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.

Love...LOVE This Machine. Got the 8" Slant Cab. My stuff comes out like GLASS, if you follow thru with all steps. I've had it for 5 months or so, it's so addicting. A Work Horse of a Machine...


The 6 inch lap works really well. Out of the box it does have enough to start and I have been able to get a reflective polish on my first cab. Overall, the machine does run quietly so I am able to use it indoors without much noise pollution.
For my polishing pad tried it dry but I ended up adding a little bit of water to keep my stone cool.

It is a good machine looking to enter into lapidary and I have not had any issues with the machine. I did have to buy the dop kit to save my fingers. It was worth every cent I spent on the machine.

Updated review.

In my original review I said I was having trouble getting a good polish. I have had good results since then.
This machine is well worth the money.
I love this lapidary hobby and my Hi-Tech machines!

Great machine

I have used it for several hours now. Well built just like my 6" saw. I have not been able to get a great polish with the included disks. I plan to mainly use it for shaping and then finish in a tumbler.
Overall a well-built machine. I am happy with my purchase.

Overall a very good product

The system is very easy to use and functional. I haven’t completed any projects yet but I would suggest buying an additional rougher diamond disk because if you’re like me and sometimes do not have the best of cuts this will save you a ton of time. Overall the product is easy to assemble, use and small enough to find a space in the shed for. I recommend!
