My Buying Guides on 35mm Step Drill Bit
What I Look for in a 35mm Step Drill Bit
When I shop for a 35mm step drill bit, I first check the material quality. I prefer bits made from high-speed steel or cobalt because they stay sharper longer and handle tougher jobs better. I also look for a clean, precise 35mm step so the hole size is accurate and consistent.
My Priority: Compatibility with My Drill
Before I buy, I always make sure the shank fits my drill. Some step drill bits work better with cordless drills, while others are more suitable for drill presses. I also check whether the bit is designed for metal, plastic, or thin sheet materials, depending on what I plan to work on.

When I’m choosing a 35mm step drill bit, I look for features that improve safety, such as anti-slip shanks and sharp cutting edges that require less pressure. In my experience, a bit that cuts cleanly reduces the chance of slipping and makes drilling more controlled.
