There is some confusion about the role that reamers play when it comes to creating a hole. Those with very little idea about DIY and power tools mistake it for a normal drill bit and believe it can produce the same results.

A reamer is a drill bit that is used to shape or enlarge holes. Now, there are many different kinds of reamers. There are the adjustable hand reamers, the straight reamer, the machine reamer, the rose reamer, the shell reamer, the tapered reamer, the Morris taper reamer and the combination reamer.
