J&R Hobby Hardware: Ball-Hex Bit Set

Model Airplane News, Feb 2005 by Reid, John

Easy access, more torque

I'm always on the lookout for versatile, compact, durable tools that I can assemble in the perfect flying-field toolbox. J&R Hobby Hardware now manufactures a new product that takes care of my hex driver needs. Its new 2 ½-inch-long ball-hex bits are perfect for anyone who uses hex screws in a variety of sizes. These high-quality ball-hex bits can be used with manual and cordless hex drivers and are available in metric and standard sizes. I can fit a complete set of ball-hex bits in a small compartment in my parts tray.

The advantage of using a ball-hex bit instead of a hex wrench is that you can attach a ratchet screwdriver or handle, a battery-powered electric screwdriver, or a cordless electric drill to rapidly install or remove a hex screw or bolt. The ball head allows the bit to drive the bolt in with high-torque power, even when the bit is inserted into the hex screw or bolt at an angle. The 2 ½-inch-long hex bits allow you to work in tight quarters without damaging the area with the drill's chuck. If you need a longer reach, J&R Hobby Hardware offers 6- and 12-inch magnetic extensions that cost $2.50 and $6.50, respectively. They will allow you to reach way into the fuselage or wing cavity to reach any hex bolt or screw. If a screw falls into the cavity, use the extension rod to retrieve it!

The standard set includes nine popular bit: sizes (½, 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32 and 3/16-inch) and costs $20. The metric set comes with seven bits that range from 1.5 to 5mm; it costs $15. Pick up a set for yourself and make assembly and disassembly at the field a breeze.
