Irwin IR63907 Hss Drill Bit 7/64 in Jobber Length Tin Coated

Product Description

The IRWIN IR63907 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. The bit measures 7/64 inches in diameter with an overall length of 2.625 inches and a flute length of 1.5 inches. A titanium nitride (TiN) coating reduces friction and extends tool life compared to uncoated HSS bits. The 135-degree split-point tip self-centers on contact, reducing walking and the need for a center punch on flat surfaces. Hardness is rated at 80 HRC, giving the bit good edge retention under repeated use. Installers, electricians, plumbers, and general tradespeople rely on this bit for everyday fastener and pilot-hole work.

This drill bit suits a wide range of trade applications where a compact, standard jobber-length bit is required. The 7/64-inch diameter is commonly used for pilot holes in sheet metal, light structural steel, hardwood, and plastic enclosures. The jobber-length geometry fits standard three-jaw drill chucks on corded and cordless drills. It is appropriate for residential and light commercial service work where a durable, coated HSS bit is preferred over a bare steel option.

Installation Notes

This bit is installed and used by electricians, plumbers, HVAC technicians, and general tradespeople performing drilling operations on the job site or in the shop. Secure the bit fully in the chuck before operation and verify the chuck is tightened. Use appropriate cutting fluid when drilling harder metals to manage heat buildup. Inspect the cutting edges before each use and replace the bit if the tip shows signs of dulling or coating wear.
