The RC10 Tool Set That Fits How You Work – Koswork KOS13207-T1RC10 & KOS13204-1/4RC10
The RC10 uses standard inch sizes throughout, and having the right set of hex wrenches and nut drivers on hand makes the difference between a smooth build session and constantly hunting for the right tool. Koswork makes two versions of the same 7-piece set — identical tips, same sizes, same compatibility with the RC10 — but with different handles designed around different preferences for how you work at the bench and in the pit.
Both sets include the same seven tips: .050″, 1/16″, 5/64″ (2mm), and 3/32″ hex wrenches, plus 3/16″, 1/4″, and 11/32″ nut drivers. All tips are hardened steel, 75mm long, with a 1/4″ hex shank that’s compatible with electric power tools. Made in Taiwan.
T1 Aluminum Handle with Internal Storage: KOS13207-T1RC10
The KOS13207-T1RC10 uses Koswork’s T1 aluminum handle — precision-machined, 26mm diameter, with an internal storage compartment that holds the tips inside the handle itself. The quick-release mechanism and built-in magnet hold whichever tip is installed securely in place and make switching fast. The 11/32″ nut driver comes pre-installed at the front end as supplied. The ergonomic design gives you a solid, comfortable grip for extended work, and the aluminum construction keeps the weight reasonable without sacrificing feel. Handle length 116mm, overall length 180mm with the 11/32″ driver installed. If you want everything in one self-contained unit that doesn’t require a separate holder, this is the set.



Light Tri Handle with Tip Holder: KOS13204-1/4RC10
The KOS13204-1/4RC10 takes a different approach. The lightweight composite tri handle is ergonomic and easy to grip, with a magnet installed to hold the tip in place. The tips are stored in a separate convenient tip holder that comes included with the set — a layout that some builders prefer because it keeps all tips visible and accessible at once rather than stored inside the handle. The tri handle profile gives good control for precise work, and the lighter construction makes it easy to use for extended periods. Handle length 105mm, overall length 170mm. If you’re already comfortable with a Handy-style handle or prefer your tips laid out in front of you, this is the one.


Both sets are available through your local Koswork dealer or authorized distributor worldwide.
