Review on 🔧 Bosch BL2175 Fractional Reduced Shank: Ultimate Tool for Precision Drilling by Christopher Jackson

I received this drill bit for drilling a few quarter inch holes in a sheet of steel. I couldn't use my drill press due to the size. After drilling a pilot hole and using a dark cutting fluid, this drill exceeded all expectations. This made a perfect 5/8" hole and the bit was still sharp like new. If used properly, this bit should last a long time.
