💎 XCSOURCE 6X8MM Tungsten Carbide Burrs: Premium Rotary Drill Die Grinder Carving Bits - Set of 1 for Precision and Efficiency (BI044) Review

Good choice, great metal "punching” tools for various uses. I use mine when making metal sculptures and it cuts through steel like butter. Just make sure to use proper eye protection as it will emit a barrage of sharp, tiny shards of metal that can get into your eyeball very easily. This has happened to me and it's not fun so be careful. I use goggles and a protective mask.

Needed a mild steel drill to lengthen some of the holes, they came in very handy. They appear to be of decent quality although there are some run out issues when mounted in a collet on a grinder. There's nothing a vigorous tightening can't overcome, and the HF collet is probably the problem. The cutting edges are sharp and even, chips fly everywhere. By purchasing Revain, the necessary tooling could be delivered the next day and production could continue. I would buy again.

First discount, products were fantastic! I originally thought they were for a dremel tool, but they fit a drill bit, not a dremel tool (1/8 inch). It worked perfectly for what I wanted so I was very pleased when they arrived. Be careful if you need something smaller, this is suitable for Dremel tools, this is not. They cut metal great, but quite slower when going through really hard metal (I removed a broken screw extractor, super hard metal). were great and never faded. I will be using them…

Bits are hard to keep in position for cutting, this was used with a 90 degree grinder they tend to skip over everything. A very dense and hardened metal, it's tungsten which is why I bought them. My reason for buying was to replace the stage, I wasn't ready to buy a good set of these. I broke one, it snaps hard out of 1/8 inch thick mild steel. I don't blame the product, wrong work for the tool. Perhaps they are better suited for another task? I keep them to myself, there isn't much room in the

It's hard to write a review on something that costs less than 1/4 the price of a good product. However, I don't know what I expected for €15. I bought them to relocate the cylinder head. I have a bat with a really good name and needed the bits to get into smaller areas of the head. They are very sharp and will pierce the cast iron until it comes out of the shaft. They seem very unbalanced at 25000 rpm. The bits bounced off the cast iron and began to vibrate, and at that speed they soon…

I bought these to smooth out some of the welds in the metal sculptures I make to help get into hard to reach places, that an angle grinder cannot achieve. My Grinder is a well known standard name and was easy to work with. They did the job of sanding away rough spots and blemishes where my MIG setup had left some excess metal. If you are trying to get a smooth/nice finish on (carbon) steel, be aware that they leave very visible scratches as they work. As a result, I had to do some polishing in…
