PHILLIPS – Impact Driver Bits – PH2 – No.2 x 90 (1 pcs)

If you have ever snapped a cheap bit mid-drive on a long run of decking screws or structural fixings, you already know why bit quality matters. This 90mm PH2 impact driver bit is built specifically for use with impact drivers, not just adapted from a standard screwdriver bit. The difference shows the moment you put it to work. The 90mm ph2 impact driver bit length gives you better access in awkward positions where a standard 25mm or 50mm bit simply cannot reach.

The metallurgy here has been given proper thought. A heat treatment process is applied during manufacture that targets one of the main causes of bit failure: brittleness at the point of highest stress. Most bit failures happen not because the tip strips out, but because the body cracks or snaps under the rapid torque cycles of a high-powered impact driver. The solution is to reduce hardness at the body slightly so the bit can absorb those peaks rather than fighting them. The tip itself remains hard enough to maintain a clean drive in the recess without rounding.

Where This PH2 Impact Bit Gets Used

That black phosphate finish is not just cosmetic. It gives a degree of corrosion resistance that matters when bits are bouncing around in a van, left out on a wet site, or used with treated timber that can be surprisingly aggressive on bare steel. It also reduces glare, which sounds minor until you are working in direct sunlight and squinting at a fastener.

Length and Access on Site

The 90mm length puts this bit in a useful middle ground. Long enough to reach screws in recessed positions or behind framework, short enough to stay reasonably stable in use without excessive wobble. For anything up to M8 or equivalent self-drilling fixings in timber, plasterboard, or light steel, a PH2 bit at this length is a reliable daily workhorse. Keep a few in your apron and a few in the bag. They go missing at a rate that defies physics.

These bits are sold individually, making them easy to top up without committing to a full box. Available in a range of sizes including PH1 and PH3, in 25mm, 50mm, and 90mm lengths, so you can match the bit to the job rather than making do with whatever is nearest.
