Screwdriver Bit Wiha 33925 Torx T30 90mm 1pc

The Wiha 33925 Torx T30 screwdriver bit is a single 90 mm replacement bit designed for precision fastening tasks. Manufactured by Wiha, this Torx T30 bit offers consistent tip geometry and a straight shank suitable for use with bit holders, quick-change adapters, and powered drivers that accept standard bits. At approximately 20.4 g, it provides a compact, lightweight option for assembly, maintenance, and repair work where access and control are important.

Advantages

The Torx T30 profile delivers secure engagement with corresponding fasteners, reducing cam-out and wear compared with slotted or Phillips profiles. The 90 mm length improves reach into recessed or tight spaces while maintaining tactile control. Precision-machined tip geometry ensures repeatable fit and reduced fastener damage. The hardened steel construction provides durability and resistance to deformation during normal use.

Suitable for

• Automotive assembly and maintenance
• Electronics and appliance repair where Torx T30 fasteners are used
• Furniture assembly and installation tasks
• General mechanical fastening in workshops and construction

Key specifications

• Drive type: Torx T30

How to use

Insert the Torx T30 bit into a compatible bit holder, quick-change chuck, or screwdriver handle. Engage the bit fully with the fastener head to ensure correct seating before applying torque. For powered drivers, start at low speed to seat the bit, then increase speed and torque as required. Withdraw the bit straight to avoid tip damage and inspect the tip periodically for wear; replace if rounded or chipped.

Usage recommendations

Use the bit with appropriately sized Torx T30 fasteners and avoid excessive torque beyond tool and fastener specifications. Store the bit in a dry, secure bit holder to prevent corrosion and mechanical damage. For repetitive or high-torque applications, consider using impact-rated bits and appropriate protective equipment.
