[QUOTE="Rob., post: 456826, member: 27131"] Aside from a lot of people being misinformed on speeds they should be drilling there are a couple of factors to bare in mind: [LIST][*]Most battery or even corded drill wont have a setting to run slow enough (Without feathering the trigger). I'm no expert in metallurgy but could an alloy be designed to run at normal battery drill speeds? I realise this is probably impossible due to hardening effects of material being drilled, stainless is a great example. (I also guess if it was designed, sales would drop as the bits would last a whole lot longer) [*]Another factor is if the cost of the drill bit is less expensive then the extra time taken to drill x amount of holes at a slower speed. I know at my hourly rate the client would rather me charge for a couple of ruined bits at £20 than 30min of my time spent properly drilling. [/LIST] [/QUOTE]
