Makita B-63725 Impact Black Screw Bit PH2 (magnetic, 50 mm) – 2 pack

The essentials

Makita’s B-63725 Impact Black Screw Bit PH2 is a specialist screwdriver bit designed for PH2 heads, with a magnetic hold and a 50 mm working length. It’s the sort of small, easy-to-miss item that becomes genuinely useful when you’re doing lots of screwdriving and want the bit to sit properly without constant fiddling.

The “impact” part of the name is the standout angle here. Over time, ordinary bits can lose a bit of edge or start to round off when they’re pushed hard. This one is positioned as an impact-use bit, so on paper it suits jobs where you’re driving screws quickly or applying more force than a delicate assembly.

If you’re the kind of buyer who keeps a bit organiser and just wants replacements that match your existing tools and PH2 screws, this 2-pack makes practical sense.

What you’ll notice day to day

In use, the magnetic element is the day-to-day feature. It helps keep the screw aligned to the tip, which is especially handy when you’re working overhead, reaching into awkward corners, or trying to start screws without dropping them. The 50 mm length also helps with slightly deeper setups where a short bit feels like it barely reaches.

One small limitation to bear in mind: this is PH2-specific. If your projects use a different Pozidriv size (or a Phillips that’s not PH2), this bit won’t be a direct substitute. It’s a tidy replacement, not an all-sizes answer.

Key features

The core details are straightforward and geared towards a clean fit: - Screw head type: PH2 (Pozidriv/Phillips style seating depends on your screw, but the bit is PH2) - Magnetic: built to help hold screws on the tip - Working length: 50 mm - Shank type: 1/4 inch hexagonal - Pack size: 2 bits

If you’re regularly maintaining or building with PH2 screws, having a spare (or two) is where this kind of product quietly pays off.

Who it suits (and who should skip it)

It makes sense if you already know you use PH2 screws and you want a magnetic impact-style bit that’s long enough for everyday jobs. You’ll likely appreciate it for common home and workshop tasks where you’re driving multiple screws—think furniture assembly, general fixing, or any repeat batch where starting screws accurately matters.

It might not be the best match if you’re buying “just in case” for mixed projects. Since this is PH2 only, you may end up with a drawer full of bits that don’t get used. Likewise, if your workflow doesn’t benefit from magnet-assisted starting, you might prefer a simpler bit type for the jobs you do most.

Getting the most from it

A bit like this is at its best when it matches the screw head size and you keep the tip seated properly. If you notice the tip slipping or the screw head looks chewed up, stop rather than pushing through—incorrect seating is usually the culprit, not the bit alone.

Also, because the working length is 50 mm, it can reach where shorter bits struggle, but it can also feel a little more “long-reach” in tight spaces. If you often work in very cramped areas, you may find a shorter bit more controllable.

Final verdict

Is it worth it?

Worth buying if you want a PH2 impact-style magnetic bit in a practical 2-pack, especially for repeat DIY or workshop screwdriving where alignment and fast starts save time. It’s the kind of replacement that slots neatly into an existing toolkit thanks to its 1/4 inch hexagonal shank and 50 mm length.

You may want to skip it if your projects use different screw head sizes, if you only drive a handful of screws occasionally, or if magnet-assisted starting isn’t important for how you work. In those cases, it can be more money spent on the wrong “drawer item” than a useful upgrade.
