Hertel SD63361737 Step Drill Bit 6-step 3/16-1/2 in Hss

Product Description

The HERTEL SD63361737 is a high-speed steel step drill bit designed to drill multiple hole sizes in a single tool. It covers 6 step sizes ranging from 3/16 inch to 1/2 inch in 1/16 inch increments, with a straight flute and cylindrical shank. The black oxide coating provides mild corrosion resistance and reduces friction during cutting. Made from M2 grade high-speed steel, this bit is suited for general-purpose multipurpose drilling in sheet metal, thin-gauge steel, plastic, and similar materials. It is used by HVAC technicians, electricians, plumbers, and other trade professionals who need clean, sized holes in panels, enclosures, and brackets.

This step drill bit fits standard drilling applications in residential and light commercial trade work. It is well suited for punching sized holes in electrical junction boxes, HVAC sheet metal panels, plumbing access covers, and similar thin-material installations. The quick-change designation indicates compatibility with quick-change chuck systems commonly used in trade cordless drills. The overall length of 1-5/8 inches and 1/4 inch shank diameter keep it compact and easy to control in tight spaces typical of field service work.

Installation Notes

This bit is installed and operated by trade professionals using standard corded or cordless drills. Always secure the workpiece before drilling and use appropriate eye protection. For sheet metal, moderate speed and steady feed pressure produce the cleanest hole with minimal burring. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
