Impact bit Tvardy T40 25 mm S2 — 10 pcs box

Impact bit Tvardy T40 25 mm S2 — 10 pcs box is a set of ten T40 Torx impact bits with a 25 mm working length, manufactured from S2 tool steel. The bits are designed for use with impact drivers and impact screwdrivers, offering high torsional strength and wear resistance for fastening tasks that require repeated high-torque applications. The set is supplied in a compact box for storage and transport.

Advantages

The S2-grade tool steel construction ensures consistent hardness and resistance to deformation under high torque, while the 25 mm length provides a balance between reach and control in tight or recessed fastening positions. Each bit is precision-formed to fit T40 fasteners accurately, reducing cam-out and fastener damage. The ten-piece box simplifies inventory management and allows quick replacement of worn bits on job sites.

Suitable for

• Mechanical assembly and construction fastening
• Installation and maintenance of machinery and equipment
• Work with timber, metal, and composite materials where T40 fasteners are used
• High-torque applications with impact drivers and impact screwdrivers

Key specifications

• Tip type: T40 (Torx)
• Length: 25 mm working length
• Material: S2 tool steel
• Quantity: 10 pieces per box
• Compatibility: designed for use with impact drivers and impact screwdrivers

How to use

Select a T40 bit from the box and insert it securely into the chuck or bit holder of an impact driver or impact-rated screwdriver. Align the bit with the fastener head and apply steady pressure while operating the tool at the appropriate torque setting. Replace worn or deformed bits to maintain precise engagement and reduce the risk of fastener damage. Store unused bits in the supplied box to protect tips and organize inventory.

Usage recommendations

Use with impact-rated drivers only and match the bit type to T40 fasteners. Avoid using excessive torque beyond the tool or fastener limits. Inspect bits regularly for signs of wear or damage and replace them when tip profile or fit is compromised.
