PHILLIPS Impact Driver Bits – PH – Double Ended – No.3 x 65 (2 pcs)
£2.45£2.94 EX VATINC VAT
Double ended PH3 impact driver bits, 65mm long and sold in a pack of two. Built to handle the torque peaks of high-powered impact tools, with a heat-treated body and black phosphate finish for corrosion resistance.
The 65mm PH3 double ended impact driver bit is one of those things you don’t think about until the one in your driver snaps mid-job. These bits are designed specifically for impact drivers, not just repurposed standard bits with a hopeful attitude. The double ended format means when one end gives up, you flip it round and carry on. Simple.
Impact driving puts a completely different kind of stress on a bit compared to a standard drill driver. The rotational torque comes in rapid peaks rather than a steady load, and that’s what destroys ordinary bits. These have been through a specific heat treatment process that reduces hardness in the body of the bit, which sounds counterintuitive but actually allows the shank to flex slightly under load rather than crack straight through. The tip retains the hardness needed to grip the fastener, while the body absorbs the punishment.
Where These 65mm Impact Bits Fit Into Your Workflow
The 65mm length makes these well suited to situations where a standard 25mm bit won’t reach comfortably, particularly when driving into recessed fixings, through jigs or templates, or anywhere you need a bit more distance between the chuck and the work. PH3 is the size you reach for with larger Phillips head screws, commonly used in structural timber work, decking, and heavier cladding applications. If you’re running a lot of No.10 or No.12 gauge Phillips screws, this is the bit you want loaded.
The black phosphate finish isn’t just cosmetic. It gives a degree of protection against surface corrosion, which matters if you’re working outside or storing bits in a damp van toolbox. They won’t last forever in wet conditions but they’ll fare considerably better than bare steel.
Double Ended Design
Both ends are identical PH3 tips, so there’s no guessing which way round to flip it. When one end rounds off or chips, you switch ends and keep going. For the price, having two usable tips per bit makes reasonable sense on a busy site. The 65mm ph3 double ended impact driver bit format is popular with fixers and joiners who go through bits regularly and want something that performs consistently without paying premium prices for a single-ended equivalent.
These come in a pack of two bits, giving you four usable tips in total. Keep a few packs in the bag and you’re unlikely to get caught short.
Pro Tip: When a PH3 bit starts camming out of the screw head before it looks visibly worn, check the tip under decent light: even slight rounding at the edges of the cross profile will cause that, and flipping to the fresh end will fix it immediately.
