Milwaukee Electric - 10PC. Shockwave Impact Duty Carbide Hammer Drill B

Heavy Duty - The Automatic Center Punch is made from steel that resists corrosion. The 18C model is capable of striking a much heavier blow that other sizes. | Automatic Mechanism - The Starrett Center Punch has an internal mechanism that automatically strikes a blow when downward pressure is applied, making it easy to use in any workshop application. | Adjustable Force - The force of the blow can be adjusted when used for different materials by turning the knurled cap. With this setting, it can create a perfect mark on any surface. | Precision Marking - The spring tension which regulates the blow provides a constant point with each strike, ensuring uniformity in depth and size for each setting. This makes it the perfect tool for precision marking. | Wide Range of Application - This tool can help you make a small indentation to accurately spot the location of a hole in metals, plastics, wood, and other machinable materials.
