Review on 🔧 Steelex M1089 Mill Holder Set - 5 Piece by Adam Matthews

Used them on my new 30 year old 8x30 imported Knee Mill for 4 months. Have done this in 25 years as a professional tool and die maker. They're no worse than any used American made holders you'll find at any tool and die shop. When I received them they didn't fit in the hole in my car. I searched the internet for R-8 dimensions and tolerances and my car was 0.001-0.0015 smaller. I took a wooden dowel, cut a slit in one end and wrapped sandpaper around it. the other end was inserted into an electric hand drill. Slide it in there and was able to open the hole until they fit and the other collets I bought did fit. After that, these owners earned well. I had no problems with the keyholes - they just fit perfectly. The only thing that annoys me a bit is that two of them had a slightly tightened drawbar. Put a faucet in her and no more problems. Good set for your money.
