A Rotary hammer when renovating an apartment turns out to be an indispensable assistant. When choosing a tool, it is important to take into account the specifics and scope of work for a hammer drill. A low-power hammer drill with a low impact energy coefficient is unlikely to "survive" a major repair associated with the hard work of making holes for sockets or widening doorways in concrete. But, with occasional work, such a tool may be quite enough.
Thank you for your work on this topic. I'm watching this because google is listening enough to recognise what I'm interested in now... "scary!"
Anyway, The impact drill I've been using for the last 25 years finally died. I usually purchase high end German manufactured equipment but was willing to compromise a little on this tool because it doesn't get a lot of use in my business outside drilling holes for nylon anchors in bricks or the odd punching through brick walls to run ducting. Ideally I wanted an inline style motor for getting into tight places but couldn't go past the extremely cheap and nasty Ozito brand from Bunnings.
I'm probably going to get frustrated at that choice down the track but I easily finished the 500mm x 30mm hole that killed it's predecessor and it came with a collection of chisels and drills that would probably cost the same or more than the meager $90.00 asking price if purchased separately.
I'm baffled that such a heavy 1000watt machine could be so cheap and be so competent.
We're living in strange times...
I wish I had seen this video a few months ago. I had used a workshop DeWalt 20v workshop battery hammer drill for drilling basalt rocks prior to splitting them. I had to start with a 3/16" bit and gradually work my way up to a 5/8". The drill would overheat and bits would spin in the chuck and I ended up replacing two chucks and going thro bits like no tomorrow plus hours of wasted time. It took hours to drill 4 holes to 5/8". .
I finally got smart and purchased a rotary hammer drill (cheap at $110- vertical motor) that was low on impact force (only 5.5J) but 1500 W. (corded). With this I was able to chew through the rocks with a single size bit (5/8") quickly with no downward pressure on the drill. With more Joules I am sure I would have conserved bits (expensive) and gone thro the rock more quickly as there lots of heat buildup and tips can mushroom even with frequent quenching.
It would be interesting for you to do a similar video on different drill bits in different drills. In my case I used Bosch and Milwaukee bits. I had better success with 4 cutter carbide bits from Milwaukee on my basalt rocks. poor boying the job by using the wrong drill for the particular job costs you plenty in drill bit costs. You end up paying now or later.
I am proof that getting the right tool for the job can save a lot of time and brain damage.
helps alot to understand before buying one thanks
Excellent video.
Thanks!
Best video ever!!
Thank you for appreciating my humble work!
I agree
@@CleverBill-DIY it's not humble at all dude, i think its great and informative
How much
This video keeps calling Rotary Hammer a Hammer Drill. Those are two different tools! Unlike Rotary Hammer, Hammer Drill cannot have hammer only mode due to its design.
