Precision Twist Drill 015008 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 015008 is a high-speed steel (HSS) jobber-series drill bit built for drilling into hard materials where heat resistance and edge durability matter. With a 0.2660-inch tip diameter and a 4-inch depth of cut, this bit handles a wide range of through-hole and deep-hole drilling tasks on ferrous metals, hardened plastics, and similar tough substrates. The HSS construction maintains cutting hardness at elevated temperatures, reducing the risk of premature edge failure during sustained drilling. Electricians, plumbers, HVAC technicians, and general trade mechanics rely on jobber-series bits as a standard tool for structural and rough-in drilling applications.

This bit is suited for use in standard drill presses, hand drills, and right-angle drills across residential and light commercial job sites. The 4-inch depth of cut and 0.2660-inch diameter make it a practical choice for drilling through wood framing, sheet metal, conduit knockouts, and similar trade-service materials encountered during installation and service work. It is sold as a single unit with a minimum order quantity of one.

Key Features

• High-speed steel (HSS) construction resists heat buildup during hard-material drilling
• 0.2660-inch tip diameter for precise, consistent hole sizing
• 4-inch depth of cut accommodates through-drilling on thick stock and structural members
• Jobber-series length profile compatible with standard three-jaw chucks
• Suitable for ferrous metals, hardened plastics, and similar hard surfaces

Compatibility

Designed as an OEM-style jobber drill bit compatible with standard three-jaw drill chucks in corded and cordless drills and bench-top drill presses commonly used in HVAC, plumbing, and electrical trade applications.

Installation Notes

Installation of drill bits should be performed by qualified trade professionals following applicable job-site safety protocols. Secure the bit fully in the chuck and confirm it is centered before operation. Always wear appropriate eye protection and secure the workpiece before drilling. Reduce feed pressure when the tip begins to break through the back face of the material to prevent bit grab or workpiece movement.
