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.

Make your cat happy
Color: Pink Cat, Size: Medium (27'' X 20'' X 0.3''), Number of Items: 1
My cat loves this. She was always moving from spot to spot looking for a cooler place to lie. When I put this pad down, she got on it and stays there for long periods of time. The pad is actually cooler than I thought it might be. Good product.

Cool to the touch.
Color: Green Leaf, Size: Small (20'' X 16'' X 0.3''), Number of Items: 4
If definitely feels cool to the touch although still have doubts about ability to cool my dogs. I have not trained my dogs to lay on it so I’m not sure if they know how to use the cooling pads but I do see my one dog lay on it from time to time so perhaps it is effective, not sure. Cooling pad slips and it folds ups because there is no grip on the bottom side. It feels smooth and soft to the touch because of the fabric on the outside. I plan on brining it in my dog stroller in the summer and should be better than having no cooling pad. Although not as cool as an ice pack, this cooling pad doesn’t require refrigeration and always stays cool to the touch and no condensation. Not sure if it’s worth the money for the price because not sure if it works. A four pack for $32 seems reasonable but not sure if it’s worth it.

A summer cooling mat full of endless possibilities! Kitty 🐈‍⬛ imagination highly required! It’s apparently somewhat better than a large empty Amazon box! Beau highly recommends it! ****Review annotated by Beau’s mom Beau’s mom actual review: I purchased the medium sized cooling mat for my chunkster grey tux Beau who at first snoop, didn’t like it. After carefully flopping him on top of it and made stupid sounds, he inevitably decided to actually try it his way thus (while not a box) liked it. I was surprised that after two weeks the mat was still cool and scratch-free from his murder mittens. While he does flop on the mat from time to time, he enjoys dragging it, flipping it in a viscous cycle of who-knows what the heck is going on his mind! Either way, if I could give it 9/10 stars I would as the instructions fails to inform user of a highly kitty imagination is required. No worries tho! Beau figured this out two days into flopping on top of it.

Does not stay cool
I bought this for my bunny and the material itself does feel cool at first. My bunny wast laying on it for about 30- 40 minutes and it feels warm to the touch. So while it does feel cool initially, if your pet is warm the pad will get warm as well. I'd recommend leaving the fan on for your pet in addition to the pad or placing a frozen water bottle on the pad so it keeps the pad cool a little longer.
