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.19 ביוני 2020
Can you drill through aluminum with a drill?
“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.”1 בפבר׳ 2016
Can you use a paddle bit on aluminum?
no, don't use a spade bit, aluminum has a way of grabbing a drill bit and that can lead to an accident. If you have a drill pess that stands on the floor instead of one of the very small ones, you can purchase a 3/4-inch twist drill bit.17 באוק׳ 2010
Do you need oil to drill aluminum?
“Unlike our other bits, it doesn't require our special lubricant; it can operate with standard machine coolant,” Ray said. “It also countersinks a chamfer into the material, which makes it the only one of our bits that generates a chip.”1 בפבר׳ 2016
How do you drill through thick aluminum?
With thick aluminum, I usually start with an 1/8" pilot hole, take that to 1/4", then 3/8", then 1/2". With an inch to go through, you may also need to use a 5/16" bit to ensure a nice round hole at the end. When you ask a drill to cut too much metal at a time it will bend, wiggle and give you a poorly shaped hole.27 בינו׳ 2012
Can you use a regular drill bit for aluminum?
1. Choose a suitable drill bit. 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.19 ביוני 2020
