Robert Bosch Tool Group NKST07 Auger Bit 7/16 X 7.5 Inch

Product Description

The ROBERT BOSCH TOOL GROUP NKST07 is a 7/16-inch by 7-1/2-inch auger bit engineered for wood boring in applications where embedded nails are a routine hazard. Marketed under the Daredevil Nail Killer line, this bit features dual cutting edges for balanced drilling and cleaner cuts through fasteners, an open-faced flute design that accelerates chip evacuation, and a reinforced tip built to absorb repeated nail impacts without failure. A reamer edge improves both entry and exit hole quality, reducing tearout on finish and rough framing work alike. Licensed electricians, rough-in carpenters, and electrical contractors driving wire through framed walls will find this bit a practical daily-use tool.

The NKST07 is suited for residential and light commercial rough framing, electrical rough-in, and plumbing penetration work where lumber contains nails, staples, or other embedded fasteners. Its 7-1/2-inch length provides adequate reach for single-stud boring without an extension. The 7/16-inch diameter is a common size for wire and cable passage holes in wood framing. This bit is sold in a package quantity of 60 units, making it appropriate for stocking a service truck or shop supply cabinet.

Installation Notes

Installation is performed by electricians, plumbers, and carpenters during rough-in phases. Ensure the drill is fully powered off and the bit is secured in the chuck before operation. When boring through walls or floor assemblies, confirm the path is clear of live wiring, gas lines, and plumbing before drilling. Inspect the bit tip for deformation after repeated nail contact and replace if the tip is visibly damaged.
