High-Performance Hole Making: Diablo 7/8" to 1-3/8" 15-Step Impact Step Drill Bit

The Diablo DSD1375S15 Step Drill Bit brings game-changing technology to Electricians, Plumbers, and HVAC contractors who require speed, precision, and extreme durability in thin metals, PVC, and various plastics. Featuring an innovative 132-degree Split Point Tip, this bit eliminates the need for pre-drilling or pilot holes, providing a fast, "on-point" start that resists bit walking. This advanced design, combined with an automated precision CNC grinding process, ensures strict angle tolerances on every step to deliver 2X faster cuts and up to 6X longer life compared to standard step bits.

Engineered for maximum jobsite efficiency, this 15-step bit is optimized for both corded and cordless tools, allowing for up to 75% more holes per battery charge when used in high-speed mode. The optimized dual-flute design ensures jam-free performance and superior chip removal, while the increased step heights for common hole sizes make drilling more efficient than ever. With a 3/8-inch shank featuring three flats, you can count on maximum stability and zero shank slippage in your drill chuck, even under high-torque applications. Laser-etched markings provide easy-to-read identification for all 15 steps, ensuring accuracy throughout the life of the tool.

Key Features

  • 6X Longer Life: The 132-degree Split Point Tip stays sharper longer and eliminates the need for pre-drilling.
  • 2X Faster Cuts: Automated Precision CNC Grinding delivers exact tolerances for minimal wear and rapid hole making.
  • Cordless Efficiency: Optimized design provides up to 75% more holes per battery charge in high-speed tool modes.
  • Anti-Slip Shank: 3/8” shank with 3 flats prevents bit slippage for increased safety and stability.
  • Jam-Free Drilling: Dual flute architecture is optimized for smooth, jam-free cuts and fast material evacuation.
  • Laser-Etched Markings: Easy-to-read, permanent laser markings for 15 different hole sizes ranging from 7/8" to 1-3/8".
  • Increased Step Heights: Designed specifically for common hole sizes to increase drilling speed and efficiency.

Very spacious and beautiful
Size: 23.6 Inch, Color: White, Size: 23.6 Inch, Color: White
A lot of my books fit on here and there’s still more room left if I wanted to buy more books. It’s a simple looking bookshelf but it’s really pretty. It’s also sturdy the only reason I gave it a 4 stars instead of 5 was because it comes with its own plastic screw anchors and they are crap. The shelves were wobbly when we installed them using the plastic screw anchors that came with the packaging. My dad set mine up and luckily he had a bunch of his own so he switched them out with better screw anchors. Once we made that switch it was perfect, there was no wobble or shaking at all. So that’s my only piece of advice. Besides for the screw anchors everything else is perfect

Super easy to install. I use different wall anchors. The anchors like all anchors that come with shelves are not great. The shelves look very clean on the wall.

This product exceeded my expectations. The installation process was incredibly straightforward—even for someone with little to no experience—and the instructions were clear and easy to follow. Once installed, it feels very sturdy and secure, with no wobbling or shifting at all. You can tell it’s well-designed and made with quality materials. I also appreciated how quickly I was able to set everything up without needing any extra tools or help. Overall, it’s a reliable, user-friendly product that I would absolutely recommend to anyone looking for something dependable and easy to install. Drill is required though.
