Adjustable Bit-Guide with Suction Cup

The bit guide is used to position core bits in place when you drill to eliminate expensive mistakes. The 4" diameter suction cup is used to secure the guide. The guide can be adjusted from 1" to 2"  and suitable for core bits from 1" to 2" in diameters. The body of the guide is metal to ensure durability.

When deciding if you want this guide, please be aware that the diameter of the suction cup is 4". The surface you are drilling must have enough room for the suction cup and guide.
