Service your RC fleet and delicate boat hardware with this professional 5-piece tool set. Designed for hobbyists who demand precision, the set replaces a toolbox full of loose drivers with five specialized handles made from lightweight aluminum and durable alloy steel. The ergonomic knurled grips provide a secure, non-slip feel for intricate maintenance on scale crawlers, RC sailboats, drones, and small outboard motor assemblies. Each tip is treated with a premium titanium coating, boosting surface hardness to resist wear and corrosion so your tools stay sharp even with frequent use. A universal 6.35 mm (1/4") quick-change chuck on every handle makes bit swapping effortless and allows compatibility with your power screwdriver. Whether you are adjusting a rudder linkage, tightening a motor mount, or rebuilding a nitro engine, the included 15-bit profiles mean you will always have the right tool within reach.

A: Yes. The set is designed for precision models, including RC boats. The small hex sizes (especially Handle A) are perfect for tiny set screws on model marine engines, while the nut driver (Handle C) fits linkage and prop hardware.
A: The steel alloy tips have magnetic properties which helps hold small steel fasteners. For stainless steel or non-magnetic screws, a small dab of grease on the tip can help place the screw.
A: The titanium coating increases surface hardness and significantly improves corrosion resistance compared to standard black steel. It helps protect the tip from rust if exposed to moisture. We still recommend a quick wipe with an oily cloth if used near saltwater.
A: Yes. The handle features a 6.35 mm (1/4 inch) hex quick-change socket. You can directly insert your electric screwdriver bits into these handles, or pop out the included tips to use in a power driver.
A: These are single-size fixed drivers. Handle D comes with a dedicated 4.0 mm tip, and Handle E comes with a 5.0 mm tip. They are ideal if you use these sizes frequently and don't want to swap tips on Handle A.
