The Porter Cable PCXB115MS is one of those older cordless combo kits that still turn up in garages, job site trailers, and online marketplaces. It pairs an 18-volt drill/driver with an impact driver, along with batteries, a charger, and a carrying case. For anyone considering a used unit or trying to get one back into service, understanding what this kit does well—and where it falls short by today’s standards—is essential.
This guide covers the tools included in the PCXB115MS, how they perform in real-world drilling and fastening, and what to check before buying or relying on one for regular projects. It also explains the battery platform, maintenance needs, and who should still consider this Porter Cable kit in a market full of modern brushless tools.
What Comes in the Porter Cable PCXB115MS Kit?
The PCXB115MS is generally sold as a two-tool combo kit. The exact contents can vary by listing, but the core package is consistent: a cordless drill/driver, an impact driver, two 18-volt batteries, a charger, and a bag. This makes it a starter kit for drilling pilot holes, driving screws, and handling light to medium fastening tasks.
Because it belongs to Porter Cable’s older 18-volt NiCd era, the kit feels different from today’s compact lithium-ion systems. The tools are generally heavier, the batteries require more careful charging habits, and replacement packs are not as easy to find at local stores. Still, the basic combination of drill and impact driver remains a practical setup for many DIY tasks.
The Drill/Driver in the PCXB115MS
The drill/driver in this kit typically features a 1/2-inch keyless chuck, a two-speed gearbox, and an adjustable clutch. That makes it suitable for boring holes in wood, driving long screws with control, and using hole saws or paddle bits in light applications. The two-speed range gives you lower speed for torque-heavy tasks and higher speed for smaller bits.
In use, the drill/driver is best treated as a general-purpose tool rather than a heavy-duty workhorse. It can handle furniture assembly, deck repairs, cabinet installation, and basic remodeling tasks. However, in hardwoods, thick metal, or repeated large-hole drilling, it will not match a modern brushless hammer drill or a high-voltage cordless drill.
The Impact Driver in the PCXB115MS
The impact driver uses a 1/4-inch hex chuck and delivers rotational force plus rapid concussive blows. That combination makes it excellent for driving screws and lag bolts without stripping heads or over-torquing as easily as a drill. In the PCXB115MS kit, the impact driver is often the more impressive tool for its size and age.
It shines on framing, decking, fencing, and automotive or assembly work where you need rapid fastener installation. The impact action also reduces wrist strain compared with using a drill for long screws. Just keep in mind that it is not a precision torque tool; for delicate materials, use the drill/driver’s clutch or a manual driver.
Performance and Real-World Use of the Porter Cable PCXB115MS
The PCXB115MS was designed for homeowners and tradespeople who needed dependable cordless power before lithium-ion became the default. Its performance is best judged against that era, not against today’s compact brushless kits. For moderate tasks, it still has enough speed and torque to get work done, especially if the batteries are healthy.
Runtime and power depend heavily on battery condition. Old NiCd packs that have been sitting unused for years may charge but fade quickly under load. A freshly rebuilt or well-maintained battery can make the tools feel surprisingly capable. If you are comparing this kit to a new 20V lithium combo, expect the modern kit to be lighter, stronger, and longer-running.
Drilling, Driving, and Fastening Tasks
For drilling, the drill/driver handles twist bits in wood and metal, spade bits in softwood, and smaller hole saws. The clutch helps prevent screw heads from sinking too deep in drywall, plywood, or soft pine. The impact driver takes over when you need to drive dozens of screws quickly or work with longer fasteners that would stall a basic drill.
Examples include building a raised garden bed, repairing a fence, installing shelving, assembling a shed, or doing light deck maintenance. The impact driver can drive structural screws and lag bolts with the right pilot holes, while the drill handles pilot holes and mixed drilling. For cabinet hardware or electronics, use lower clutch settings or switch to a hand tool to avoid damage.
Battery Platform and Runtime Expectations
The PCXB115MS belongs to Porter Cable’s 18-volt NiCd system. NiCd batteries are known for their memory effect, self-discharge, and need for periodic full discharge and recharge. They also contain cadmium, so disposal and recycling should be handled properly. The charger in the kit is typically a one-hour or similar charger, not a fast modern smart charger.
Runtime will vary by battery amp-hour rating and age. Expect enough power for light to medium tasks, but not all-day production work. If you plan to use the kit regularly, having at least two healthy batteries is important. Many owners also look for aftermarket NiCd replacements or adapter solutions, though those can be hit-or-miss in quality and fit.
Maintenance, Buying Advice, and Ownership Tips for the PCXB115MS
Because the PCXB115MS is an older platform, maintenance and inspection matter more than they would with a new tool. A used kit can be a bargain if the batteries and charger work, but it can also become a paperweight if replacement packs are unavailable or the tools have worn chucks, triggers, or motors.
When shopping used, ask about battery age, charger function, and whether the tools run smoothly through their speed ranges. Test the drill’s clutch, the impact driver’s bit retention, and the forward/reverse switch. If possible, bring a known-good battery or ask the seller to demonstrate the tools under load.
Battery Care and Replacement Options
To get the most from NiCd packs, avoid leaving them on the charger indefinitely, store them in a cool dry place, and run them down occasionally before a full recharge. If a pack becomes weak, it may need to be cycled several times or rebuilt. Do not puncture or discard NiCd batteries in regular trash.
Replacement options include original Porter Cable 18V NiCd batteries, aftermarket packs, and rebuilt battery services. Compatibility can be confusing because newer Porter Cable 20V MAX lithium batteries are not the same platform. Some users explore adapters, but performance and safety vary. Always confirm voltage, terminal style, and tool compatibility before buying.
Who Should Consider the Porter Cable PCXB115MS Today
The PCXB115MS makes the most sense for budget-conscious DIYers, occasional users, or someone who already owns compatible Porter Cable 18V NiCd batteries and a charger. It can handle home repairs, furniture assembly, and light remodeling without a large investment, especially on the used market.
It is not the best choice for professional contractors who need all-day runtime, compact size, and modern lithium batteries. Those users should look at current 18V or 20V brushless combo kits. For a homeowner with modest projects and realistic expectations, though, the Porter Cable PCXB115MS can still earn its place in the garage.
If you find a clean PCXB115MS with healthy batteries and a charger, it can be a practical entry point into cordless drilling and fastening. Check the battery condition first, compare the price against a modern entry-level combo kit, and decide whether the lower upfront cost is worth the trade-offs. A little patience at the point of sale will tell you whether this older Porter Cable set is a smart buy or a project waiting to happen.
