The Uses of Bench Drilling Machines

A bench drilling machine is more commonly found in a machine shop than in someone's garage or casual work shop. These machines are large and stationary, often the height of the user if not taller. They require a power source and can sport a variety of different bits to drill a number of different holes. With the proper bits, a bench drilling machine serves a wide variety of uses.

Drilling

The basic function of a bench drilling machine is to drill holes in wood, metal and a variety of other materials provided the machine has enough power and the proper drill bits. For instance, a wood drilling bit is made of different materials and is shaped differently from a metal or concrete drilling bit. Although drilling is the most common task for these machines, it is by no means the only task they can perform.

Boring

With the proper set-up, a bench drilling machine can be altered so that it becomes a boring machine. A boring bit is much larger than a drill bit, although it serves essentially the same function. Rather than drilling a small hole that will be filled by a screw or nail (a pilot hole), a boring bit creates a large hole that may not be meant to be filled. Much like a tunnel boring machine, a boring bit merely carves out part of the material for a construction purpose. To turn a bench drilling machine into a boring machine, you simply have to switch the bit.

Buffing

For mechanical buffing, a bit can be put on the end of a bench drilling machine to turn it into a buffing machine. The downward force you can get with a bench drilling machine saves a lot of heavy muscle work that would be spent trying to buff a particularly resistant piece of metal by hand. Portable buffer bits can be put into a hand drill, but those will still require a lot more force from the worker than a similar bit used in a bench drilling machine.
