Ideal Industries Step Drill Bit 1/8" - 1/2" with Titanium Nitride Coating and Double-Fluted Design

Professional precision drilling with extended bit life and balanced performance

The Ideal Industries Step Drill Bit delivers professional-grade performance for electrical and general drilling applications. This precision-engineered bit features a unique double-fluted design that ensures balanced cuts and cooler operation, while the titanium nitride coating dramatically extends bit life. With its 1/8" to 1/2" range and split-point design for faster starts, this step drill provides reliable performance for creating multiple hole sizes with a single bit.

Professional Features & Benefits

  • 1/8" - 1/2" Size Range: Single bit handles multiple hole sizes, reducing tool changes and improving efficiency on the job site.
  • Titanium Nitride Coating: Dramatically extends bit life by providing superior wear resistance and heat dissipation for long-lasting performance.
  • Double-Fluted Design: Ensures balanced cuts and cooler operation by providing efficient chip evacuation and reduced heat buildup.
  • Split-Point Design: Enables faster starts with reduced walking and improved accuracy when beginning holes.
  • 1-Inch Shank Length: Provides optimal grip and stability in standard drill chucks for secure operation.
  • Professional Grade Construction: Built to withstand demanding electrical and construction applications with consistent performance.

Installation & Operation

  1. Mount the bit securely in a suitable drill chuck, ensuring proper tightening and alignment for safe operation.
  2. Connect the drill to appropriate power source and verify proper chuck engagement before beginning work.
  3. Position the split-point tip at the desired drilling location and apply steady, controlled pressure to start the hole.
  4. Configure drilling speed according to material type and thickness, maintaining consistent feed rate for optimal performance.
  5. Test hole size progression as the step drill advances, stopping at the desired diameter marking on the bit.
  6. Complete the drilling operation and clean the bit of debris before storage or next use.

Ideal Industries 35-511 – Frequently Asked Questions

1) What hole sizes can the Ideal Industries titanium nitride step drill cover?
Five cutting ranges are offered across the Ideal step drill line: 1/8 to 1/2 inch (35-511), 1/4 to 3/4 inch (35-512), 1/4 to 7/8 inch (35-513), 1/4 to 1-1/8 inch (35-515), and 1/4 to 1-3/8 inch (35-517). One bit steps through several diameters, so you are not swapping bits to open a hole up.
2) Which Ideal step drill do I need to punch a hole for 1/2 inch trade size conduit in a panel?
For 1/2 inch conduit the knockout hole is 7/8 inch, so the 35-513 (1/4 to 7/8 inch) is the smallest Ideal step drill that will get you there; the 35-515 and 35-517 also pass through 7/8 inch on their way up. The 1/8 to 1/2 inch bit (35-511) stops short and will not open that hole.
3) Will this step drill fit a standard cordless drill chuck?
The shank is 1 inch long and seats in a standard drill chuck, so a common 3/8 or 1/2 inch keyless chuck holds it. Tighten fully and check alignment before you run it, since a step drill is cutting off-center loads as it steps up.
4) Is a step drill better than a hole saw or a knockout punch for cutting enclosure holes?
A step drill is the right call for thin material, sheet metal, panel and enclosure walls, and duct, where one bit gives you a range of sizes and you stop at the diameter you want. A knockout punch is cleaner and faster if you are making the same large hole repeatedly in heavier gauge, and a hole saw makes sense above the step drill's top size. The Ideal step drills top out at 1-3/8 inch on the 35-517, so anything larger than that needs a different tool.
5) I need a single step drill for general electrical rough-in. Which range covers the most common holes?
For mixed conduit and cable entry work, the 35-517 (1/4 to 1-3/8 inch) covers the widest span in one bit, taking in 7/8 inch for 1/2 inch conduit and 1-1/8 inch for 3/4 inch conduit knockouts. If your work stays small, the 35-511 (1/8 to 1/2 inch) handles the fine end that the 1/4 inch starting bits cannot reach.
6) What does the titanium nitride coating actually do on a step drill?
The TiN coating adds wear resistance and helps shed heat, which is what keeps the cutting edges alive when you are stepping through sheet metal repeatedly. Paired with the double-fluted geometry, which clears chips and runs cooler, it is aimed at bits that see a lot of enclosure and duct work rather than occasional use.
7) Does this bit walk when starting a hole on smooth sheet metal?
The tip is a split point, which bites in faster and reduces walking when you start a hole, so you can often skip the center punch on sheet stock. Position the tip, apply steady pressure, and hold speed to suit the material.
8) Can I read the hole size off the bit while drilling?
Yes, the steps are marked by diameter, so you advance until you reach the marking for the size you want and stop there. That is how you get multiple hole sizes out of one bit without measuring the hole afterward.
