Spiral Step Bit #6 1/4" - 1-3/8"

The IDEAL® line of spiral step bits is engineered to save you time and effort with their titanium nitride spiral cutting action. The spiral, dual cutting edge design ensures fast chip removal, less vibration, and a quicker drilling rate, minimizing binding while drilling, making them an economical solution for your projects. Each step is clearly marked with laser engraving and provides gradual relief, easing into cuts and reducing the need to change drill bits. Constructed from M35 high-speed steel with cobalt, these bits offer exceptional strength and durability. Balanced hardened edges and a ¼” hex shank make them compatible with both cordless drills and optimized for impact drivers. The split point tip eliminates the need for a starter pilot hole, minimizing walking on the material for a quick startup. Additionally, the titanium nitride coating lowers cooling time, extending the life of the bit for repetitive drilling through tough materials.

• Average cut time up to four times faster than the competition (based on testing 1-3/8” step drill bit in 1/4” 1008 steel)
• Split-Point Tip provides immediate engagement to minimize walking of the bit
• Spiral Cut - dual cutting edges with continuous cutting action for up to 4X faster cut
• Titanium Nitride Coating lowers the cooling time and extends the life of the bit
• Laser engraving provides clear visibility for step increments
• Impact Rated - makes the bits ideal for impact and cordless drills
• Recommended RPM for step drill bits ≤7/8” 650 RPM, and >7/8” 470 RPM
• Rated up to 8 gauge mild steel, aluminum, copper, brass and plastic
