SI FANG Mini Pneumatic Chamfering Tool with Replace Blades Inserts and Bearings, 45 Degree Air Chamfer Deburring Tool, Portable Chamfering Machine for Metal C0.1-2/R1.5 Angle Quick Trimming Beveling

Great replacement cutters.

I read the reviews both positive and negative. Seems to work as advertised for me. Make sure you are not supplying more than 6 bar (about 90 psi) to the tool, use a regulator to be sure, it mentions that in the instructions that nobody usually reads. Also knowing what I do about metal working, I feel like some folks may be using the tool far too aggressively causing the damage I've seen described. So far I've had satisfactory results on mild steel and aluminum. My personal opinion is that I would avoid stainless steel or hardened steel. I will update this review if anything changes in my opinion.

I was hoping to find an aircat version of this but the reviews were well enough that I decided on it. The air inlet has a wire mesh filter which I take as a sign of quality in an air tool. The tool comes with all the tools I need to service it. Word of advice if you have big fingers this may be an annoying tool for you. It's quite small and definitely the smallest air tool I own. The parts and tools are equally tiny but that does not make it unusable. I tested it out on the back of a brake pad to see how well it cut and it definitely does what it's intended to do. Plus, the height adjustment markings are very helpful.

Hooked this up to a swag chamfering table on a foot pedal. Works great Fast delivery. Great to do business with.

Normally don't write reviews but this tool really impressed me. I was skeptical of this holding up to the abuse for the price point but it performs very well and seems of decent quality. Only issue I had was the pilot bearing bolt backing out on me once, however I caught in time before it gouged my work. For chamfering the outside edge of a 4x8 sheet and doing close to 1,200 holes I would say it's a win, I only had to flip the cutting edges once during this project. Only reason I only give 4 stars is that additional screws aren't supplied with the replacement blades, they are small enough you can easily drop and lose them during carbide changes. Same goes with the pilot bearing bolt. I measured and got some ordered for the future but they should be included.
