階梯鑽頭 3-12mm | 塑膠鑽孔

Made a bunch of holes for a synth panel mod and each one came out perfectly clean with zero tearing. No need to swap bits constantly, this single tool handled the whole range of diameters I needed.

I needed to make button holes for a synth mod, and this stepped design cut each size cleanly without me swapping bits. The 3-12mm range covers all the small holes I typically drill in plastic enclosures.

Finally, a step bit that doesn't wobble or tear the plastic—the transitions between sizes are super crisp. Drilled a perfect 8mm hole for a new button without any melting or burrs.
