    Drill Doctor 750SP Drill Bit Sharpener, August 14, 2002

    By A Customer

    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.I then continued on, sharpening my Hanson 29 pc. HSS set, a couple of Vermont American 13 pc. HSS sets and a box of various sized loose HSS bits. Most bits took well under one minute to complete, and I wasn’t even hurrying. Almost all came out right on the first try. Any mishaps where easily fixed by simply repeating the procedure over again.As for savings, the 29 pc. set cost eighty dollars new, the 13 pc. sets were fifteen dollars each and there where at least thirty dollars worth of loose bits in the box. That’s about one hundred forty dollars of bits refurbished, minus around thirty minutes of my time. Keep in mind that this is only the first sharpening. It’s safe to say that most bits in reasonably good shape can probably be sharpened at least eight to ten times.One of the biggest and probably the most overlooked advantages of the 750SP is that it can also sharpen up to ¾” SDS type masonry bits. I used it to sharpen a small Bosch 5/32″ x 4″ [2"usable length], ¼” x 6″ and ½” x 6″ SDS bits. They are now good as new. I could never get them this sharp with just a file. This is about seventeen dollars worth of refurbished SDS bits and the sharpening process consumed all of about four minutes of my time. When you start getting into quality SDS bits sized ½” x 10″ to ¾” x 10″, then your beginning to look at real savings, with replacement costs at around sixteen to twenty two dollars per bit. My 5/16″ x 18″ and 3/8″ x 18″ bell hanger bits required two hands to steady and guide them while sharpening, but they all came out great and haven’t been this sharp since the day I bought them. As you can see, it just goes on and on.The 750SP’s comes with a carry case and the motor only draws 1.75Amps at 120V, so if you have an inverter in your truck, you can take it with you to the job and never have to worry about having anything less than the sharpest bit available. Supposedly you can get about two hundred sharpenings from one grinding wheel. Replacements grinding wheels cost twenty dollars and come in 100 grit or the standard 180 grit.I have absolutely no problem at all recommending the 750SP. It works extremely well and requires a minimal learning curve. If you are concerned about return on investment, I think you will easily see the 750SP and any replacement grinding wheels pay for themselves in short order by refurbishing your more expensive SDS masonry bits and quality HSS or cobalt twist drill bits. Additionally, having sharp drill bits readily available can go a long way toward helping reduce job productivity losses.

    - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - —- Note: Please see the end, because there IS an update to this story —- – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – – - – -(unedited original)Wrecked a considerable pile of drill bits with this one. Mine went “ziiiiing-tick” instead of the “ziiiiiing” the video tells you it should sound like. Just a tiny tick, but since I’ve never even seen a drill doctor before, and not knowing the “tick” was evil, I continued on. First bits were OK, but got worse very quickly. The angle was getting worse and worse on every bit I sharpened. Which led me to believe I was doing it wrong… so I kept practicing and watching the video, and practicing for hours until most of my drill bits were short and wrecked. By that time, the “ziiiiing tick” was a “ziiing-TWACK”, by the way.Being the curious guy I am, I removed the guard and side plug and put a strong light in front so I could see exactly why it was wrecking my drill bits, what was I doing wrong? Well, I found the grinding wheel was not firmly held down by the spring loaded twist-on retainer. I don’t know if the retainer wasn’t put on properly by the factory, or if the spring wasn’t seated correctly… all I can say is I could spin it with my finger at first, then it was tight after I removed it and reinstalled it)Any way, the momentum of the wheel allowed it to start grinding each bit, then the wheel would stop in the mid turn of the drill bit, while the motor continued to turn full speed. It’s quite loud, so there was no way to know this was going on without seeing it. The “tick” noise was cause by the shaft quickly spinning up the wheel when you finished the sharpening cycle of the bit and it pulled away. Of course every time the wheel was stopped, the shaft spinning it the middle of it ground some more metal away, making the wheel looser and looser, so the “tick” became a “twack”. The wheel stopped sooner as it got looser, which is why the bits were becoming worse for me, not better, with practice, LOL. The bits were all sharpened with a backwards angle, because the wheel spinning would grind down the leading edge of the bit and then skid to a stop, leaving the heel of the bit intact.)So , I call the 800 number, nobody there. call again, left message with name and number, nobody returned the call. Left message with receptionist, nothing.I called pretty much every day, actually for well over a week. Left lots of messages. Receptionist left messages for them too. The receptionist was even saying “wow, nobody has phoned you back yet?? ” after a week.Eventually, about 10 days later, I finally get a hold of somebody (note that they still hadn’t returned a voicemail yet), and I explain it to them. They can’t do anything about it, and all I get was another number to phone for the repair tech. sigh)So that guy only takes two days to get a hold of, and I explain it to him.All I wanted/expected was to send in my receipt (receipt dated about 15 days old now) and the wheel/retainer, which is now all stripped out, and get a new wheel and retainer on warranty (PS this machine is brand new). Nope. I have to mail the entire unit to them, they will “fix” it or send me a refurb. The guy says probably a refurb, since he isn’t allowed to disassemble them in any way. (! The guy seems nice enough, and explains his hands are tied since Drill doctor won’t mail him any parts either.Shipping the ENTIRE unit across the country costs almost twice than just going and buying the grinding wheel at a local store to begin with! Ugh. Phoned the original 800 number a bunch more times, nobody there, nobody phones back. Over a week later somebody actually calls me back (from the first voicemail I assume, 22 days prior), and the result is the same.No, I can’t mail the screwed up wheel and retainer to them for warranty replacement. Mail the entire (brand new) unit in to Drill doctor (at my expense), and they’ll ship you a refurb. They don’t do “parts” at all, apparently.So, end result is, I bought a new wheel, fixed up the retainer a bit to properly hold it down, it works fine. Not “superb” or “like new” , but considerably better than hand sharpening for sure.My view of Drill Doctor as a company, and their customer support? I really *hope* I never need warranty again. That was a terrible experience. You really get the feeling that nobody really cares there, but the receptionist who unfortunately can’t do a thing for you.Things break, that’s a expected. And sometimes things are DOA, that’s life. That’s what warranty is for.But when your only warranty support is an 800 number with voicemail, and they can’t be bothered to ever phone you back, that’s really horrible.The fact that they won’t send…

    Extends Life of Drill Bits, December 9, 2005

    This review is from: Drill Doctor DD750X Drill Bit Sharpener (Tools & Home Improvement)

    Upon receiving the Drill Dr., I immediately opened the box to find both an instruction manual and a DVD. The instruction manual is clear enough that, given you’re already a “handy-person”, a couple of reads is sufficient to get started. I have not opened the DVD. It takes ~20 minutes or so, after opening the box, to sharpen your first bit.The process, as described, begins with an overview of the machine, chucking the drill, setting the depth of material removal, setting the angle of the grind, and determining if the grind was properly achieved. Afterwards, you can perform a ‘split-point’ operation if desired.A few caveats. First, this is NOT a precision machine to be used for sharpening precision machine tools. Setting up the EXACT angle for grinding is difficult, and took me a few attempts. The two most common angles are 118-degrees and 135-degrees, for which the Drill Dr. has pre-set positions. Some of my drill bits are 130-degrees, made from HSS-Co. I suggest you start with a lesser drill bit that you can ‘sacrifice’ for the learning process. Second, during the sharpening process, you rotate the chuck (containing the drill bit) in the bushing that sets the angle. There is quite a bit of ‘play’ during this process, so it takes some care to ensure you are consistent during this operation. With more practice, it should not be a problem. Third, think twice before you do the ‘split-point’ operation. The radius of the split-point grind is OK for large drill bits, but will consume most of the drill-bit surface for anything under ~1/4-inch. Finally, it would be useful to have a rubber pad underneath the Drill Dr.. The grinding wheel is spinning ~20,000 RPM, and the Drill Dr. ‘walks’ across a hard surface.I do have some very expensive, precision HSS-Co bits that I won’t sharpen in this machine. Those bits I will take to a professional for sharpening. However, I do have some bits for general use, wood and steel, that will greatly benefit from this. My $150 set of general purpose HSS-Co bits can be rejuvenated, which will pay for the Drill Dr. immediately.Overall, highly recommended. I gave it 4/5 stars because of the difficulty in setting up the ‘non-standard’ grinding angle. After learning on a sacrificial bit, the process worked well. You can sharpen a bit in a few minutes, and they DO come out sharp. It works well for my all-around bits. I should have purchased a Drill Dr. years ago.
