The Ingco Step Drill Bit 4-22mm (AKSDS04221) creates multiple hole diameters in sheet metal and plastic using one bit. High-speed steel construction maintains edge integrity under high RPM. Titanium coating reduces friction during continuous drilling operations.
This HSS 4341 bit cuts through thin stainless steel, though it works best on softer metals and plastics. Use cutting oil to prevent overheating the titanium coating.
The AKSDS04221 includes 4, 6, 8, 10, 12, 14, 16, 18, 20, and 22mm sizes. Each step is clearly marked for depth accuracy.
