eBoTrade 10 Pieces Tungsten Carbide Rotary Burr SET 1/8"" Shank/double Cut Carbide Rotary Burr Set with 3mm Shank/tungsten Carbide Single Cut Rotary Burr SET 1/8"" Shank Fit Dremel

They work better than my titanium bits! Very durable and perfect size for any drilling component.

Great set! Good for smaller project details. Fits the Dremel well and cut quick. Has little plastic case, and the are sharp. I would get again.

Great little set wolith a nice case.

The flutes are manufactured with precision. The performance is good. The cost for quality reasonable, the only slight negatives are: 1) shafts which are only 3.0 mm. could have easily been made to 3.2 mm for proper collet compatibility and 2) the case is low quality.

This little kit is perfect size for my projects around house, easy to use and pretty sharp. Great deal and price for what you get!

It is a bit smaller than I expected, but I didn't read the review super closely. It does fit my dremel well and will seems durable enough for some small burr work.

Let me give a bit of a disclaimer here, I am NOT a tool & die guy, or an expert on metal working tools. That being said, I do all kinds of DIY projects and crafts. My rotary tool is one of the most used tools I have. Everything from guitar making to sharpening yard tools to shaping wood and metal, these tools seem to be very high quality and very HARD. My specific reason for purchasing this particular set was for working and machining kydex for custom sheaths and holsters. These cutters are AWESOME for that. I have also cut some wood and some sheet steel. Cutters have done well on all that with almost no sign of wear. They are still SHARP. Did I say these things are HARD? They are. Also, there weren't any real measurements of sizes given when I purchased. I was hoping the biggest cutter was 1/4 inch, and it is. So if you look at the biggest cylinder shaped cutter, it is 1/4 inch almost exactly. Everything else is just a little smaller than that. I am VERY HAPPY with this set. Even thought it is Chinese, it seems to be real hard tungsten carbide, and even if it isn't, it is plenty for the tasks I need. Also, arrived in 3 business days, which is fine by me.

I thought 10 burrs for 10 dollars was too good to be true after getting them found out why they're so cheap.The sharks are .005 to .007 undersize which makes them useless in a collet. They might as well be .060 undersize they're useless to me..
