"I had never seen an adjustable drill bit like this before, and I needed a couple of different size bits for a decking project. I thought I'd give this a go as it was cheaper than buying a full set. First impressions are good, with a strong feel to it. It's adjustment is simple and it has tackled the work I have thrown at it so far. Saves room in my toolbox too!"
"Bought this bit for a specific job and required something that would allow me to drill large holes approximately 100mm deep but was unsure the exact diameter required. This bit fitted the bill and have now drilled one hole 55 mm diameter and the bit did the job no problem. Only another 11 holes to drill but indications are this bit is up for the job. Most pleased with my purchase and at a reasonable price too."
