This versatile 9-step configuration covers diameters from 4mm to 20mm in 2mm increments, making it the ideal choice for general metalworking, electrical enclosures, and plumbing applications. The 75mm overall length provides an excellent balance between control and reach, whilst the 65g weight offers substantial rigidity for accurate drilling without excessive bulk. Designed for high accuracy drilling in sheet materials up to 3mm thick, this step drill bit efficiently creates holes for cable glands, pipework penetrations, and mounting hardware.
The 2mm step increments provide commonly-used hole sizes whilst maintaining strong step edges for clean cutting performance.
