Review on 🔧 Steelex M1089 Mill Holder Set - 5 Piece by Dana Mahendra

I'm not a professional machinist and have not used all sizes but the 1/2 I got has 0.8 thousandths mileage that's in the hole is listed . My spindle has less than 0.1 thousandths. The set screw on the 1/2 holder must not be tightened with a standard Allen key. It's located between hexes #5 and #6. The head of the setscrew has a terrible finish. You will need to sharpen a #6 allen wrench to tighten the set screw. It works for my homeshop.
