LSDI LS-84-547 PW36047 Reference Bits, 10-Pack

Save time and avoid costly rework by locating obstructions and measuring through cavities with precision. The Labor Saving Devices LS-84-547 reference bits (10-pack) are purpose-built reference drill bits that let technicians create nearly invisible 0.047" pilot holes to check for knots, blockages or other undesirables before committing to a full bore. Each pack includes ten driver-style bits, and the bit can be trimmed to length for accurate penetration — with a maximum usable length of 36" for deep checks — so crews can probe up through top plates or down from basements through insulation without cosmetic damage. Because the hole is so small it typically requires no refinishing, these bits speed installations for wire pulling, security camera runs, surveillance cabling and monitoring system feeds. Designed for professional contractors, the LS-84-547 helps reduce guesswork, protect finished surfaces and improve first-pass install rates. Keep a pack on the truck for faster obstruction detection and precise measuring on every job — order today to streamline your next security or network install.
