TORX Impact Driver Bits – TX – Double Ended – TX40 x 65 (2 pcs)

The TORX TX40 double ended impact driver bit is built around one simple idea: stop snapping bits mid-job. If you’ve spent any time with a high-powered impact driver, you’ll know that standard bits weren’t really designed for it. The metallurgy in these bits has been specifically formulated to deal with the violent torque spikes that impact tools produce, rather than just tolerating them until something gives way.

Each bit uses a newly developed heat treatment process that balances hardness in the right places. The tip stays hard enough to grip the fastener properly, while the body of the bit is deliberately softened to flex under load rather than fracture. That’s not a compromise — it’s the point. A bit that flexes slightly is one that doesn’t end up snapped in the head of a screw at 3pm on a Friday.

The black phosphate finish does two things: it reduces glare in bright conditions and provides a reasonable level of corrosion resistance for site use. Won’t survive being left in a bucket of water, but it will handle the usual abuse of a tool belt or site box without rusting up between jobs.

Why Double Ended TORX TX40 Bits Make Sense on Site

Double ended bits are a straightforward win. You get two working ends from one bit, so when one tip finally wears, you flip it and carry on rather than fishing around for a replacement. For TX40 specifically — which sees heavy use in decking, structural timber fixing, and exterior joinery — that extra end pays for itself quickly. The 65mm length also gives you better reach in awkward positions, and enough extension to seat properly in a quick-release chuck without wobbling.

Impact Rating and Compatibility

These bits are rated for impact use, which means they’re suitable for cordless impact drivers from any major brand running at standard torque outputs. They’ll also work in impact wrenches and drill drivers in driver mode. TX40 is a common size across a wide range of construction and outdoor screws, so these will earn their keep on most sites without sitting idle.

Sold in pairs, these TORX TX40 double ended impact driver bits are a sensible buy whether you’re stocking a site kit or just want a backup ready before you need one.
