Review on 🔧 Versatile 4SHANK×3 1 Grinded Milling Slotting Tool for Precision Machining by Aaron Schultz

I used this to mill 38° holes in ½" and ⅜" steel. Drilled a total of 40 holes with no problems. After that I was just curious to see how it would work with stainless steel, so I drilled a hole right through the ⅜ inch stainless steel with no chipping or drill breakage. Of course I used Kool Mist coolant. sharp and chip free Needless to say I am very impressed with this racquet and did not expect such quality for the price.
