Hougen 35202 Step Drill Bit Cobalt M42 3/16 to 7/8 Inch

Product Description

The HOUGEN 35202 is a cobalt step drill bit designed for drilling multiple hole sizes in a single operation. Built from M42 cobalt high-speed steel, it offers heat and wear resistance suited to drilling steel, stainless steel, and other hard metals. The bit steps from 3/16 inches up to 7/8 inches in 1/8-inch increments, reducing the need to swap bits mid-job. A split point tip starts on contact without a center punch, reducing walking on smooth or coated surfaces. The 3/8-inch round-with-flats shank seats securely in standard three-jaw chucks and most keyed or keyless drill drivers used in fabrication and trade work.

This step drill bit is used in metal fabrication, HVAC, electrical, plumbing, and general trade applications where sheet metal, electrical enclosures, junction boxes, ductwork, or panel steel require clean, accurately sized holes. The stepped profile handles thin to medium gauge materials efficiently, making it a common tool for contractors and service technicians who need a compact, multi-size drilling solution on the job site or in the shop.

Key Features

• M42 cobalt construction for extended tool life in ferrous and abrasive materials
• Drills hole sizes from 3/16 inches to 7/8 inches in a single bit
• 1/8-inch step increments for precise, consistent hole sizing
• Split point tip reduces walking and improves bite on smooth metal surfaces
• 3/8-inch round-with-flats shank prevents slipping in chuck during high-torque drilling

Compatibility

Designed for use with standard 3/8-inch or larger keyed and keyless drill chucks. Suitable for drilling steel, stainless steel, aluminum, and similar metals commonly encountered in HVAC, electrical, and plumbing trade work.

Installation Notes

This bit is installed and used by HVAC technicians, electricians, plumbers, and metal fabricators working with handheld drills or drill presses. Secure the shank firmly in the chuck before operation and use appropriate cutting fluid or oil when drilling hard metals to extend bit life. Always wear eye protection and secure workpieces before drilling. Follow applicable jobsite safety requirements when working near energized equipment or pressurized systems.
