Is there a way to adjust the spring pressure on the Delta Kits spring hammer?
No, the spring hammer is pre-set for optimal results when matched with Delta Kits 26020 Carbide Bur. Using the correct drilling bur, drilling technique, drill hole depth, and drill hole placement, are paramount to long crack termination success. Note that the spring hammer depth gauge indicates the "minimum" drilling depth for optimal performance. Please watch our spring hammer instructional video, then practice drilling to different depths and popping bullseyes until you get the desired consistent results.
