Product Description

The DISSTON COMPANY 256121 is a 52-piece assorted impact bit set designed for trade professionals who need a broad range of driver bits in a single organized kit. The set covers the most common fastener drives encountered in HVAC, electrical, and general mechanical work, including Phillips, square, Torx, slotted, and hex profiles in both insert and power bit lengths. Titanium Red Helix drill bits in four sizes round out the kit. All pieces store in a molded plastic case that keeps bits sorted and ready for field use. The set is suited for use with impact drivers and standard power drills.

This kit fits residential and light commercial service work where a technician needs a single carry-all for a wide variety of fastener types. The assortment covers panel screws, equipment mounting hardware, and junction box fasteners common in HVAC and electrical installations. The plastic case keeps the set organized in a tool bag or van shelf. The mix of insert bits and longer power bits accommodates both tight-clearance work and extended-reach applications on the same job.

Installation Notes

Select the correct bit profile and size before driving to avoid stripping fastener heads. When using an impact driver, confirm the bits are rated for impact use before applying full torque. Store bits in the provided case after each use to prevent loss and protect cutting edges. No special tools or codes apply to bit set use, but follow all applicable safety practices for the power tool being used.
