Knowing the difference between drilling, boring, and reaming which is quite confusing to most people. Today I will be clarifying their differences to you.

Sure, drilling boring and reaming are three different processes performed by manufacturing companies. They involve creating and modifying holes on a workpiece. Well, most people are familiar with drilling while boring and reaming might sound strange to some people. Now you’re about to get the breakdown between the processes.



Drilling is a cutting process in which a drill bit is used to cut a circular-shaped hole in a material. The cutting material used is a rotary metallic material called a “drill bit” which contains a sharp tip that aids the cutting. This scraps out the material when the drilling machine is pressed against the workpiece. This drill bit digs away material as the cutting tools enter the workpiece.

Drilling is carryout on both wood and metal, but most people assume it is performed on soft materials like wood. well, this is to assure drilling can be done on harder materials as long as the drill bit is hard enough to enter the workpiece.

This operation is quite different from a drilling operation as involves the use of a single-point cutting tool or boring head to enlarge an existing hole in a material. it is done mostly in drilling operations when the diameter is needed to be increased, so a boring head of a larger size will be fixed on the drilling machine.

Boring is likely to be performed on the lathe, milling machine, or a horizontal boring mill. The working of these machines is totally different, but they are designed to enlarge an existing hole on a workpiece.

So, the difference between drilling and boring is that drilling is performed to create an initial hole in a workpiece. Whilst, boring is done to increase the diameter of an existing hole in a workpiece.

Reaming is another cutting process that uses a rotary cutting tool to create smooth interior walls in an existing hole in a workpiece. Comparing reaming with drilling, the reamer removes significantly less material than the drill bit. But the primary purpose of reaming is to create smooth walls in an existing hole. Most manufacturing companies perform this operation mostly on a milling machine or drill press

Reaming and boring differences

Finally, the major difference between drilling, boring, and reaming is quite simple. In drilling a new hole is created, boring increase the diameter of an existing hole and reaming cuts a fine interior wall on an existing hole.
