The DISSTON COMPANY 259517 is a 66-piece screwdriving bit set designed for professional trades use across HVAC, electrical, plumbing, and general mechanical work. The set covers a broad range of drive types, including Phillips, Slotted, Square, Hex, and Torx, in both 1-inch and 2-inch lengths, plus double-end power bits and drive accessories. Bit counts are precise: for example, six Phillips 2 at 1 inch, five Torx 25 at 1 inch, and four Torx 25 at 2 inches. The full assortment is organized in a durable clamshell case that keeps bits sorted and accessible on the job or in the service van.
This set is suited for residential and light commercial service work where a technician needs a wide variety of drive types without carrying multiple sets. The inclusion of 1/4-inch and 5/16-inch magnetic nut setters, a 1/4-inch to 3/8-inch socket adapter, and a 4-inch magnetic drive guide extends the utility beyond standard bit work. Trades professionals installing panels, equipment controls, access covers, and enclosures will find the Torx and Square drive coverage particularly useful for modern fastener configurations.
Designed for use with standard 1/4-inch hex shank power drivers and impact drivers common across HVAC, electrical, and plumbing service applications.
Select the correct bit type and size before driving fasteners to avoid cam-out and fastener damage. Always de-energize electrical equipment before removing cover panels or access screws. Use impact-rated bits with impact drivers; standard bits may fracture under impact torque. Store bits in the provided case to prevent loss and corrosion on the job site.
