What drill speeds for steel and aluminum?

11/04/2012· The cutting speed for mild steel is ~80-100 FMP. To figure how many RPM's to turn your drill, simply ply the cutting speed x 4 then divide by the diameter of the drill. So for a 1/4" hole in mild steel, 80 x 4 /.250 = 1280 RPM. Small drills need lots of RPM's or they end up getting broken or damaged from too much feed pressure.

High-speed steel - Wikipedia

High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material.. It is often used in power-saw blades and drill bits.It is superior to the older high-carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness).This property allows HSS to cut faster than high carbon steel, hence the name ...

Drill Speeds - Curious Inventor

Quick Summary: Some approximate starting advice is to set the spindle speed between 700-1000 rpms for steel, above 2000 for aluminum, and slow down from there if you get discolored chips or heavy drill bit wear. In most cases the drill press will not be able to supply enough power or speed to follow the below recommendations.

A typical drill press often has an RPM limitation of between 2000-3600 RPM. If the chart above specifies a higher RPM than your machine is capable of, it should not cause a problem to run at a lower RPM. For instance, many people drill 1/16″ holes at less than 10,000 RPM with no problems.

Know How: Drilling Stainless Steel - Sail Magazine

02/08/2017· Thanks to the advice of an exceptional metal worker, I learned the right way to drill stainless with standard High Speed Steel (HSS) drill bits. Stainless is actually a relatively soft metal, at least in its initial state. What stainless tends to do is "work harden" fairly quickly when heated, and drilling at high speed creates a lot of heat. When stainless steel work hardens, it becomes ...
