Simplify Jobsite Drilling with One Versatile Solution

The Bosch SDH30 3-Piece High Speed Steel Step Drill Bit Set is the ultimate multi-tasking solution for electricians, plumbers, and HVAC contractors. Designed to eliminate the need for carrying multiple drill bits, this set allows you to drill clean, accurate holes in up to 13 different sizes using just a single bit. Whether you are performing electrical knockouts, running conduit, installing faucets, or working on auto body repairs, these bits power through thin materials up to 1/8-inch thick, including sheet metal, ducts, stainless steel, copper, brass, plastic, and even plexiglas.

Engineered for professional performance and longevity, these step drills feature a self-starting point that grabs on contact, preventing the bit from "walking" across the surface. The balanced double-flute design ensures smooth operation by eliminating chatter and vibration, resulting in perfectly round holes every time. Additionally, the bits are equipped with a three-flat shank that locks securely into your drill chuck to reduce slippage under high torque. With re-sharpenable cutting edges, this set provides lasting value and reliability for the most demanding applications.

Key Features

  • Versatile Performance: Drills multiple hole sizes with a single bit, perfect for electrical, plumbing, and HVAC work.
  • Self-Starting Tip: Starts on contact without a center punch and prevents skating on smooth surfaces.
  • Smooth Operation: Balanced double-flute design effectively eliminates chatter and reduces vibration.
  • Secure Grip: Three-flat shank design ensures a tight hold in the chuck and prevents slippage.
  • Long Life: Cutting edges are re-sharpenable to extend the usable life of the tool.
  • Multi-Material Use: Ideal for drilling sheet metal, PVC, wood, veneers, plasterboard, and various metals.

What's Included

  • (1) SDH1 Bit (13 steps, 1/8 in. to 1/2 in.)
  • (1) SDH6 Bit (6 steps, 3/16 in. to 1/2 in.)

Pro-Tip: Step bits generate significant friction, which is the primary cause of dulling. When drilling through metals like steel or stainless steel, always use a cutting lubricant or oil and run your drill at a lower RPM. This keeps the bit cool, preserves the cutting edge, and ensures a cleaner hole.

Good product, poor directions.
Color: Black, Size: B-88''W-4 Panel
The quality of the product was better than most at this price. The directions could have been much better even though I have an engineering background.

Nice partition for my basement
Color: Beige, Size: B-102''-3 Panel
This 3-panel room divider showed up well-packaged with all the parts and even a little tool for putting it together. The instructions were easy to follow, and while one person can definitely assemble it, having two makes it quicker and less frustrating. It does exactly what I needed—gives quick, easy coverage in an open area. I'm using it in my basement to hide the furnace and water heater, and it works great for that. It looks nice overall, but I picked the beige fabric (which is really more of a tan), and the black frame makes it stand out more than I’d like. A white or lighter frame would’ve blended better. Not sure that I would use it anywhere besides the basement It’s lightweight and pretty sturdy. The wheels make it easy to move, but it does get a bit wobbly, and the panel clips need to be readjusted every time you roll it somewhere new. Still, for the price, it’s a solid buy. I’m happy with it and planning to order another one.

Fantastic
Color: Beige, Size: A-132''W-6 Panel
I am perennially in the process of rearranging, reorganizing, getting ready for yard sales, changing the functions of various rooms, moving everything out of a room to do a deep clean, etc, which means that there is always SOME part of my house, if not the entire thing, that is a disaster zone. Having someone knock on my door triggers a "duck and cover" reflex because it's so embarrassing for anyone to see that I live like this. (I *feel* like I don't, really, because I know that all the various stages are all temporary, but when there's always something temporary going on, it might as well be permanent, you know?) So THANK HEAVENS for a room divider that is not only large enough to divide my uncomfortably long den in half the long way so I can shove all the messy parts up against the back wall -- that is not only simple and attractive and neutral and (this is important) NOT BLACK because I have multiple pets and anything black in this house will be pet-hair-colored within 20 seconds -- that not only has **SIX** panels for lots of options of how I want to divide the space/s -- but is also on WHEELS. Someone out there really does love me, it's true! The panels are stable *enough* - I'm not going to lie and say that nothing is going to knock them over, because I have some balance issues, and I also have cats, and both of those circumstances has resulted in a mess on at least one occasion. But in the cats' defense, they've never dealt with a room partition that didn't hang from the ceiling before; and in my defense, I just grabbed the first thing I could reach on the way down. Not the product's fault in either case. Assembly was a little dicey as I am currently in **bilateral** (oh yes, that's fun) wrist braces, so I had to give up until I had help. But I think if you're able-bodied, you shouldn't have any difficulty. The only down side is, now that I've hidden away all the mess so I can break out the holiday decorations, you know what happens next, right?? That's right... the PERMA-MESS ZONE. Oh no. Oh well.

Difficult assembly, doesn’t fold well, looks good fully open
Color: Grey, Size: B-88''W-4 Panel
The instructions for this divider are very inadequate. After having to redo parts of the assembly, I have finally assembled it. The divider itself seems very nice when it is fully open, however it is not possible to fold it well as all the bars with the wheels go in various directions making it impossible to fold it neatly. And it has a large footprint. It is possible that I did not assemble it fully well because of the lack of adequate instructions. I am not even sure if I will keep it because I need to fold out of the way when nothing in use.
