2.0mm Diamond Drill Bit - 10 Pack (Made in USA)

This is the first time I've used these bits. I've been drilling holes in agates and other gemstones for decades using cheap coated bits that wear out after a few uses. These Lasco drill bits are the best I've had. I always submerge the piece I'm drilling 100% in water and even so, these bits are lasting way longer than anything else I've used. I've already drilled over 30 holes in hard material and have yet to move on to the next bit. The normal cheap bits I used in the past (never again) would often go bad before 10 holes.

was uneasy about the quality of these bits based on a few negative reviews. i expected to only get a few holes out of each bit but i must say i am absolutely blown away these arent just ok there great, spectacular to say the least. i bought dremel brand drill bit and got about 3 holes out of it and it was shot, with just one these ive drilled about 50. i payed 26 dollars for that, do the math, these are a bargain. remember proper cooling and patience is key to drilling clean holes, i use ice water and only drill for about 5 seconds pause and so on. will be buying alot more!

I recieved the product in a timely manner. In fact, it came earlier than expected. the tips on the other hand i didnt quite get what i was expecting. this isnt a bad review, but i was expecting the bit to be more new looking. They looked like they came from the floor of grampas shed with burn and char marks on the shanks. Dont get me wrong.. they did the job. But when I got them I saw them, and had my doubts as to whether they would hold up. All in all it was a good transaction and if I need more I will be back.

These bits are awesome. I was using diamond drill bits from my local Staind glass store and they were useless, they wore out so quickly. The drill bits from Lasco are only a few dollars more and you get 20, not just one! They are fantastic. I've had them for a month and I am still using g the same drill bit and I'm a stained glass artist s I use it a lot on my drill press. I highly recommend these to everyone. I will not buy anywhere else ever again. Thanks for a great product Lasco.

These bits are OK. When using them for glass, it is hard to start the whole because the bit is flat. The bit wobbles until a hole starts, accuracy suffers. I drilled 8 holes in fused clear glass before I thought the cutting efficiency went way down.Under a magnifier I could really tell the difference between a used and a new bit.Would I buy again?, I'll look around first.

Very disappointed .. not made in the USA as stated, made in China. Don't work to drill glass. I would not give it any stars.

Wish this came in 2.03 mm for 2.5mm taps. Otherwise, this works really well for drilling carbon fiber.
