Our American-made All-U-Need is a flat lap machine that is one of the best on the market and has been for over 30 years. Grind, smooth and polish rocks and minerals to make free-form shapes and cabochons for necklaces, earrings, rings and other jewelry pieces. Create flats for larger pieces or on the backs of cabochons. It’s also well-suited for polishing a large variety of natural and synthetic gem material, enamels and metals. The All-U-Need is available in both 6″ and 8″ models and comes with an accessory kit specially designed for grinding, smoothing and polishing rocks and minerals. (If you plan on polishing glass and/or crystal, we suggest purchasing the All-U-Need glass/crystal model.)

The Hi-Tech Diamond All-U-Need lap machine is manufactured with a 1/2" arbor and powered by a 1/4 hp, heavy-duty, ball bearing, DC motor. This motor is variable speed so you can work at whatever pace you desire, delivering speeds from 800 rpm to 3,400 rpm. This portable machine can be used anywhere. Whether you're at home, in the shop or on the road, this quiet machine won't disturb others around you. It's lightweight, rustproof and impact-resistant, making it even easier to travel with.

The coolant reservoir, which holds about a pint of water, prevents heat buildup while you work and removes dust particles so you don't inhale any harsh chemicals. That pint of water will give you two to three straight hours of work without refilling. The black splash guard keeps water off you so you don't get soaked while you work. Cleanup is as simple as it gets: Just remove the black spray shield, rinse with clean water and you're ready to work again.

Make sure you choose the right power supply for your machine. The 220 volt models are available only for overseas customers that require 220V - 240V power supply. All 220 volt models are manufactured with this CE rated, Type F plug (see below):

Only one grinding wheel

There’s really only one grinding wheel in this set and that’s 180 grit. The other wheels are smoothing wheels and they have no teeth at all they are totally worthless. There’s no difference between them.. i’m disappointed. I have to get separate additional grinding wheels to make any progress toward polishing. i’m back to using my Glastar

Hi Dean - Thanks for your feedback—we’re sorry to hear you were disappointed. We’d like to clarify that the smoothing discs in the All-U-Need set are not designed with teeth and are not advertised as grinding wheels. They’re intended for the later stages of the process, helping refine and smooth surfaces after initial shaping. The 180-grit disc is the primary grinding wheel included for material removal. It sounds like the tool you needed for your project may require additional or different grinding options. We’d be happy to help you choose the best setup for your application so you can get the results you’re after. Please feel free to reach out to our team directly—we’re here to help.

Works great but have one suggestion

Beginner to rocks polishing and cabbing ... Thank god for you tube ... Either way I like this machine and I am learning to use it to it's full potential. Having a blast. Only thing I would like to suggest is the screws that hold the white catch tray to the top of the machine could use a change. I take the white catch tray off after each use to fully clean it under water. But it is not easy to line it back up with the two small holes and put the screws back in. Bigger screws? A notch to line it all back up? Just something to make it easier to put the tray back on.

Hi Bill - Thanks so much for sharing your experience—we love hearing that you’re having a blast learning cabbing and polishing with the All-U-Need! It’s great to know the machine is helping you grow your skills, and YouTube can definitely be a helpful companion along the way. We really appreciate your thoughtful feedback about the white catch tray. You’re absolutely right—ease of removal and reattachment is important, especially for users who clean it after each session. Your suggestions around larger screws or an alignment notch are helpful and will be shared with our product team for consideration in future design improvements. Thanks again for choosing Hi-Tech Diamond and for taking the time to share your insights. Happy polishing!

8" Flat Lap

As soon as it came in I tried it out right away. The results I got were better than I expected for a first time use. What I like is it is so easy to set up and to change the laps. It is light enough that I can take it out on my lanai when I want to and enjoy the outdoors while using it. I am now looking at purchasing a few different laps to fine tune what my hobby. I am very happy with my purchase.

Had an issue, fixed immediately!

My new all u need flat lap had issues after the first couple uses, I made contact with Hi-Tech, sent them videos anmd my proof of purchase and they immediately responded and took care of me. The product is awesome and the customer service is above and beyond what you typically see these days. If you’ve been contemplating a flat lap, I will be buying from them again and recommend you do as well if you love that shine

Hi Scott - Thank you for bringing this to our attention. We’re sorry to hear about your experience with your new All-U-Need unit. A wobble or hard start is not typical, and we definitely want to help get this resolved. Our support team replied to your email yesterday. We look forward to hearing from you and appreciate the opportunity to assist you.

Works well, seems expensive

My 8” AYN flat lap seems to work well. It was quite expensive for what it is, which is a motor in a plastic housing. Simple but gets the job done.
