Robert Bosch Tool Group NKST5003 Auger Bit Set 3 Piece

Product Description

The ROBERT BOSCH TOOL GROUP NKST5003 is a 3-piece auger bit set designed for boring clean, accurate holes through wood, even when nails and fasteners are present. The set includes three 7-1/2 inch auger bits in 5/8 inch, 3/4 inch, and 1 inch diameters. Dual cutting edges support balanced drilling and make nail cutting more manageable. An open-faced flute design improves chip evacuation to keep the bit moving cleanly through the work. A reinforced tip is built to withstand repeated contact with nails without premature wear. This set is suited for electricians, plumbers, and carpenters who drill through framing and structural lumber during rough-in work.

This auger bit set is intended for use in wood applications where running conduit, pipe, or wire through framing members is required. The reamer edge at the cutting head improves both entry and exit hole quality, reducing tear-out on the back side of the material. The 7-1/2 inch length provides enough reach for standard framing lumber and light timber work. Trade professionals drilling through stud walls, floor joists, and roof framing will find the three included diameters cover a wide range of common rough-in hole sizes.

Installation Notes

Auger bits of this type are typically used by electricians, plumbers, and general contractors during rough-in phases. Ensure the drill is properly secured and the work material is clamped or braced before drilling. When boring through framing that may contain existing fasteners, reduce feed pressure near the nail to allow the reinforced tip and dual cutting edges to work through without snapping the bit. Follow applicable NEC or IPC clearance requirements when locating holes through structural members.
