Using an annular cutter still isn't considered to be thenorm, especially when you are talking in-homemachinery.
Using a metal hole saw has been the standard forsome time because most people didn't want to spendthe money on magnetic drills or larger pieces ofequipment.
However, now that an annular cutter can be used witha drill press, more people have been looking intoadding one as part of their metalworking arsenal.
Here are a few benefits that you could gain from doingthis as well. Keep in mind that most of these benefitsstem from comparing an annular cutter to a standardtwist drill.
One of the biggest benefits that the average personwill notice is that using an annular cutter can saveboth time and energy.
For example, if you are currently using a twist drill ormetal hole saw, there is a good chance thatcompleting your project will include a number ofdrilling steps.
However, with the cutter you will be able to do this allin one step because it is designed to eliminate theneed for pre-drilling.
Additionally, you save time because you can work at afaster cutting speed.
While you will still need to use some form of coolant,all of the actual cutting will be done at a much fasterfeed rate. This is because they have more teeth andless tool wear.
Another benefit is that an annular cutter can beutilized with much less powerful drilling equipment.Since it does not try to drill through the entire piece ofmetal, it takes less power to complete the project.
In this regard, it is very similar to a standard metal holesaw. The only difference is that this type of bit is muchmore efficient.
This not only saves energy, but also makes the entirejob much easier to complete.
Additionally, you can drill all of your holes without pre-drilling or step drilling.
Because of its unique design, you will be able to createholes that were previously very difficult or nearimpossible to achieve due to awkward angles.
Plus, an annular cutter is much more precise andaccurate than your standard twist drills.
Finally, it is much easier to add coolant through thetool center pin, which makes deep hole drillingpossible with a single, non-stop step.
As you can see, there is a wide range of benefits tousing an annular cutter, especially if you currently usea twist drill. It even has a number of benefits over astandard metal hole saw.
While there are many benefits to using this tool, thesix most prominent benefits include: saving time,saving energy, using faster feed rates, using lesspowerful and lighter equipment, drilling awkwardholes accurately, and facilitating coolant feeding thanksto the tool center pin.
With such an array of advantages, it is no surprise thatmore people are opting for an annular cutter over thetraditional twist drill.
With so many different advantages to be had, it is nosurprise that more people are opting for an annularcutter over the traditional twist drill.
It is surprising how many people still use a regular biton a twist drill to create holes in denser materials suchas metal. This can be especially difficult if you aretrying to create large holes.
It is much easier to use a simple attachment called anannular cutter. It is designed specifically to help youout in this type of situation.
Depending on how you plan on creating your hole, ametal hole saw might be a good option as well. Hereis a closer look at why you should ditch your twist drilland bit and upgrade to much more advantageoustools.
The main reason many people are moving away fromtwist drills is that they can quickly turn a very efficientoperation into a very slow and tedious one.
The design of your standard twist drill really hasn'tchanged much over the last few centuries.
Even with enhancements like carbide tips and coredrills, the overall product is still not as effective as itshould be. This is because twist drills do two thingssimultaneously: cut and chisel.
Due to its design, its effectiveness is limited by theavailable horsepower behind it. Instead of battlingagainst the drill, using an annular cutter can provideyou with the same output of work with much lesspower.
Additionally, because of the extra pressure and thrustrequired with a twist drill, in most cases only twocutting edges have to do all of the work. This not onlycauses premature wear and tear, but also means thatthere is a slower feed and metal removal rate.
Essentially, the more teeth available for cutting, themore efficient your drill will be. That is why the metalhole saw became popular in the first place.
However, if you don't want to purchase a new piece ofequipment, there is a number of different ways tointegrate an annular cutter with the drill or press thatyou already have.
An annular cutter is different than your regular drill bitbecause it is hollow and offers multiple cutting edgesas opposed to only two. Plus, the lowered inner andouter edges means that each tooth has a lower totalwork load.
Because the tool is hollow, the surface that you arecutting and converting into chips is much smaller thana traditional twist drill. This means that higher feedrates and less power is required.
Additionally, because you need less thrust, this type ofcutter also requires less energy to operate.
In short, using an annular cutter instead of yourtraditional twist drill bit is more efficient in everyaspect. If you are drilling a hole that is particularlylarge, then a metal hole saw might be your bestoption.
Either way, a traditional twist drill will always be yourmost inefficient option. As there are fewer cuttingpoints it requires more energy, horsepower, and thrustto achieve the same results over a longer period oftime.
If cutting holes is something that you need to do on aregular basis, then it is probably time to look into moreefficient options.
