High speed will lead to fracture of the rod. Different shapes of diamond grinding head show that they got different usages, which makes them different from grinding wheels. The diamond grinding heads are cylindrical, elliptic and conical. The shapes are designed in conjunction with the processing of work piece shapes, which can’t be manufactured by wheels. So when the wheels are not workable, the grinding heads come into use. Still the grinding heads can be used in abrasive grinding features like: grinding, polishing and milling products. We all know that diamond is the one of the most hardest materials, which means the diamond grinding heads have the characteristics like Diamond, so it is often used in high hardness alloy, or non-metal super hard materials. So it’s usages are different and special in comparison with general wheels or other metal wheel of grinding tools.

Product Reviews

better value than Dremel brand and excellent quality

Very happy with these bits. Great price and seem to hold up well. I have used other diamond coated bits to grind down stones and even though I use water with them like you are supposed to, the coating came off way too quickly. I did not have that problem with these. I used one of the cylinders to grind down a large chunk of stone, and after I could barely tell it had been used. impressed.

Just got these bits today to try them out since they were a pretty decent price

I carve a lot of rocks. Just got these bits today to try them out since they were a pretty decent price. Well, I was thrilled with the results. With my other set of bits my rock carvings take about 6 hours each. With these bits, the exact same job took me 45 minutes. Wow. I’ll buy these again.

Does the job!!

This is helping me along marvelously…. the only reason I did not give it five stars was because, it would be so much better with a wider variety of grit on the polishing wheels. Other than that a great product! Fast shipping! Very reasonably priced, as well.You won’t be disappointed.

Work well, convenient case.

Bits/tips are as described, have not damaged yet, enjoying playing with it. Fits in cordless Dremel quite fine. Has been used to shape rocks into raptorial birds and to put holes in stones for pendants.

Great quality at a good price

I have just started to dabble with cutting, shaping, and polishing stones, and this set is great for a novice like myself. The quality of this set, exceeds the small price for it… If you are looking for a great set of stone carving bits, order one for yourself!

Tough product at a reasonable price

I must say up front that I’m rough on my burs because I cut hard stones at high speeds.So I was pleasantly surprised when it took some really pure, unbanded jasper at 35k RPM for over an hour to finally strip some of the diamond coating off of one of the coarser grit drums. Oh yes, it got hot, even with coolant and frequent breaks. But man! It took off a lot of rock.Not bad at all. I’ll probably look to replace these with the same on the future.

Very good service and price

Will do it again. Very good service and price.https://www.amazon.com/dp/B00OJWD9XA/ref=cm_cr_ryp_prd_ttl_sol_20

Great bits for my dremel

Great bits for my dremel. I’m impressed and happy with them. A good value for the price, can’t beat it. The fit fine and they have no problem cutting through stones, rocks and mortar. There’s 44 pieces in the box. They last a long time, after using them to grind mortar all day, you barely notice that the bits were used at all. I would recommend these and would purchase again. They are high quality at a fraction of the price.
