Step and cone drill bits are specially designed for drilling and enlarging holes in sheet metal, plastics, and other thin materials with precision and control. Their unique tapered design allows multiple hole sizes to be drilled with a single bit, eliminating the need to change bits during the job.
Step drill bits feature a series of incremental diameters, creating perfectly sized holes with clean edges, while cone drill bits have a smooth taper for gradually enlarging existing holes. Both designs minimise grabbing, reduce burr formation, and provide a smoother finish compared to standard twist bits.
Ideal for electricians, fabricators, HVAC installers, and metalworkers, step and cone drill bits are commonly made from HSS (High-Speed Steel) and may feature titanium nitride or other coatings to reduce wear and extend life.
