Screwdriver impact bits Dedra T10/T15/T20/T25/T30/T40 25 mm, set of 6

Set of six Dedra impact screwdriver bits in Torx sizes T10, T15, T20, T25, T30 and T40, each 25 mm long, designed for use with impact drivers and impact screwdrivers. The bits are hardened to withstand high torque and shock loads, providing reliable engagement with Torx fasteners for assembly, repair and maintenance tasks. Compact 25 mm length makes them suitable for work in confined spaces while maintaining good control and contact between bit and fastener.

Advantages

The Dedra impact bits are manufactured from hardened steel to resist wear and deformation under repeated impact and torque. Precision-machined Torx tips ensure accurate fit and reduced cam-out when driving fasteners. Standard 1/4" hex shank allows quick insertion into compatible holders, impact drivers and bit chucks. The uniform 25 mm length balances reach and stability for both professional and DIY applications.

Suitable for

• Assembly of furniture and fixtures using Torx fasteners
• Automotive repair and maintenance tasks that require Torx bits
• Installation and dismantling of electrical and mechanical components
• DIY projects and general household repairs

Key specifications

• Bit type: Torx (T10, T15, T20, T25, T30, T40)
• Quantity: 6 pieces
• Length: 25 mm per bit

How to use

Select the Torx size that matches the fastener head and insert the 1/4" hex shank into the impact driver or screwdriver chuck until it locks. Apply steady pressure and engage the driver at low speed to seat the bit in the fastener, then increase torque as needed. For removal, reverse the driver direction and keep the bit aligned with the fastener to prevent rounding. After use, store bits in a dedicated holder to protect the tips and prolong service life.

Usage recommendations

Use these Dedra impact bits in tools rated for impact use; avoid using non-impact drivers with severely worn bits. Match bit size precisely to the fastener to minimize cam-out and tip damage. Inspect bits regularly for wear and replace any that show rounding or cracks.
