Step Drill Bit Set for Metal with 9 Sizes TiAlN Coated HSS

Drill clean, accurate holes without stopping to swap bits. This step drill bit covers multiple sizes in one tool, keeping your workflow smooth and efficient from start to finish.

Cut through metal, plastic, and wood with steady control and less effort. Each step delivers a consistent result, so your holes look cleaner and fit exactly as expected.

One Bit That Handles Multiple Hole Sizes with Precision

✅ Drill 9 hole sizes from 1/4 to 3/4 inch without changing bits

✅ Create cleaner, smoother holes with reduced burrs and rework

✅ Start accurately with a 118° tip that reduces slipping

✅ Maintain steady cutting thanks to four-flute chip removal

✅ Cut through stainless steel, sheet metal, wood, and plastic in one setup

✅ Keep momentum on projects with fewer interruptions and faster progress

The step design lets you expand holes gradually, giving you better control compared to standard drill bits. The 118° tip helps the bit stay in position as you begin, so you don’t waste time correcting misaligned holes.

Made from cobalt high-speed steel and coated with TiAlN, the bit handles tougher materials like stainless steel and sheet metal while maintaining consistent cutting performance. The four spiral flutes clear debris quickly, reducing heat buildup and helping each cut stay smooth.

Switch between sizes without stopping your workflow.

Handle multiple hole sizes with one reliable tool.

Coating improves cutting consistency on harder materials.

Four flutes keep chips moving for smoother drilling.

Start holes cleanly with less wandering.

Use across metal, wood, and plastic projects.

Instead of switching between multiple bits, this single tool covers a wide size range, helping you stay focused on the job. It’s especially useful for repetitive drilling tasks or when working with thin materials up to 1/8" (3 mm).

The hex shank fits most standard drills, giving you a secure connection with quick changes when needed. Whether you're working in a home workshop or handling on-site tasks, it keeps things simple and consistent.

Choose the right size range for your project needs.

Adapt to different hole sizes with fewer tools.

Cover common drilling sizes in one solution.

Handle multiple jobs with a single set.

Get clean, precise holes faster without constantly changing bits.
