Initially I thought I'd append this to my other thread but I figured, since most newer power tools boast of a variable speed control, I figured, maybe my new question would be could enough for power tools in general.
My understanding of variable speed controls on power tools especially cutting tools, is that apart from handling and care of the blade, bit, etc., it is also inorder to match your equipment with whatever material you're working on. e.g. speed x if you're working on material a, speed y if you're working on material b, etc., etc.
If you didn't have any better (cost, availability, etc.) options, would it be ok to just settle with a tool that doesn't have variable speed control?

Re: Power Tools' Variable Speed Control
true, you need variable speed for different type of material, ex. drill, if wood, high speed, metal low speed.....
Re: Power Tools' Variable Speed Control
i think most tools being manufactured today has the variable speed control specially for drills and even equipped with safety lock
Re: Power Tools' Variable Speed Control
If you do not have the variable speed control, then all you have to do is to vary your drilling technique in terms of frequency & pressure applied. Managing the heat of the drill bit and the material is of course the most important. Remember always use eye-protectors when drilling or using power tools !!
If you just use the drill once in a while, then you might get away with it, that is if you know how to basically handle a drill.
On the whole, entry level drills have a 2 speed trigger at the very least, but a variable w/reverse model is always the best
Now as a DIY'er, shouldn't you try using an old Singer Sewing machine foot control to ... never tried it but I wonder if it will work ????
Cheers ! 🙂
Re: Power Tools' Variable Speed Control
aah, yes, this may work fine with "trigger-action" tools like drills, where you just vary the manner by which you squeeze the trigger, but what about those tools which only have on/off switches?
;D singer foot switch... hmm... unfortunately we only have the old singer sewing machine at home which doesn't use electricity. ;D anyway, IMHO although DIYing a sort of speed control switch, like as suggested, to mod the tool, I believe most users, especially if the tool's still under warranty, would be wary in doing this.

Re: Power Tools' Variable Speed Control
The singer speed control is essentially a variable resistor, press your foot down and you compress carbon disks that reduce the resistance, putting more voltage into the motor.
The problem is that sewing machine motors are very low in wattage. Most drills will draw a lot more watts and may burn out the speed control.
Re: Power Tools' Variable Speed Control
i normally use 110 volts transformer when using drill for screws. u can buy screw bits sa hardware. even for roof screw, just check the wattage of your transformer to be safe. wala lang reverse!
Re: Power Tools' Variable Speed Control
OOO, never thought of that, using a tranny to bring the speed down. But do you have enough torque ?
And also, in the long term won't that be bad for the motor, the low voltage that is ?
Cheers 🙂
Re: Power Tools' Variable Speed Control
If your motor is a universal motor, I may have a variable speed control that comes from a electric drill or some other power tool. Sorry I don't have any specs except those of the tool it will have come from.
Re: Power Tools' Variable Speed Control
For cordless drill, it usually have variable speed switch, variable torque, reverse / forward switching, and hammer function.
Variable speed is now a common features of cordless powertools.
Cheers!
Re: Power Tools' Variable Speed Control
If your drill does not have variable speed and you need to drill something very hard like stainless steel the technique we use is to press the trigger on and off, on and off to keep the speed down, press for a while and the drill speeds up to the speed you want and to keep it from turning faster, trigger is released. This is repeated many times until hole is drilled. Low speed is useful for stainless steel. Drilling it at too fast a speed will burn the bit.
Re: Power Tools' Variable Speed Control
HI THERE GUYS.
ITS SO TIMING THAT YOU ARE TALKING ABOUT SPEED CONTROL.
WELL I HAVE A MAKTEC ROUTER AND I NEED A COMPATIBLE RHEOSTAT [SPEED OR VOLTAGE CONTROLLER] FOR IT.
IS THERE ANY READY ON THE MARKET RHEOSTAT THAT I CAN BUY SPECIFICALLY FOR POWER TOOLS ??
TNX
Re: Power Tools' Variable Speed Control
we may actually have the same router...
... do update me how this turns out... tia.

Re: Power Tools' Variable Speed Control
The regular speed control units are just light dimmers. You just need to find one that can handle the power rating of your router.
A way around not having speed control is to use your depth of cut. For hardwoods, make many shallow cuts. It is not quite the same thing but it should be ok.
