Milling: Difference between revisions

For most home brewers a drill is the preferred method to drive a mill. It is easier to set up and more economical than using a non-drill motor, and significantly less laborious than hand cranking. Low RPM drills provide the best torque. We don't recommend using an external speed limiter ({{Amazon|B00U3LD1WA|example}}) on a high RPM drill because they significantly reduce the torque.<ref>[https://www.homebrewtalk.com/threads/speed-controller-for-corded-drill-used-for-milling-grain.629645/ Speed controller for corded drill, used for milling grain?] Homebrew Talk website. 2017.

A corded drill is generally more powerful than a cordless one, and will usually last longer. However cordless drills can also work well, and they are more convenient for tasks around the house.<ref>[https://www.beeradvocate.com/community/threads/need-drill-recommendations.581479/ Need drill recommendations.] BeerAdvocate website. 2018.

Accessed 2020.</ref> The one requirement to using a drill is that the drill chuck fits onto the mill drive shaft (which range from 3/8" to 1/2" [9-12mm]). If you are holding the drill while milling, you must also hold down the base of the mill. Otherwise the torque may cause the mill to flip over, causing damage and/or injury.
