Screwdriver bit DeWalt DT7993T-QZ, 25 mm length, pack of 5

DeWalt DT7993T-QZ screwdriver bit set includes five 25 mm bits designed for use with compatible screwdrivers, power drivers and standard bit holders. Each bit features standard geometry for driving screws in assembly, maintenance and repair tasks. The compact 25 mm length is suitable for confined fastening points and portable tool kits, allowing access into shallow recesses while keeping overall tool length short.

Advantages

These 25 mm screwdriver bits are heat treated and made from shock‑resistant tool steel with a hardened core to resist breakage and wear, offering longer bit life in repeated use. The precision tip geometry reduces wobble and minimizes the risk of rounded screw heads, while controlled movement under torque helps maintain stable engagement with fasteners.

Suitable for

• Assembly of furniture and fixtures in confined spaces
• Maintenance and repair tasks with handheld drivers and compact power tools
• Workplaces and tool kits where short bits improve access and portability

Key specifications

• Set contents: 5 screwdriver bits, each 25 mm length
• Material: shock‑resistant tool steel with hardened core
• Tip geometry: standard profile for reliable screw engagement
• Surface treatment: heat treated to resist wear and breakage
• Maximum angular play: less than 4° movement under load

How to use

Select the appropriate bit from the set and insert it into a compatible screwdriver, bit holder or quick‑change chuck. Ensure the bit seats fully in the holder before applying torque. Use steady pressure and a controlled speed to engage screws; for recessed or confined fastenings the 25 mm length allows closer clearance while maintaining effective drive control. Replace bits when wear or tip deformation is visible to avoid damaging screw heads.

Usage recommendations

For best results, match the bit tip to the screw head size, avoid excessive torque beyond the tool’s rating, and inspect bits regularly for wear. Store bits in a dry case to prevent corrosion and maintain tip accuracy.
