Review on 🔪 Standard Cutting Diameter of Annular JESTUOUS by Jose Schweigert

The cutting set appears well made, sharp and true to size +/- 0.001. good case. I modified the 3/4" cutter holder to use on my knee mill, it works very well. The holes are milled to size and have a reamed surface. Permanent lubrication is required for all core drills designed for internally lubricated magnetic drills, but it works well on my externally lubricated drill. For any use of through holes in the appropriate material, they outperform twist drills in cleanliness and speed, and are much easier than drilling. And the price is right. Okay I'm a hobby shop, have no idea how they stand up to everyday industrial use but they are well made and do the job.
