Drilling a perfect hole is easier said than done, and the top drill rig companies in the country agree to this. If you are not a professional in this area or don’t have any prior experience on this, engaging oneself in such an arduous, physically taxing undertaking can easily escalate, in no time, as a major problem.
You grab yourself a suitable drill bit, and onto your drill press you will attach it, turn it on. Then, all along you are doing things great and good, and then in a snap, a slight thing goes wrong and everything about the hole you are drilling goes awry and far from being perfect.
Drill rig companies are used to that and have found out some good and practical workaround in some of most complained about issues in the drill rig business.
We have below a rundown of some of the most common issues anyone can encounter with their drill bit and ways on how you can avoid them.
Broken Drill Bit
Everyone can experience this kind of problem when working on a drilling project. It is important to understand, though, that you will never be at fault here. There are a handful of underlying reasons why this issue can happen:
You can keep this problem from taking place if you will check your speed and at the same time also make sure you are using the right kind of coolant. The use of the wrong coolant will pave the way for an excessive run out while the drill is breaching the metal.
Clogged Flutes with Chips
If you seriously want to shun this issue from happening to your drill bits, you can just opt to use ones that come with wider flutes, instead. Alternatively, you can also take out the drill bits at certain intervals. This will significantly help a lot in clearing the chips away.
If the chips are not broken, you may consider the use of a chip breaker design or heavier feeds. Moreover, you can also try using polished flutes here.
We have but one easy workaround for this kind of concern, and that is to decelerate the feed.
Too Dull Twist Drill
Before you commence any drilling work, consider checking out the drill bit first. There are times that you just need to give it some resharpening work. Or that it might be calling for some replacement part already.
Drill bit slipping
Have a closer look at the chuck and see to it that it is holding tight your drill bit. Otherwise, you may just resort to using a drill bit with a shaft that comes with 3 flats. This allows you to have a better, more powerful grip on it, preventing it from slipping away.
Damaged Point Angle
You will have this issue if you happen to hit the drill into the socket by virtue of the metal hammer. You can prevent this issue from happening by taking advantage of a soft lead instead, such as a plastic hammer.
Be reminded also that you need to be extra careful not to mishandle the jobber drill.
Too Large Hole
You may be using just the right size of the drill bit, however, if the issue is you have a hole that is either too large or too small, you may try the following suggestions:
- Your drill point may be off-center. In such a case, replace or repoint it to enhance accuracy levels.
- Consider making tweaks to the machine spindle. It may not run the way that it did before or it is not rigid enough.
- Finally, tighten your work.
Hole with rough edges
Drill rig companies say that nothing can be more disappointing when you have a hole with rough edges. You can prevent this kind of problem though by replacing the jobber drill.
The odds are high that the drill bit you are using here is dull already and that the ground point is incorrect. Also, make it a point that you will reduce the feed and that you are having a proper coolant for this purpose.
