Drill Doctor DD350X Drill Bit Sharpener - 3/32" to 1/2" - Electric Sharpener - High Speed & Portable - for Steel, Masonry, Carbide & Tin-Coated Bits

wow this tool is great! It is really easy to use it sharpens the bits fast and really sharp too. This is my second one BTW, It is not the best in durability as the first one lasted about 1 year and then the chuck cam was wore out, Probably due to my Ogre strength I was a bit harder on it than I am on this one because of the plastic used to make it. Not sure how long I will get but I am sure longer than 1 year. I do not recommend a heaver ogre hand like mine (come to find out) all you need is a genital hand and soft touch. Just a few turns as well not like I was doing. I found out that 4 turns and my bit was sharp as the day it was new. I wish I had money to get the top of there line one but this one is really good. I was able to do all these bits in about 1 hour and they are very sharp! OH BTW that was a one handed hole I drilled in that piece of scrap while taking the video. And it went through that like a hot knife through butter!

I bought the Drill Doctor DD350X Drill Bit Sharpener for my son as a Christmas present, and it turned out to be a huge hit! He loves working on various projects around the house, and this sharpener has made his life so much easier. It’s incredibly easy to use right out of the box, and it brought his old, dull drill bits back to life in no time. The electric motor is powerful and efficient, and the whole unit is compact enough to be stored or carried anywhere he needs it. He was sharpening bits from 3/32" to 1/2" with no issues. The instructions were clear, and the process was quick—perfect for someone who values both speed and precision. Highly recommended for anyone who wants to save money on buying new bits and keep their tools in top shape! Great value for the price and a perfect gift for any handyman or DIY enthusiast.

Works great after you learn how to use it. First insert bit tightened just enough to hold it in the chuck. Make sure the alignment fingers in the chuck on both sides are against the edges of the bit flutes and again, on both sides. Align the white triangle with the cam guide and push bit into machine firmly. Then tighten chuck as much as you can, remove and tighten more. The tip of the bit should be sticking out no more than about 3/16". If it's sticking out more, redo the above. Turn the machine on and line up the straight line mark on the chuck with the cam guide on the machine. Now, this is IMPORTANT! Keep mild pressure UPWARD AGAINST THE CAM GUIDE as you turn the chuck to the right or clockwise to the double line mark on the chuck. Turn chuck to the right to the single line and again, keeping mild upward pressure on the chuck against the cam guide. Keep going from single line mark to double line mark and back again until the grinding of the bit sounds mild, smooth and uniform or just follow the guidelines in the instruction booklet. Also don't worry about pushing down on the chuck, just let the grinding wheel do it's job and AGAIN, keeping mild pressure UP against the cam guide. All this sounds somewhat complicated but once you get the drill down, (no pun intended), it's about as easy as operating a pencil sharpener. I sharpened around 120 extremely dull bits that thankfully I had saved instead of pitching them. To test some of the bits that before sharpening could barely cut into wood, I tried drilling the sharpened bits into mild steel and they cut into it like butter. Good job Drilldocter! I would have given this DD350X sharpener 5 stars as this is advertised to sharpen bits down to 3/32" but the alignment fingers in the chuck in my example seem slightly out of alignment and won't clamp on to the tiny bit flutes of 3/32" bits. Even so, I highly recommend this bit sharpener.

The sharpener does an amazing job. Used it to sharpen 1/8 thru 3/8 personally and the sharpened bits cut like new. I was drilling 'semi' hard steel and the bits dulled fairly quickly or the cutting edge chipped. The sharpener took care of both situations. immediately after sharpening the bits cut very well. Even after chipping the sharpened edge looked and worked like new.

I wish I would have purchased this product a long time ago it is the easiest and quickest way to sharpen bits it is fantastic

A great product for the price. Very easy to set up & use. I sharpened all my drill bits in a short time. Easy instructions. A fine product for a reasonable price! Would buy again. Highly recommended.

Sharpener takes a few tries to get the hang of but the instructions are thourough enough. The drill bits I sharpened were heavy-duty metal cutting bits though, and no matter how much I tried, they were never sharpened enough to cut metal again. They did fine with wood, but metal just smoked them as if they had never been resharpened at all. Plus the chuck/“alignment fingers” system doesn’t work with quick-change impact bits smaller than 1/4”, since the chuck maxes out on the quick-change shank before the fingers can tighten around the tip of the bit. If you’re a woodworker interested in keeping drill bits out of landfills, this is a fine device. If you’re a contractor interested in saving money, you’re better off just buying new bits.

I only used it a few times, but it actually made a few worthless drill bits work again. I should have bought this years ago. Not difficult to use, but follow the instructions exactly.

Excelente equipo, la verdad no tenia muchas espectativas pero me ha sorprendido lo sencillo que se vuelve afilar brocas. Fue un regalo de cumpleaños para mi padre y le gusto bastante, hizo la prueba enseguida. En casa las brocas se han afilado siempre a pulso con esmeril de banco y mucha paciencia, pero es tedioso para mi padre a sus casi 80 años, solo afilaba la que requeria en ese momento. Pero con el drill doctor en un par de dias revivio mas de 30 brocas que tenia guardadas y daba por muertas en batalla. Las instrucciones son algo confusas, pero es mas simple de lo que parece, colocas la broca en el broquero, ajustas lo suficiente para que quede fija pero pueda girarse dentro del broquero, luego giras un poco la broca en el sentido de perforacion que es en el sentido del reloj, esto para alinearla con las guias metalicas del broquero, despues coloca el broquero en el drill doctor alineando el triangulo con la parte superior y presiona solo un poco para que la broca retroceda y va a quedar en posicion para afilado, finalmente ajusta el broquero para que no se deslice la broca y sin apenas ejercer presion realiza un par de pasadas de I a II en sentido del reloj y comprueba, repite un par de veces y quedara lista. Si el angulo de la broca es muy cerrado o si esta rota, mejor pasarla primero en el esmeril de banco o en la mini amoladora para abrir el angulo lo mas cerca a 180 grados y tarde menos en afilarla, de lo contrario tardara mucho en desbastar hasta llegar al angulo deseado.

Well, I have to say I wasn't expecting this high quality of product and results. After watching a couple of YouTube videos from owners of the 350X I tried it out and, in the space of about 20 minutes I sharpened a dozen drill bits of various dullness. After each I could see the gleaming new metal on the drill bit and could feel the sharpness of the cutting edges. Excellent results, and easy too, after learning how to align the bit. Works great! If you are debating about buying a drill bit sharpener, just DO IT.

Hss sharpener

Me gusto mucho el producto.... es facil de usar y cumple con lo que se publica.... saca punta a las brocas...

It doesn't work on standard UK 240v power outlets. I'm sure the product runs fantastic in theory BUT if you're in the UK and planning on using it from your mains socket, it won't work. Plug it in and look forward to the fireworks.
