Drilling down wall cavities with a long bit can be a challenge. Make your job easier with the FIB-GUD. The Folding Drill Bit Steering Guide permits you to hold, control and guide flexible shaft drill bits and extensions into wall cavities and other confined spaces. Place the tool over your flexible drill bit shaft and arc your bit into the proper angle of attack before drilling your hole. When not in use, the Folding Drill Bit Steering Guide can be folded to reduce its overall size for convenient storage and portability. Recommended when using any of their flexible drill bit extensions.
