Milwaukee Step Drill Bits Editorial Review
The 3/16 - 7/8 Impact Step Drill Bit #4 is a unibit designed to allow entry into tight places while working with metal. While some customers have noted that the product is not meant for use with an impact driver, others have found it to be the best unibit they have owned. It is noted that the product does not fit well into a 1/4 inch hex chuck and may require filing to be used with an impact driver. In general, customers seem to be pleased with the product's performance.
