even less if you operate it on a folded-up cloth shop rag instead of a hard surface. The ability to determine a custom angle allows you to create a bit for your specific needs. While this is undoubtedly an advanced function, it is critical for anyone who wants to save money on replacement costs for non-standard drill bits.
