An Outstanding Tool
I got my new model 4300 rotary tool in July 2020 after having my last one for nearly 40 years. I am a prolific hobbyist and use it almost daily. The accessories and versatility of the tool is unequaled. As with any product there can be problems, but to date, my new 4300 has worked flawlessly!

    Fantastic tool, great attachments, fun to use
    [This review was collected as part of a promotion.] I have previously used other various rotary tools for hobby work. But when a special project came up (restoring one of my Grandfather's old knives for my brother as a gift) I wanted a tool that had more options, variable speed, and better accessories than the generic tools I had before. The 4300-5/40 was on sale at the time, so I snapped it up, along with a few other accessories, and turned some old bits of laced maple burl, walnut burl, and a small piece of ebony into new grips for the blade, and a decorative knife block. This was not about making really 'functional' grips, but restoring a knife that was the only keepsake my brother had of our grandfather. I used the various bits and tools for the 4300 to shape the grips as well as route out the knife block. It came out beautifully. The variable speed came in handy when working on the ultra soft laced maple burl and the extra hard ebony. My previous rotary tools would not have handled it with any ease at all.

      [This review was collected as part of a promotion.] I work these dremels to the bone! I use dremel exclusively for my projects. Sometimes running them hours at a time. I replace the brushes regularly and add a little lube for extended performance! I love my dremel!

        The End All of Do All
        [This review was collected as part of a promotion.] My original Dremel Mdl #270 moto-tool was over 40 years old when it finally gave up on me July of last year. It was a simple constant speed collet model and served me well, but my skills and the complexity of my projects have progressed significantly over the years. I decided on a new Dremel model 4300 variable speed tool with the accessory kit. An excellent choice for both beginner and experienced hobbyists and I feel it was more than competitively priced especially for the versatility it offers. I also paired it with a new model 220 Drill Press. I could not be more delighted with ability to turn out unique high quality projects and gifts! The variable speed and keyless chuck lets me drill, grind, sand, cut, and router quickly and flawlessly. I highly recommend this tool or any of Dremel’s fine line of products and accessories and I look forward to many more years of faithful service from this purchase. Please see the attached photos of projects I have completed since buying my new Dremel Tools.

            Variable speed
            [This review was collected as part of a promotion.] I bought this to replace my last one that burned out. I bought it because of the variable speed control on it and found out I like it so much better. When I'm carving birds I can slow it down to get into more detail work with it. I am also still learning about this tool, it's a lot of fun.

              What a great tool! So easy to use with the chuck, which takes all the accessories. I restored this 1920s lock box that was globbed with paint by using vinegar, and the dremel, and a tiny bit of black acrylic paint rubbed into the scratches.

              This rotary tool is well made. Quiet, Low vibration, Light weight, And very versatile. The pen attachment is very handy for my dogs nails as well as doing detailed stone carving. I was surprised with how nice the carrying case is. It would be nice though if it came with a detailed list of attachments/Inserts and what they are suitable to be used for. I'm not very good with search engines so it took me a while to find the bit I needed. I've had this tool for about 3 months and can't really find any problems with the tool itself.

              Scary fast!!! Love, Love,$it!!! The extra amperage in the 4300 series. Makes you actually need to slow it down from time to time. Just because it cuts so fast. I sometimes cut off a little more than planned. That's a personal issue and no fault of this amazing tool. So versatile, that when I think there's not a tool for the job. End up with the Dremel 4300 series in hand. Finish the job likity split. So that now, I just make sure my Dremel 4300 and vast assortment of attachments are with me at every job. Gives me complete confidence that the job will be finished on time and at the highest quality level a perfectionist like myself demands. Can't thank you enough at Dremel for producing the finest rotary tool on the market. Absolutely nothing bad to report about this fine power tool. Great job!!!
