Frequently Asked Questions (FAQs)

1. Can you countersink aluminium?

Yes,it will be OK but the Ruko ones give a smoother finish but the smallest they will do is a 3.0mm hole as the tip is 2.5mm . Use a slow speed when countersinking, and a bit of parafin is a good cutting fluid for ali.

2. What kind of bit do you use for aluminum?

Aluminum is a soft metal and therefore a standard HSS drill bit will be able to drill into it. However because of the low melting point of aluminium a better choice would be to use a cobalt drill bit. The cobalt drill bit will dissipate heat quicker and ultimately assist in reducing heat build up.
