Minimize burrs drilling Aluminum
Jon Elson fired this volley in news:r-
:
If the work is clamped securely, you can use an end mill to drill
through. It leaves a lot less burr than a regular drill bit.
To ensure proper chip clearing (even with center-cutting mills), you should
first drill a pilot hole about 30% of the finished diameter.
