[QUOTE="Armeg UK, post: 456836, member: 18568"] Rob, you're right about most readily available battery drills having incorrect speeds to run metal drills properly. Alternatives involve investment unfortunately which some people will see far outweighs replacing drill bits. There are some battery drills out there with speed ranges that are more geared towards engineering tasks. Also I know of one power tool company that have tools that have Bluetooth connectivity meaning that the rotational speed can be set more accurately using an app :innocent Regarding designing hole saws that are capable of running at faster speeds, it might be worth looking at these [URL="http://www.armeg.com/LDX-Metal-Carbide-Tipped-Holesaws"]http://www.armeg.com/LDX-Metal-Carbide-Tipped-Holesaws[/URL] These are carbide tipped holesaws for massively longer life over conventional holesaws. The recommended speed for a 20mm in mild steel is about 700 RPM so you're not going to kill it on first speed range of a battery drill. In independent tests in 2mm thick stainless steel they were producing 350 holes so life is good too. [/QUOTE]
