IncogRa Posted December 22, 2017 Report Share Posted December 22, 2017 Ok, so i am a computer nerd, i dont knownalot about tools but my dad is wanting to grt a new drill so i figured i would get him one for christmas, i found out as much info as i need i think, but im a little confused on the chuck sizes, now from what i have red drills come in 1/2, 1/4, and 3/8 sizes, whiches one do i need? He uses this mainly for household items with wood primarily, does the chuck size effect what size bit i can put in the drill? Tbh i dont really even know what a chuck is... so if i grt any of this wrong please inform me, thank you Quote Link to comment Share on other sites More sharing options...
jtkendall Posted December 23, 2017 Report Share Posted December 23, 2017 The chuck is the opening that accepts the bits on a drill, 3/8” and 1/2” are the most common in the US for everyday use. My opinion is that you want a 1/2” chuck always, because it can hold up to a 1/2” bit and every size under 1/2”. 2 Quote Link to comment Share on other sites More sharing options...
Stercorarius Posted December 23, 2017 Report Share Posted December 23, 2017 It's the max diameter of the bit's shank. 1/2" would be best, 3/8 would be fine. Both can drill holes larger than their chuck size. A bigger Chuck = bigger holes. Quote Link to comment Share on other sites More sharing options...
fm2176 Posted December 23, 2017 Report Share Posted December 23, 2017 The 1/4" size you refer to are likely impact drivers or screwdrivers designed to take 1/4" hex shank bits. While there are drill bits with hex shanks and some people do use impact drivers as drills, your dad will probably be best served with a regular chuck. As for chucks, they are the device which holds the bit, usually comprised of three inner jaws and with an external sleeve that is hand tightened (most users power the drill to speed things up until it is snug) to hold the bit in place with the jaws.

Eric - TIA Posted December 24, 2017 Report Share Posted December 24, 2017 Agree with them above, the 1/2" would be the way to go. It's better to have the bigger size and not need it, then need it and not have it. 2 Quote Link to comment Share on other sites More sharing options...
