DeWalt impact screwdriver bit set DT70537T — 2× T20 bits, magnetic holder

DeWalt impact screwdriver bit set DT70537T includes two T20 Torx impact-rated bits and a magnetic holder designed for use with impact drivers and compatible drills. The bits are manufactured to withstand high torque and repetitive fastening, making them suitable for assembling structures and installing fasteners in wood and metal where increased durability is required. The magnetic holder enables quick bit changes and secures the bit during operation to reduce wobble and improve engagement with screw heads.

Advantages

The impact-rated T20 bits resist deformation and chipping under high torque compared with standard bits, extending service life in professional and DIY applications. The magnetic holder provides stable retention of bits, enabling faster workflow and safer handling when changing or transporting bits. The compact set contains the most commonly used Torx size for many construction and maintenance tasks, reducing the need to swap to different bit types during a job.

Suitable for

• Fastening Torx T20 screws in wood framing and cabinetry
• Installing metal fasteners where higher torque is required
• Assembly and disassembly tasks with impact drivers or drills
• Construction, maintenance, and workshop tasks requiring durable bits

Key specifications

• Bit type: T20 Torx impact-rated screwdriver bits
• Quantity: 2 bits plus 1 magnetic holder
• Compatibility: Designed for use with impact drivers and drills that accept standard bit holders
• Material/treatment: Hardened steel for high torque applications (impact-rated)
• Retention: Magnetic holder for quick changes and stable engagement

How to use

Insert a T20 bit into the magnetic holder until it seats securely, then insert the holder into the chuck or quick-change collet of an impact driver or drill. Position the bit into the Torx screw head, apply steady pressure, and operate the tool at appropriate speed and torque settings for the material. For removal, reverse the tool direction and hold the tool steady to prevent cam-out. Store bits in a dry place after use to avoid corrosion and inspect before each job for wear or rounding.

Usage recommendations

Use the DeWalt T20 impact bits with an impact-rated driver and matched torque settings to maximize bit life. Replace bits that show significant wear or mushrooming at the tip. For precise work, start at lower speeds and increase torque only as needed; when working with metal screws use lubrication if recommended for the fastener to reduce heat and wear.
