Robert Bosch Tool Group NKST14 Short Auger Bit 7/8 in

Product Description

The ROBERT BOSCH TOOL GROUP NKST14 is a short auger bit designed for wood boring in applications where nails are likely to be encountered. Measuring 7/8 inch in diameter with a 7.5-inch overall length and a 4-inch flute, this bit is built to cut through embedded nails without premature failure. Dual cutting edges balance the drilling action and ease nail cutting. The reinforced tip withstands repeated nail contact, and the reamer edge improves both entry and exit hole quality. Carpenters, electricians, and plumbers use this type of bit when boring through framing, plates, or other structural lumber that may contain fasteners.

The NKST14 is suited for residential and light commercial rough-in work where drilling through wood framing is routine. Its open-faced flute design promotes chip evacuation, reducing clogging during extended boring runs. The 7/16-inch shank fits standard heavy-duty drill chucks and right-angle drills commonly used for in-wall and through-floor drilling. It is a practical choice for trade work where encountering nails mid-bore is expected rather than exceptional.
