Why is speed described as 0-1200 RPM and review says it starts at either 250 or 600 RPM? I need something with true variable speed.

It definitely does not have a gradual start, as some have indicated in the reviews. The lightest first contact in the trigger yields around 300 RPM's unloaded on my drill (I checked with my touch-tach). With the level of power this drill offers, even at this lowest trigger position the drill won't stall without a large amount of load. If you need delicate low-speed operation such as fastener driving, look for a smaller drill (perhaps a 3/8" VSR?). If you need a drill that will work continuously poking 3/8" to 13/16" holes in up to 3/8" thick steel as I did, this is your drill.

Mine that I just got today definitely has a gradual start. I can get it to run as low as ~5rpm pretty easily.

As I understand it, the manufacturer does not publish the RPM parameter for most of their drives allowing them greater flexibility in using whatever internal device the need to meet the performance requirements. I looked and cannot find it specified. My educated guess is 7200 RPM.

On the tool itself, maximum rpm is printed as 1300, which is what I think is correct. The literature says 3000rpm. I compared speeds with the PS10, which is 600rpm max and the PS11. Looking at them both running next to each other, the PS11 is about twice the speed as the PS10. So 1300rpm is the more accurate max speed for the PS11. I bought the PS11 for drilling because of the faster speed. I can drill a pilot hole with the PS11 and use the PS10 to screw in the fastener. They work well for me using them in tandem. Both are fine tools.

I have a 408windsor 425 hp. Had it cranked up to 4000 rpm. No worries no fears. Doesn't move with a quick pop on throttle either.

Hello, I need a motor to move slow. How slow would it rotate on the slowest speed? Thanks

It is a single range, variable speed. Also has torque settings for screw driving.

"Intellipower" RPM is intentionally not specified by Western Digital -- supposedly it is a *variable-speed* motor, I believe in the 5400 to 5900 RPM range. (They compare themselves on sequential reads to 7200RPM products, but mostly it's just a big cache and predictive algorithm responsible. On random reads, it won't compare so favorably.) Check out storagereview website for a full review of the WD20EARS, which uses similar basic drive internals.

Max speed is 3000 RPM lowest speed is 1300 RPM. These are approximate values given by the manufacturer.

5400 RPM, Not the fastest but it backs up all my stuff. I've had mine for over a year and it works fine.

25,000 to 27,000 rpm. variable speed through trigger. I use this for most automotive panel work and is great, I am not sure what John M is trying to use it for.

I think one of the responses was mis-stated. By my calculations if you use a standard 1700 rpm motor the mill would be spinning at about 4700 rpm's. If however you put the 3" pulley on the motor and the 5" pulley on the mill it would put you at just over 600 rpm's which is in the right neighborhood. A slightly smaller small pulley or a slightly larger large pulley may be more prudent.

I don't remember. Chuck fell apart after a few holes. I do not remember if it is variable speed but invariably it is a piece of junk. Ended up buying a small Makita for 200usd at HD. A lot better - still works.

Comes with adapter to be controlled by motherboard to achieve low RPM.. or just use a controller for speeds like 800 to 1500 RPM

It has two speed settings:regular and turbo. Don't worry you'll be fine. Braun is my favorite brand!

It doesn't have variable speed but it does have variable tourqe. I've used it for computer work and with the variable torque it never over tightens screws.

The RPM doesn't matter because it is a piece of crap. Don't buy it. You can't modify the speed, but most importantly it has absolutely NO torque. You can literally hold the arbor with your fingers to stop it from spinning.

The three speeds limit the max RPM, while the trigger gives you full variable speed control as needed. Brushless motor is great, too.
