Bosch PH2 Impact Bits (25 pcs)

These Bosch PH2 impact screwdriver bits are built for trade use, not the occasional weekend job. If you’re running an impact driver all day and snapping through standard bits like they’re made of cheese, these are the answer. Supplied in packs of 25 and stored in a neat tic-tac style box that actually fits in your tool bag, they’re a practical choice for anyone who goes through bits at volume.

The bits are made from S2 modified steel with an optimised heat treatment process, which gives them the toughness needed to handle the rotational force and shock loading that impact drivers produce. A lot of standard screwdriver bits aren’t rated for impact use and will fail quickly under that kind of stress. These are specifically designed for it.

What Makes These Bosch Impact Bits Different

The extended torsion zone is the key feature here. It allows the bit to flex slightly under load rather than transmitting the full shock directly to the tip. That flex absorbs the peak torque spikes from the impact mechanism, which is what causes premature tip wear and bit breakage on non-impact rated bits. The result is a bit that lasts significantly longer in impact driver use without losing its drive shape.

The tic-tac box storage might sound like a small detail, but on site it genuinely matters. Bits stay organised, you can see what you’ve got at a glance, and you’re not digging around a drawer for a loose PH2 at 7am. Available in 25mm and 50mm lengths, both in packs of 25, so you can match the bit length to the application.

For any trade that involves volume screwdriving, whether that’s first fix carpentry, second fix joinery, or general site work, having a reliable stock of quality impact screwdriver bits on hand is just part of the job.
