Hammer Drill Vs Rotary Hammer Drill And Why SDS Is A Must

hi guys and today i thought we would talk about drills for you know drilling into concrete so i basically have three examples here and i'm gonna explain to you guys why uh i ultimately ended up with this one in this bosch box so first off we have just a hammer drill as you can see this is a blue point one i don't remember where i picked it up from it wasn't bought from snap-on directly it must have came from a broad shell or something like that you can see it's fairly fairly new so typically how these drills work is there's a little bit of a hammering effect uh there's a kind of like a rotary style clutch in here that springs it forward and then back uh they work for small diameter holes you know something like quarter of an inch and lower this typically works fine but you're not going to chisel through something you're just going to drill with this and again once you start getting above a quarter inch depending on what masonry application you're drilling you're going to find that it could become difficult with this drill yeah so there's the uh blue point half inch hammer drill again i don't use it that much as you can see i'm typically not drilling small holes in masonry moving on i have this milwaukee actually that's the angle let's try this case [Applause] so here we have just a typical uh hammer drill again half inch chuck but this being that it's um a rotary hammer drill so basically that hammer drill the blue point one we use that uh like clutch mechanism to create the hammer effect here internally there's a piston so we can select on the top here between hammering or hammer drilling um this one also has stages on the side pretty simple there the biggest problem i have with this drill is the chuck it'll typically cut pretty good but seeing that's a normal style chuck you can see on this bit where the chuck spins around the bit so i'm gonna say part of that's due to the hammering effect rattles the chuck a little bit loosens it up but all in all i hated that you're constantly fighting with the chuck to keep the drill bit tight so that it doesn't spin in the chuck smaller applications maybe just hammering uh i would say would probably work again something around maybe 3 8 and below once you start getting up half inch size diameter stuff yeah it just spins in the chuck so i need to drill a lot of holes in concrete so this ended up yeah not working so i settled on a bosch hammer drill so oh let's see model r h 3 2 8 v c again we have our handle uh there is a depth gauge i was just doing pass-through drills so i didn't need that uh also i've used it to drill into barn beams uh later on may you guys will see that old barn i'm trying to restore but anyhow take that truck out of there it's a little bit different design a little bit more compact easier to handle of course you can get right on uh whatever you're drilling pretty easily this one also has a vibration dampener in this handle uh speed selection on the bottom pretty simple there on the side of course we can either go regular drilling like i said i was drilling barn wooden barn beams uh blast with it or you can do hammer drilling or you can do just hammering by simply you know turning this knob pretty simple there the biggest benefit to this drill again you've seen with the milwaukee the normal chuck here we have what's called an sds chuck so basically here we have an sds bit you can see alignment bar and then we have two holding uh spots in this bit so you put the bit in spin it around until it locks now it's locked in the chuck so the only way to get it out is to pull back on the chuck and then you can pull a bit out so there's no chance of the chuck coming loose and the bit spinning in the chuck as you can see there's locking tabs on the bit yeah for any type of hammer drilling you got you gotta go with this i honestly wish this kind of style was in normal drill bits because you don't have to screw around when tightening the chuck it always stays being spun so of course here's a chisel bit i used but you could say well that's great but i've got these other bits i've also also like to use so there's an option for that a three jaw adapter so basically sds on one side three jaw on the other side so this works great for uh the wood bits i've been using in the barn of course they're not as high torque and there's no hammering going on so your normal three jaw works fine for that so yeah anyhow i hope you guys found this video useful again if you're looking at doing a lot of drilling and above quarter inch i would definitely have to recommend a rotary hammer drill and one with an sds chuck i looked at a lot of competition price wise i ended up you know getting the bosch here so hopefully i can show you guys this in action down the road but for now thanks for watching and i will catch you guys later
