Dottie 620 1 1/4" x 6" Ship Auger Drill Bit

Built for faster, cleaner wood boring, the Dottie 620 auger drill bit is the go-to choice for electricians, low-voltage installers and security technicians. This auger bit features a self-feeding screw point that pulls the bit through wood, cutting down operator effort and speeding repetitive drilling tasks. The 1-1/4 in x 6 in profile and two extension recesses let you reach deep through studs and joists—ideal when fishing surveillance, monitoring or network cables during security system installs.

Manufactured from heat-treated S45C grade carbon steel with aggressive cutting edges, the Dottie 620 bores through tough framing and embedded nails with minimal chatter and long-lasting sharpness. That durability reduces downtime and replacement costs on busy job sites. Designed for professional installers, it produces clean, consistent holes that simplify conduit routing and cable management for CCTV, access control and monitoring equipment.
