Drill reducer?

**Homercidal** · 04-07-2009, 05:42 PM

Anybody know where one could get an inexpensive speed reducer for a hand-held drill? I've tried Google, but I must not know what terms to use. I thought for sure someone would make such an item.

Dunno man... I bought a low speed 7.6 amp drill at Harbor Freight for my mill

I am willing to bet a keg of homebrew that you can buy a low rpm drill cheaper than any gear reduction set up. Just my two cents....

They are called drill speed reducers and they are used to slow the speed of a drill when using large diameter hole saws. They are an industrial item so finding one cheap is going to be tough. I actually have one I'd be willing to sell. It's a 2:1 ratio and has a 1/2" input shaft and a standard 1/2-20NF threaded output shaft. It's NOS in it's original box. PM me if you are interested.

Home Depot sells a right angle drive drill attachment which has a 2:1 gear reduction for about $20. I have one that I originally bought to use with my mill, but since then I acquired a gear motor that I'm now using.

Agree that a cheap low speed or VSR drill on a cord (not battery) will likely cost you less. Or you could set up a belt and pulley wheel system if you are into that sort of thing.

Well, the low speed would be nice, but more torque is what I'm after. I planned on using my dad's old 3/8 drill that's been around forever (rebuilt twice), but it's smoking after a few minutes. The largest problem may be the diameter of the crusher rollers. I built this crusher myself and had no idea how much force would be necessary to crush the grains.

Thanks for the offer, Figbash, but if I had my 1/2" drill running, I probably wouldn't need it. I have to rebuild the part that holds the brushed in place and never got around to doing it.

I'll look for that right angle drive reducer. I could use one of those around the house anyway. I have several motors on hand, but none are slow enough to consider using without much hassle, and I already have enough projects on my plate. For the brewing that I will be doing, it wouldn't be hard to hand-crank my grain. Or have my daughter do it...

Most low speed drills are high torque, because they have a built in gear reduction. That is what mine is.

It has an internal gear reduction, it is 7.6 amps, it will break your wrist...

Which one do you have?

OH, is it a 1/2" drive low speed drill from Harbor Freight... I love it!
