10Pcs 50mm Philips Screwdriver Bits Set (PH1x50)

A 25mm bit sitting in a holder or a chuck leaves very little sticking out, so the chuck or the holder fouls on anything surrounding the screw — a recessed fixing, a screw inside a moulding, a fastener in a corner or a channel. A 50mm bit puts the tip out where it can reach, with the chuck clear of the work. Anybody assembling cabinets, fitting hardware into recesses, or driving screws in confined framing finds the longer bit does jobs the short one cannot.

PH1 is the cross-head size below the very common PH2, fitting smaller machine screws, appliance and equipment fixings, electrical accessories, hinges and light hardware.

The specification worth reading is S2 industrial steel at HRC 58-62. S2 is a shock-resisting tool steel, chosen because a bit in a power driver is hammered and cammed thousands of times — it can be hardened hard while still absorbing impact rather than shattering. HRC 58-62 is much harder than a hand screwdriver blade, which sits nearer 50, and that is deliberate: a power driver spins fast and cams out repeatedly, and without that hardness the flutes round off in a day.

That matters because a worn bit does not merely stop working, it starts damaging screws — a rounded tip cams out of every recess and rounds the head as it goes, and the wear is gradual enough that people keep using it.

Satin finished, ten per plastic case, which keeps them findable and dry.

The buyers are carpenters and joiners, shopfitters and installers, furniture and cabinet fitters, electricians, appliance technicians, maintenance staff, and hardware dealers.

Two habits. Press hard into the screw while driving — the Phillips recess is designed to cam out and pressure is the defence. And a longer bit flexes slightly more than a short one, so keep the driver square to the screw. Message us on WhatsApp for a price.
