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.)
  • (1) SDH3 Bit (9 steps, 1/4 in. to 3/4 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.

Highly Recommended – Saved Big and Easy Install at 83 Years Old!
Size: CF10134&CA11476
I’ve been taking my cars to my favorite garage for over 25 years, so I trust them completely. When they quoted me $150 just to install and purchase the cabin and engine air filters on my 2016 Honda Accord, I decided to try doing it myself. I bought this Cabin & Engine Air Filter set (fits Honda Accord 2.4L 2013-2017 and Acura TLX) for only about $27 delivered. What a difference in price! Installation was surprisingly straightforward. Everything fit perfectly with no issues. The only extra step was doing a simple factory reset on the control panel, which was very easy and took just a couple of minutes. At 83 years old, I’m proud to say I handled the whole job myself in my driveway. The filters seem high quality, especially with the activated carbon cabin filter. My car runs cleaner now and the air inside smells fresher. Excellent value and perfect fit. If you’re even a little handy, don’t pay the high dealer/garage prices — get this kit and do it yourself. Highly recommended! Would buy again without hesitation.

Perfect Fit & Performance for 2022 Explorer ✅
Size: CA10242&CF12772, Size: CA10242&CF12772
I recently installed this filter set on my 2022 Ford Explorer (2.3L), and I’m very impressed with the results. Both the engine and cabin filters were a perfect fit with no installation issues. Performance & Quality: Solid Build: These feel much sturdier and higher quality than the filters I removed. I bought my vehicle used, and it seems the previous owners used whatever generic parts they could find. These are a noticeable step up. Fuel Efficiency: Since the swap, my MPG has remained rock steady at 26.1 MPG while running 89 octane fuel. It’s good to know the engine is breathing efficiently. Cabin Comfort: The cabin air is noticeably fresh, and the airflow is excellent—no whistling or restricted feel through the vents. Value: Getting both filters in one set is a great deal compared to buying them individually at a local auto parts store or the dealership. I’ll definitely be looking at these again in the next 6 to 12 months for my next maintenance cycle. Bottom Line: If you’re looking for a reliable, cost-effective alternative to dealership prices that doesn't compromise on performance, this is a great choice. See Old vs New Photo

Great value and quality
Size: CF11182&CA12050
Perfect fit for turbo Civic- appears well made. I had an issue with another Honda about 4 days after I changed this and paid $28 for JUST a cabin air filter at an auto parts store. Apparently- mice like to get in there

It's a Filter!
Size: 97133L1000&28113AA100
Fit great! Just look on youtube how to put in! I'm not in a particularly dusty area, but the air cabin filter was a disaster after only a year. Will buy again!
