How to Select Gun Drill Tool
Selecting the gun drill tool is a difficult process. This is because there are many different gun drill tools on the market. It is important to choose the right one for your job.
Choosing the right size is also important. This is because the tolerances of a gun drill can vary by size. For example, a 1mm 20x drill has a tolerance of +0.0005" to -0.001", while an 80x drill might have the same tolerance but on the negative side.
The correct size is determined by your application and the diameters of the parts you need to cut. You will also need to consider the length to diameter ratio of the hole being drilled.
You can get l:d ratios up to 400:1 on specialty gun drilling equipment. This is very important because it will allow you to drill holes in large diameters that can not be drilled with ordinary twist drills.
It is essential to start with a pilot hole that is 0.0005 - 0.001" larger than the gun drill you will be using. This will ensure that the gun drill does not get stuck in the hole.
Another factor is to make sure the guide hole is centered and straight. This is important because the gun drill will not be able to rotate properly in a sloppy or loose guide hole.
Once you have the pilot hole drilled and centered, you can begin to drill the part. If you are unsure about your gun drill, or you do not have the time to do it yourself, we can provide you with a professional gun drilling machine that will help you do the job correctly.
