Stewart Fastener US5-3/8 3/8 Inch Metal Drill Bit

Product Description

The STEWART FASTENER US5-3/8 is a 3/8 inch black metal drill bit designed for use in trade and industrial drilling applications. Built for cutting through metal substrates, this bit is suited for use by electricians, plumbers, HVAC technicians, and general contractors who need a reliable bit for on-the-job metal drilling. The black finish is typical of oxide-coated bits, which provide a degree of corrosion resistance and reduced friction during use. It is sized at 3/8 inch diameter, a common size for conduit knockouts, pipe penetrations, and structural metal work.

This bit is appropriate for use in residential and light commercial settings where metal drilling is required. Common applications include drilling through sheet metal, light-gauge steel framing, electrical enclosures, and HVAC equipment panels. It is intended for use with standard 3/8 inch or larger chuck power drills and drill presses. Tradespeople across multiple disciplines keep this size on hand for routine penetration and fastener prep work.

Installation Notes

This bit should be installed by a qualified tradesperson familiar with metal drilling practices. Always secure the workpiece before drilling and wear appropriate eye protection. Use cutting fluid or lubricant when drilling through thicker metal stock to extend bit life and reduce heat buildup. Ensure the drill is powered off and the chuck is fully tightened before beginning any drilling operation.
