Robert Bosch Tool Group NKLT20 Auger Bit 1-1/4x17 in

Product Description

The ROBERT BOSCH TOOL GROUP NKLT20 is a 1-1/4 inch by 17 inch auger bit engineered for wood boring in applications where embedded nails are a constant hazard. Part of the Daredevil Nail Killer line, it features dual cutting edges that balance drilling force while handling nail contact without deflecting or binding. The reinforced tip is built to withstand repeated nail hits, and the reamer edge improves both entry and exit hole quality. Framing crews, rough-in electricians, and plumbers working through existing framing will find this bit suited for high-volume production drilling where nail strikes are unavoidable.

This auger bit is designed for use in residential and light commercial construction and renovation work, particularly in situations requiring drilling through dimensional lumber, engineered wood members, or reclaimed framing stock that may contain hidden fasteners. It is compatible with standard hex-shank or auger-compatible drill chucks. The 17-inch length provides adequate reach for drilling through double plates and thick framing members without extensions. Package quantity is 10 bits per unit.

Installation Notes

Installation and use of this bit should be performed by qualified tradespeople including electricians, plumbers, or carpenters performing rough-in work. Operator should wear appropriate eye and face protection, as nail contact can produce metal fragments. Ensure the drill driver is set to an appropriate torque and speed setting for the material being bored. Inspect the bit for wear or damage before each use, particularly after known nail strikes.
