Frequently Asked Questions (FAQs)

1. What type of drill bit is needed 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.

2. Will a regular drill bit work on aluminum?

No Fancy Drill Bits for Metal Required Almost any general-purpose twist bit will do a decent job of drilling holes in metal. In fact, most drill bits for metal are manufactured to drill through a variety of materials, including wood and plastic.

3. Are titanium drill bits good for aluminum?

Titanium bits are suitable for drilling iron, steel, aluminum, magnesium, and wood. Titanium bits are great for general purpose drilling in a production environment because they drill quickly.
