Tight Fit Tools model 00100 Kit includes: a versatile close-quarter right angle drill attachment capable of drilling up to 1/4" diameter holes and compatible with all standard power drills, a 1/8 inch short TightFit threaded shank drill bit, and a TightFit three-way wrench (1/4" for screwdriver bits, 5/16" for drill bits and extensions, 7/16" for collets). Space, every inch of it, is at a premium in aircraft design as shape and weight is critical to function. Also, airplanes are riveted together which requires thousands of holes to be drilled in difficult locations without scratching or marring the work surface. So, engineers needed to design a versatile chuck-less drill adapter that could reach into very confined areas. The answer was found in putting threads on the shanks of drill bits. The benefits are significant. Threaded shank drill bits eliminate the need for a chucking mechanism. Freed of this restriction, it is possible to do a wide variety of jobs in places with extreme space limitations (less than 1" x 2"). Chuck slippage is all but eliminated while the precision mating angle between threaded shank drill bit and drive spindle insures concentricity. Drill bit change times are reduced, an exact working drill bit length is insured and the chance of marring or scratching the work surface is greatly reduced.This item can be a tool gift idea for any power drill owner. You will be able to make repairs and installations in near-impossible locations. Often, with its first use, the kit pays for itself in time and frustration saved. For example, the ability to drill-out a broken bolt in a tight spot can save hours. A power drill attachment that all power drill owners should have in their tool box. With care and maintenance, the kit should provide many years of trouble-free use. Suitability: for home, work, car, boat, RV and other repairs, installations and restorations. Note: drill bits comply with National Aerospace Standard 907B. All items ship USPS.
