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.

Meh
Color: Black
It's ok. I got it because it looked like it has more cushion and might be more comfortable. Nope. It's the same comfort level as different chairs. My reer still goes numb and gets uncomfortable in this chair. Also, where your arms sit, the chair arms are slightly curved upwards and it causes my chair to be unable to fit under my desk. If they weren't slightly curved, that wouldn't happen. It's just another chair, nothing spectacular.

Solid quality and comfortable
Color: Light Grey, Color: Light Grey
Wonderful quality chair, solid and sturdy, it was easy to put together, the directions were very clear and all the pieces fit together perfectly without issue. It is made of breathable material and I love that the arms flip up easily. You can raise it up or down and it has an adjustable headrest. It also has adjustable lumber support. It rolls easily and the color is the only reason I might return, I think I want a different one instead. The chair is comfortable for a petite person but equally comfortable for a tall person. We have both in our family and it is great for both. The armrests are comfortable and there is really nothing negative to say about this chair at all. Considering the quality, it is a great value for the money.

Comfortable and easy to set up
Color: Black, Color: Black
I’m happy with this chair. It was not hard to assemble, and it feels stable after putting everything together. The mesh back is comfortable and breathable, so it doesn’t feel too hot when sitting for a while. The seat cushion is also thicker than I expected and feels soft enough for daily use. I like the adjustable headrest and the back support, especially for working at a desk. The chair looks simple and clean, and the wheels move smoothly. Good value for a home office chair.
