Based on our own experience, this auger extension will make your drilling job a breeze .The quality of the build is impressive and it perfectly complements heavy duty drills. The extension comes in different lengths giving it a versatile appeal. It's a valuable addition to any industrial and scientific toolkit. However, the pricing might be off putting for some..
The product supplied will only fit bits with a maximum shank of 5/16" - they will not fit this extension at all. Acceptable for twist drills, but they are not the center either.
