The Vise Grip UNIBIT-3T is a precision-made step drill bit covering a 1/4" to 3/4" size range, delivering multiple hole sizes in a single tool. Constructed from high-quality hardened steel with a TiN (Titanium Nitride) coating for extended durability and reduced friction during drilling.
Ideal for drilling clean, precise holes in sheet metal, plastic, and thin materials, this step drill bit eliminates the need for multiple bits and deburrs holes as it drills. The hardened steel construction ensures long-lasting performance in demanding MRO and industrial applications.
