Then, is it hard to drill through aluminum?
“Aluminum is a generally soft, nonferrous, ductile material with low density and naturally high resistance to corrosion. Aluminum is difficult to drill because its ductility and softness causes the material to make constant prolonged contact with the rake face, or cutting edges, of a drill.”
One may also ask, can you drill through cast aluminum? It should do fine in aluminium, so long the as-cast holes are straight, and you are not significantly off-existing-axis when opening them up. Downside is they are not as easy to find 'just anywhere'.
Accordingly, what type of drill bit is needed for aluminum?
High-speed steel (HSS) drill bits can drill wood, fiberglass, polyvinyl chloride (PVC) and soft metals such as aluminum. Cobalt drill bits are extremely hard and dissipate heat quickly. They're mostly used for boring in aluminum and tough metals such as stainless steel.
What speed should aluminum be drilled at?
How to choose the right drill speed
|Material||Speed Range (SFM)||RPM recommendations based on First Guess Speeds for various drill bit diameters|
