Do you need to grease SDS rotary hammer drills?

This question comes up pretty often, so I made a video about it. But how to not make it as dull as dogshit? Slow Mo footage!!

Thank you!

[@tobyorchard8798]

Killed me with that Hitachi line!

[@BoltahDownunder]

Yeah I hear they use them for massaging or something? seems a little rough for that

[@jordanalexander615]

I don't see Hitachi here in the US anymore. It's fused with metabo even reusing the same case mold designs from ten years ago.

[@bayadere8308]

Hitachi has been called Hikoki for a few years now, after the merging.@@jordanalexander615

Same i chortled out loud

Well, one thing is for damn sure. I got a drill bit absolutely stuck in my el cheapo rotary hammer. Won't come out without an angle grinder. No, sir! Funny thing is the drill bit was damn near as expensive as the rotary hammer. BTW, expensive drill bit with a cheap rotary hammer might be as good (or better) than a cheap-ass drill in an expensive rotary hammer. And, do NOT overheat the drill bits or the solder will soften and the hard bits will come off and the drill bit is done. You need 2-3 drills and swap them after every hole.

[@MakersGonnaMake]

Perhaps you could, like me buy brake grease or rubber grease which is compatible with plastics usually a Vegetable-oil based grease

thanks

"How long is a piece of string?" Excellent!

[@jordanalexander615]

Every cordless rotary hammer leaks grease when it gets hot that we have brand didn't seem to matter. Makes a mess slinging it around. Don't really know why it's not sealed very good.

[@BoltahDownunder]

It's probably helpful to have a bit of the internal grease leak out past the striker pin at the back of the chuck, so that's probably what Milwaukee etc were relying on when they don't mention greasing it but getting it serviced. But when it leaks out of the mode switch or body? Yeah that's just annoying

[@jordanalexander615]

@@BoltahDownunder mines leaking out of the pull back you use to take the bit in and out. So then its rotating at a high speed and slings it everywhere.

😲😱😲😱🤔 you greseseed you drill same week as i opened n flused out my sds makita drill from cash con..180$$ 18v . 242dhr. Used unleaded fuel.. good as new .. open via the selectorrr ..knobb.

[@mvmcali6900]

Margeret. she was a lovely hammer 🙂

[@notastepizzaface]

Many other videos say to take off the selector knob and grease in there. Do you not do that?

[@BoltahDownunder]

Yeah you could but that type of thing is more like an annual service rather than just general usage. Personally if I were worried about the gearbox/hammer mechanism needing grease I'd open the whole drill up & clean the old grease out before adding new stuff. The reason being you shouldn't mix different greases unless you know what type they are. They can react & dry out, which drops the oil & leaves the thickener behind. If you're not sure it's best to leave the insides of your tool to the service department

[@sethmarshall]

Thanks. I went ahead and did this to mine because Im not sure when it was last done. @@BoltahDownunder

[@DwayneDibbley]

Have you ever done a comparison between a double cutter and quad cutter bits? do they make a difference - cheers

[@BoltahDownunder]

I'm making one actually

[@istopedthewuhanlabfunding6351]

Ha mate .. the makita only gose slow or full BORRRRE . Can you tell me of a 18v sds that dosnt only have 2.3 speeds . I need the full 12 gears . VARIABLE for the granite . Coss its eating up drill tips like crazzy

[@BoltahDownunder]

a couple of drills have like a 70% power setting to start up slow...hikoki dh18dpb Bosch GBH18V-26... But maybe you want to try wet drilling with the Rotary hammer? That can keep the bits running longer. Or core drilling?

[@istopedthewuhanlabfunding6351]

I gotta try out an old 24v dyna link sds drill. But the trigger is 💥😨 . So Alix is has got 1 .. gotta wait postages.. china ..👍

[@istopedthewuhanlabfunding6351]

Looks like its the makita .. knock off they make .. Back in old days .. It was ment 2 be .. Dump shop love .

[@istopedthewuhanlabfunding6351]

Can you make a short vid on .. VVVARI ABLE sds rpm ..drillings..🇦🇺👍🤔

[@istopedthewuhanlabfunding6351]

Just got a full bore bunnings 2000w core drill now .. so rocks 💪💪watch OUT 💥

[@permapunter]

Good, but have you thought about dialing up the slo-mo even more ?

[@BoltahDownunder]

You mean slower or using it more? I've got some footage going into things here and there, but really when trying to show something specific not just looking cool. So far

[@A7Self]

Can too much grease damage the drill?

[@BoltahDownunder]

Damage? No not really. The grease falls out when drilling. Bit get the bit stuck? Yes it can create vacuum if you have too much grease, drill and then allow to cool with the bit installed

[@andyhedges5705]

Wives generally use a different sort of Hitachi.
