Robert Bosch Tool Group NKST13 Auger Bit 13/16 X 7-1/2 in

Product Description

The ROBERT BOSCH TOOL GROUP NKST13 is a 13/16-inch by 7-1/2-inch auger bit engineered for wood boring in rough-in applications where embedded nails are a common obstacle. The dual cutting edges balance drilling forces while handling nail contact, and the open-faced flute design clears chips efficiently to maintain consistent feed rate through dimensional lumber, engineered wood, and framing members. A reinforced tip is built to absorb repeated nail strikes without deforming, and a reamer edge improves both entry and exit hole quality to reduce tearout. Licensed electricians, plumbers, and HVAC installers drilling through framing for cable, conduit, or pipe runs will find this bit a practical choice where nail hits are unavoidable.

This auger bit is suited for residential and light commercial rough-in work where trades need to bore through framing, headers, plates, and blocking. The 7-1/2-inch length provides reach through standard framing members without an extension. Its nail-tolerant construction makes it a go-to when working in remodel or retrofit conditions where old nails, staples, and fasteners are embedded in the material. Carpenters, electricians, plumbers, and mechanical contractors running pipe or wire through wood framing will find the NKST13 appropriate for high-cycle, production-style drilling tasks.

Key Features

• Dual cutting edges deliver balanced drilling and easier nail cutting
• Open-faced flute design improves chip removal and reduces clogging
• Reinforced tip withstands repeated nail strikes without tip failure
• Reamer edge improves entry hole and exit hole quality, reducing tearout
• Rated for 9 times longer life compared to standard bits when encountering nail hits

Compatibility

Designed as an OEM-style auger bit compatible with standard 1/2-inch and larger chuck drills and right-angle drill drivers used in wood framing and rough-in applications.

Installation Notes

Installation of this bit is performed by licensed electricians, plumbers, HVAC technicians, and carpenters during rough-in phases. Ensure the drill chuck is fully tightened before operation and that the work piece is secured. When drilling near structural members, follow applicable building codes including NEC and IPC requirements for hole placement and clearance. Inspect the bit tip periodically for deformation, and retire the bit if the reinforced tip or cutting edges show significant wear that affects boring accuracy.
