Is this normal for a masonary bit to look like this? (pics)

[NewShockerGuy]

Sorry.. this is lame I know but I am asking.

I'm drilling the garage this saturday for the anchors for the MaxJax...

I got a drill:

Got a decent drill bit I think:

The tip doesn't appear to be sharp at all... is this normal for a masonary bit?

I can't imagine this thing making a clean hole at all? Or am I wrong in thinking this?

Sorry if this is lame, but I don't want to get stuck with something and then on Saturday have it come out like ***... if I need to get other things please say so or recommend me to a proper bit?

Thanks much,
-Nigel

That don't look right at all.

I think it's fine. I've used masonry bits before and I don't recall any of them having a sharp tip.

Dunno -- looks OK to me. The drill goes through more by pressure than by actual cutting. That carbide tip plus the hammer drill should do just fine. I've had very good results from Bosch masonry bits.

 

[Skin]

that is a normal tip for an SDS-Plus bit. Its intentionally not ground to a fine sharp tip because the hammer action would blunt it immediately.

Totally normal masonry bit end. it acts more of a chisel in a circular motion then a normal wood bit.

Looks fine to me. As stated previously, it's more about crushing caused by the bpm than cutting. I wouldn't imagine you having any trouble out of it.

 

[FMC]

yup, its fine, make sure to start the hole on drill, on hammer they tend to walk off the intended target

 

[Wi Fire 10]

Looks just like it should. Its not supposed to be sharp. Just make sure to use the hammer function on that drill.

 

[MrMark]

Just so you are not confused, use the rotohammer function on that hammer. Hammer plus turning. Hammer only is for chipping. I have never used just the drill function that I can recall. One recommendation was to use drill first before switching to rotohammer. I have never tried that nor needed to do that but it may be good advice for some holes. I would just start slow on rotohammer. That hammer will blow through that concrete fast and with a perfectly round hole.

That is one mighty fine rotohammer and the best bit available.

 

[Chadwilliam1]

nope, its all junk send it to me and I will dispose of it properly.

This is a newer design drill bit. It prevents wandering on startup.
Works similar to the BD pilot point.

As Croc Dundee would say from Walkabout Creek . . . .

. . . . . now THAT's A Drill !!!


Be careful you don't drill deep enough to strike oil with that thing!! For just a few holes, you've definitely got the right tool for the job.

Good luck bolting down your lift . . . and . . post up pics when you're done.

I had to use one of those drills a few times to drill holes for running security camera cable, and I rather enjoyed it LOL

 

[NewShockerGuy]

Awesome, thanks all!

I was just like wow is this used? I was thinking it was going to be all pointy and sharp like a normal drill bit, then thought this can't be right, how the hell is a dull point going to make a nice clean hole..etc.

Good to know! This is the ONLY part I am not looking forward to is the drilling. But, we shall see!

Thanks everyone, will post updated pics once everything is all done.

You'll be amazed at what that Bosch will do with that bit. It's as easy as drilling wood.

 

[Automatic Slim]

should do the job shocker, make sure she stays level and get on top of her. don't forget to blow the hole and only drill anchor deep............


what type of anchor/fastener are you using?

 

[NewShockerGuy]

I'm using the wej-it ones that came with the maxjax pd-58. Everything I've read is to drill through the slab completely incase I run into problems I can tap it right through and do another. I bought a specific brush to clean the holes along with spraying air and vacuuming out the holes multiple times just to make sure they are clean.

I also got epoxy that I am going to coat the inside of the hole, and anchor... Set the anchor and then let it cure for 48 hours. There is a post where someone verified this was ok. I called wej-it to verify that they said there is no harm in using epoxy so long and this was stressed multiple times that you have to SET the wedge anchor BEFORE the epoxy cures, as it will do NO good to use epoxy if it cures and not setting the wedge anchor into the concrete. Which makes perfect sense to me. But I'd like both a mechanical bond and chemical... I understand that the epoxy isn't going to have a hold like if it was truely submerged in it, but it's extra measure to make sure that the anchors stay set.

I guess worst case senario if these don't work then i will go to a true epoxy anchor from hilti since they seem to get nothing but stellar reviews!

It's never lame to double-check. Like the others said, looks about right.

 

[Automatic Slim]

sounds good, i have used the wej-it anchors before with excellent results. the epoxy is a good idea as well, imo. don't waller out the hole, lol. Have fun w/ your new toy, sounds like a back saver.

 

[GShelton]

That is what I used to drill the 12 holes for my lift and it worked fantastically.

...This is the ONLY part I am not looking forward to is the drilling. But, we shall see!...

With this drill bit and a good hammer drill, you're likely to be delighted with the results. My experience with this combination in brick as been amazing. Like butter...
