"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."
"All the sizes you need for wood in one drill bit. I have used this item in the tail stock of my wood turning lathe with great effect. Will bore 22mm to 76mm with little effort. It is sturdily constructed and easy to sharpen with a diamond sharpening tool. The holes it makes are smooth and accurate."
"Just bought this... Needed it to work as it was an important job and is awful. Haven't even got it in to the drill and the smaller attachment doesn't fit so I've had to tighten it as much as possible. Now the screw that holds the attachments in has rounded off! Do not buy!"
