Also known as knockout punches or speed punches, these stud-driven hole punches can quickly make large holes in thick or hard material. Smaller stud-driven punches are typically manually driven with a compatible ratcheting wrench, and larger stud-driven punches can be driven with a compatible hydraulic- or battery-powered driving tool.
Punch different sizes of holes in a variety of materials using these punch sets. They contain a punch, a stud, and multiple dies of different sizes.
Dual: Battery & Hydraulic-Powered
Triple: Manual, Battery & Hydraulic-Powered
Attach one of these punches to a ratcheting wrench or a compatible battery- or hydraulic-powered driving tool. Commonly used for cutting round or D-shaped holes in sheet metal.
Use these draw studs with your stud-driven hole punches to increase the versatility of your tool.
