Klein Tools Double-Fluted Step Drill Bit Set - #15 7/8" to 1-3/8" & #11 7/8" to 1-1/8" Hex Shank, 3 Hole Sizes

This Klein Tools step drill bit bundle includes two double-fluted step drill bits that provide faster, cooler, and more precise drilling compared to single-flute bits. The first bit offers hole sizes ranging from 7/8" to 1-3/8" while the second bit ranges from 7/8" to 1-1/8". Both feature high-visibility silver targets for easy hole size identification and a thick 3/8" hex shank for a secure grip that prevents spinning. With two flutes, these durable bits deliver smooth, accurate holes across various materials like steel, wood, plastic, and aluminum. Their fast-starting, non-walking tip allows for professional results. Together in one bundle, these bits complement each other by covering a wide range of hole sizes. The smaller bit handles general drilling needs up to 1-1/8" holes while the larger bit tackles heavy-duty tasks requiring holes up to 1-3/8".
