Hertel SDD43275056 Step Drill Bit Set 3 Pc Hss

Product Description

The HERTEL SDD43275056 is a 3-piece step drill bit set designed for drilling clean, stepped holes in sheet metal, thin-gauge steel, plastic, and similar materials. Each bit is manufactured from high-speed steel (HSS) with a bright, uncoated finish and features a split-point tip ground to a 118-degree angle. The split point reduces walking on entry and requires no center punch on flat stock. Maximum drill bit size in the set reaches 30 inches, covering a wide range of hole sizes from a single tool. This set is suited for electricians, HVAC technicians, plumbers, and general metalworkers who need consistent hole sizing without step-down tooling changes.

Step drill bits in this set are appropriate for trade applications involving electrical panel knockouts, conduit entry holes, pipe penetrations through sheet metal, and HVAC equipment cabinets. The inch-measurement system and DIN specification designation align with standard North American trade tooling. The set is packaged as a single unit with a minimum order quantity of one, making it practical for both individual technicians and shop inventory replenishment.

Installation Notes

Step drill bits are installed and used by licensed electricians, HVAC technicians, plumbers, and other trade professionals. Secure the workpiece before drilling and use appropriate cutting speed for the material being drilled. Wear eye protection and ensure the drill chuck is fully tightened before operation. Inspect bits for wear or chipping before each use and replace if the cutting edges are degraded.
