An Annular Cutter Can Create Better Holes Than A Drill

When you ask someone how to create a hole in a piece of metal or wood, the automatic response will undoubtedly be to use a drill. All things considered, this method has been taught in metalwork and engineering classes up and down the nation for decades. However Annular Cutter, sometimes a typical twist drill isn’t the answer. Depending on the material, it might cause the surface area across the hole to dimple or burr that could ruin the whole project. An annular cutter is a tool that is often used instead of a regular drill because it has the ability to cut an ideal hole without damaging the remaining material. Reamers may also be used to create minor adjustments/enlargements to the hole.

While twist drills remain a typical method of drilling holes, they have major flaws which were picked up on by engineering companies in search of perfection. Its point is clearly two cutting angles which intersect inducing the phenomenon referred to as the’dead zone ‘. The situation with this specific’dead zone’is so it forces the speed of the edges to grind to a halt. This drop in speed causes great inefficiency in the cutting process and makes it harder for the edges to push through the surface of the material. If pipe or tubing will be drilled, the possible lack of speed results in increased drill pressure that causes the material to dimple.

The reason why an annular cutter is more successful in this instance is because it’s hollow and therefore does not suffer from the’dead zone’problem. When this is with the fact that the cutting edges are out at the edge it means that the speed of the drilling remains the same through the entire procedure. When by using this bit of machinery, always ensure that the speed where it cuts is kept at a higher level otherwise the edge will dull. In many ways, this is actually the opposite of the metal hole saw which goes blunt when its speed setting is consistently too high.

Reamers are successful in regards to making minor adjustments to a hole. As soon as you try to tackle too big a job, the reamer can be ineffective and be in peril of being damaged. In case a reamer is used, it should not be put backwards as here is the quickest way to blunt the cutting edges. Anyone who has ever taken a design class in school may have observed this machine stuck in a lathe or drill press. Before it’s turned on, the job piece must be held rigidly by a chuck or vise for safety reasons.

As you can see, twist drills aren’t the only real device that will create holes and alter them. An annular cutter will give you a more accurate hole and will not be marred by unsightly dimples. Reamers will serve you well if you choose that a hole is not exactly the right size and requires a minor adjustment. Be wary when working with both sets of equipment must be slight mistake is all it takes to create a mess of previously good work.
