Features and benefits

• SUPERIOR DESIGN. Matco Exclusive Patented Cobalt Hyper-Step set is made from the strongest material tough enough to drill through the hardest jobs like stainless, grade 8 fasteners, hardened alloys and cast irons
• STUBBY LENGTH. Stubby screw machine size which are 1/2 to 2/3 the length of traditional drill bits for increased drill bit rigidity and maximize tight space access
• ELIMINATES THE NEED FOR PILOT HOLES. Patented Hyper-Step design in large sizes eliminates the need for up to two pilot holes that traditional drill bits require
• INNOVATIVE. The multi-stepped tip acts like a step drill, allowing for laser like holes through sheet metal and prevents walking on curved surfaces
• PREVENT FRACTURE. The harder Cobalt drill bit material pairs perfectly with stubby bit lengths to prevent fracture during difficult cordless drilling jobs
• ELIMINATES SLIPPAGE. Three-flatted shanks on both sizes below 3/8" and on the 3/8" reduced shank sizes up to 1/2"
