Value Collection C87761 7/16 in Jobber Drill Bit Hss

Product Description

The VALUE COLLECTION C87761 is a 7/16-inch jobber-length drill bit designed for general-purpose metal drilling in professional trade and industrial shop environments. Built from M7 high speed steel with a black and gold oxide finish, this bit delivers reliable hardness and wear resistance for repetitive drilling in steel, iron, and similar ferrous materials. The 135-degree split point geometry reduces walking at contact and requires no center punch on most surfaces. The bit measures 5.5 inches overall length with a 4.0625-inch flute length, making it suited for through-hole and deep drilling applications where a standard jobber length is specified.

This drill bit is appropriate for use in stationary drill presses, magnetic base drills, and hand-held electric drills in residential and commercial construction, HVAC fabrication, plumbing rough-in, and general metalworking. It is sold as a single unit and is appropriate for licensed tradespeople and experienced shop technicians who require a heavy-duty jobber bit for production or service work. The right-hand cutting direction and straight cylindrical shank fit standard three-jaw chucks without adapters.

Key Features

• M7 high speed steel construction for heavy-duty drilling in ferrous metals
• 135-degree split point reduces bit walking and lowers feed pressure required at startup
• Black and gold oxide coating provides corrosion resistance and reduced friction during cutting
• Web-thinned, tapered web configuration improves chip evacuation and cutting efficiency
• Regular spiral flute geometry suitable for a wide range of metal drilling applications
• Straight cylindrical shank compatible with standard three-jaw chucks

Compatibility

Designed as a standard jobber-length drill bit for use in any three-jaw chuck or collet system accepting a 7/16-inch straight shank, including stationary drill presses and portable electric drills used in metal fabrication and trade service work.

Installation Notes

This bit is installed and serviced by HVAC technicians, plumbers, electricians, and general metalworkers. Always ensure the drill or press is powered down and the chuck is fully tightened before beginning any drilling operation. Secure the workpiece with a clamp or vise to prevent rotation during contact. Use appropriate cutting fluid when drilling in hard ferrous stock to extend bit life and maintain dimensional accuracy.
