1 Set 6X8MM Head Tungsten Carbide Rotary Burr Set Die Grinder Bit 1/4-Inch Shank Grinder Drill Rotary Burrs Cutting Burs Metal Polishing

Normally carbide bits for steel are super expensive. $40 or more for a single bit. These are a great product and cheap price. The heads were smaller than i had originally thought but the shank was the right size to fit in my die grinder collet and they are holding up great to the abuse I put them through. I plan to buy another set to keep in the drawer when these do finally wear out. But for the price you cant beat the quality of these.

Great product, worked well and value for the money

These are the first cutting bits I've ever bought but they seem to be pretty good. I've used the mainly on steel until the other day I used them on aluminum. I know they aren't made for it but I needed it done. After I finished clogging them up I just simply ran it across some steel to unclog it.

Perfect for the task I had to complete. Great pickup for price.

Great quality and awesome price

At $3.80 a piece the price is hard to beat, but they don't hold-up to steel. Attached is what they look like after being briefly used to clean up some edges the plasma cutter left on mild steel. A big chip is missing from the left burr and several smaller pieces from the right... I guess that's why name-brand carbide burrs that last cost ten times as much! Nevertheless, these should be fine for use on softer metals or wood.

I am lousy with metric measurements so I expected them to be a little bigger but they did the job I needed them for

Exactly what I needed.
