Screwdriver Bit Set DeWALT DT7998T-QZ 5 pcs PH 2 50mm Hexagonal

The DeWALT DT7998T-QZ Screwdriver Bit Set contains five PH2 bits, each 50 mm long, with a hexagonal shank designed for reliable engagement with power drivers and bit holders. These bits are manufactured for accuracy in drive fit and tip geometry, delivering consistent screw seating and reduced cam-out during repetitive fastening tasks. The compact set provides a straightforward selection for common Phillips screw sizes used in construction, cabinetry, and general assembly.

Advantages

Each 50 mm PH2 bit features a hexagonal shank for secure retention in chucks and quick-change holders, improving transfer of torque and minimizing wobble. The tip geometry is produced to tight tolerances to enhance contact with screw heads and reduce stripping. The set’s compact five-piece configuration simplifies inventory for frequent use and replacement, while materials and heat treatment provide increased wear resistance for longer service life under typical trade and DIY conditions.

Suitable for

• Fastening and removing Phillips (PH2) screws in wood, metal, and plastic
• Use with cordless and corded drills, impact drivers, and hand bit holders
• On-site construction, carpentry, cabinetry, and furniture assembly
• General household repairs and do-it-yourself projects

Key specifications

• Tip type: Phillips PH2
• Bit length: 50 mm
• Shank type: Hexagonal
• Set quantity: 5 pieces
• Compatibility: Standard 1/4" hex quick-change chucks and bit holders

How to use

Select a PH2 bit from the set and insert the hexagonal shank into the driver chuck or quick-change holder until it locks. Match the bit tip to the screw head, apply steady forward pressure, and operate the driver at an appropriate speed and torque setting to avoid overdriving or stripping the screw head. For manual use, secure the bit in a bit holder or screwdriver handle designed for 1/4" hex bits. Inspect bits periodically for tip wear and replace any bit showing rounding or damage.

Usage recommendations

Use moderate torque and controlled speed when driving screws into hard materials. For impact drivers, ensure the bit is rated for impact use if applying sustained high torque. Store bits in a protective case or rack to prevent tip damage and maintain accurate fit.
