Easy cement/drill question

[rcurrier44]

I need to mount my bender to the floor of the shop.

When I picked up my hardware I also go a 3/4" cement bit. The hardware kid was quite addiment that I would need a hammer drill. Is this the case or will a normal drill do the job for 4 holes?

Any sugestions for making this work better/faster with a normal drill?

Thanks

Rent a rotary hammer.

hammer drill. rent or borrow. standard drill will just dull the bit. Hammer drill will get it done in 20 seconds.

rent a hammer drill. otherwise you will be there forever and probably not get one hole finsihed before you burn up the drill or the bit.

Harbor Freight has a 1' SDS hammer drill with bits for $39 on their online add. I have one and have used it for drilling holes in concrete, shaping stone and brick, demoing an old chimmney ,ect. It is a great tool worth many times the $59 I paid 6 or so years ago.

Dude you will spend and hour leaning on that 3/4" bit in a regular drill and then go get a hammer drill at the minimum adn take another hour or longer to drill the holes or rent a rotary hammer and be dont in 15 min. Hell I bought a makita hammer drill for 70 or 80 bucks and used it till it blew up probly 20 holes. then I bought a HF hammer drill for $40 to drill 6 holes and have beat the crap out of that thing and it still works great. but a good one from the rental yard wil make short work of your 4 holes.

Before I finally got a hammer drill I had drilled many holes with my good old regular drill, I'd just get the hole started and start slammen the drill it worked fine. Yes it did take longer but point was it did work.. I also kept some pouring water over the hole/drill as I was drilling.. (Yes hammer drill is a 10sec. job)

Sounds good

I just talked to our shop forman and they need to rent one to attatch some cushions to our loading dock anyway....so I will just wate until Monday when they do that and steal it to do my 4 holes too :)

Anyone make a 2" recever mount for their manual bender? I think it would work just fine but might be a bit sloppy.

Thanks

Get a 1/4in cement bit and drill pilot holes then drill the 3/4 holes, if you have a good heavy duty standard drill (not a Ryobi or the likes) then you can do it. Use an air gun to clean out the holes frequently as you drill.

hit a place like action rents or home deathrow the rent Hilti tool & real drill bits not the cheap bits they will do the job & not kill your shoulder if you want the ancor to last just use a peice of all thread & use the chemical anchor HIT-HY 150 Fast Curing Injection Systemsystem / AKA glue

Most Home Despots have a rental facility. Depending on the price, you may be halfway to the "Ebay" purchase price and a new Bosche 1/2" rotary hammer.

I picked up a Makita corded hammer drill (drill with hammer option) and it was $89 or so. I've used it alot. 1/2" chuck, side handle, depth guage, lots of torque.

Found it at Home Depot.

I've been putting up a new railing on concrete stairs and had to drill a lot of holes in cement. One side of the stairs had to be especially strong because it also acts as a post for a large fence gate.

What I used was 1/2" metal inserts. First you drill a 1/2" hole in the concerete, then you drive these inserts into the concrete. Then you attach whatever you need using "lag bolts" ... as the bolts drive into the inserts, the inserts spread apart and lock tightly into the cement.

I like this method because it's really strong and it's not permanent in that I can remove (in this case) the gate and railing if I needed to.

My advice in drilling into concerete:

... Hammer drill is a must, bits seems to last longer when I have a steady supply of fresh water to cool it as I drill. I just bought a cheap hammer drill.

... if you're drilling larger holes in concrete, the only wayI found to do it accurately and precisely is to use pilot holes. Ie: in order to drill a 1/2" hole to fit the metal inserts, I started with a 1/8", 1/4", 3/8" then 1/2". If you start with the 1/2" bit it tends to wander depending on the type of concrete you're drilling. You wprobably won't run into that problem too much on a shop floor though... This is mostly a problem when drilling into concrete with lots of rock filler

... DO NOT drill deeper than you have to or else the metal insert may be inserted too deel into the hole.

... Don't enlage the hole ... just make the hole wide enough so that the insert must be tapped in with a hammer.

Go to home Depot and rent a Hilti hammer drill and get the appropiate size Red Head anchor bolts for the job. You won't regret it. Lesser equipment risks ovaling out the whole not allowing the achor to grap properly.

Having both a 1/2" Makita hammer drill and a Hilti TE 25 I would strongly recommend waiting to borrow or renting the tool meant for the job.

The only reason the Makita looks new is because it is a replacement for the first one that blew up trying to drill 5/8” holes in cement to insert rebar to tie together an old slab with a new one. Just the difference in size should tell you one tool makes it a 5 minute job and the other is much longer.
