Step Drill Bits Plastic Panel are designed to drill plastic panels efficiently without cracking or melting edges. Constructed from high-speed steel or coated materials, they maintain sharp cutting performance for repeated use. Step geometry allows multiple diameters to be drilled in one pass, while tapered or straight shanks provide secure mounting in drill presses, CNC machines, or hand drills. Spiral flutes enhance chip removal and heat dissipation. Ideal for fabrication workshops, prototyping labs, and DIY plastic projects.
