Precision Twist Drill 015022 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 015022 is a high-speed steel (HSS) jobber-series drill bit engineered for drilling into hard materials where heat resistance and edge retention are critical. With a tip diameter of 0.3770 inches and a depth of cut reaching 4 inches, this bit is suited for through-hole and deep-hole applications across metal, hard plastics, and similar tough substrates. Weighing 0.65 pounds, it is a solid, single-unit tool built for repetitive use in demanding shop and field conditions. Electricians, plumbers, HVAC techs, and general tradespeople rely on HSS jobber bits as a standard drilling tool across a wide range of trade work.

This jobber-length drill bit is appropriate for both bench drill press use and handheld drill applications where a standard-length bit is required. Its 4-inch depth of cut makes it practical for penetrating framing members, metal strut, and thick stock in residential and light commercial installations. Tradespeople who regularly drill through structural material or heavy-gauge metal will find the HSS construction capable of handling sustained drilling cycles without rapid dulling.

Key Features

• High-speed steel (HSS) construction provides heat resistance and durability in hard-material drilling
• 0.3770-inch tip diameter suits a range of standard hole sizes in metal, hard plastic, and similar materials
• 4-inch depth of cut supports through-hole drilling in thick stock and framing members
• Jobber-series length offers a balanced reach-to-rigidity ratio for both drill press and handheld use
• Single-pack unit (minimum order quantity of 1) for straightforward procurement

Compatibility

Designed as a standard jobber-length HSS drill bit compatible with 3-jaw chucks and keyless chucks sized to accept a 0.3770-inch shank diameter on conventional corded and cordless drills and bench drill presses.

Installation Notes

This bit is installed and removed by a licensed or qualified tradesperson using a standard drill chuck appropriate for the shank diameter. Secure the workpiece before drilling to prevent movement, and ensure the drill speed is appropriate for the material being drilled — higher RPM for softer materials, lower RPM for hard metals. Wear appropriate eye protection and follow applicable shop safety practices. Inspect the cutting edges before each use and replace the bit if the tip shows signs of excessive wear or heat damage.
