Does an SDS Cordless Drill (Not Hammer) Exist? To Avoid Slipping Bits

I'm not a pro wrench. I use my tools for home repairs of myself and a couple rentals. My drill set consists of a cordless Mikita drill and a corded Bosch rotary hammer. The Bosch uses SDS bits and before I bought this a few years ago, I didn't know this existed.

My biggest complaint with my Mikita drill is the bits "slip" when drilling into something tough. The chuck loses traction on the drill bit and the chuck twists around the bit that gets stuck in the object I'm drilling.

Maybe this is an intentional safety feature? Like a governor that would prevent the motor from burning out because the drill bit isn't turning free enough in the object I'm drilling into. Or maybe it's a crappy chuck.

My SDS bits on the Bosch are incredible. I rarely use it compared to my Mikita because it's just for drilling concrete and block. But SDS seems like it couldn't slip. I can't find any SDS based regular non-rotary drill tools.

I understand that SDS bits are significantly more expensive than regular drill bits, and bits are meant to be disposible to some extent. But as a handyman I don't find myself wearing out bits enough that cost would be an issue.

Does an SDS cordless drill exist? I saw Bosch makes a compact cordless rotary hammer but that looks like overkill and too heavy for regular handyman drilling stuff. Perhaps I can replace the chuck on my existing Mikita or buy another cordless drill that allows a different chuck? My Mikita was a consumer grade, I didn't know better at the time and am open to buying a nicer one.

Or maybe it's not the tool and my technique is wrong and the drill bits are supposed to slip as a safety feature? Because maybe I'm using incorrect setting, incorrect pressure, incorrect bit, dull bit, not powerful enough drill, etc?

Do you just use the trigger to tighten bits in the chuck? If you do, try cranking down by hand afterwards. You can usually get a few more clicks and prevent slipping. If that doesn't work you could always swap the keyless for a keyed chuck for very little money or upgrade to a nicer keyless for a bit more cash.

Most have a drill only function; the smaller 1" ones are fairly light & ergonomic for what they are.



This..

I have a 20v cordless dewalt sds plus and its an awesome tool

They have 3 modes

Chipping hammer mode

Straight Drill mode

Rotary Hammer drill mode

You will never drill in concrete or masonry with an ordinary hammer drill again

They even have adaptors to convert the sds plus to a regular drill type collar to be able to use regular (non sds) drill bits

Interesting! So some of you actually use a cordless rotary hammer as a drill, instead of having a dedicated cordless drill?

You don't find the added weight/bulk an issue?

I VERY rarely have to drill into concrete. Maybe 3 to 4 times a year, and 1 to 3 holes each time. So that's why I got a dedicated corded rotary hammer because it's so rare to need it, I don't mind lugging it out when it is.

But I do use a regular cordless drill about once or twice a week. So I'm worried a cordless rotary hammer, even a compact one, will be not fun to use as a cordless drill for the 99% of the time that's all I would use it for.

Or you could just buy a set of drill bits that have flats on them. A lot of them do these days for the larger sizes at least.

Any time I am drilling concrete/block/brick/stone, I use the sds. Trying to use a hammer drill after using sds feels like tickling the concrete with a feather. So much faster to use the sds, even thou it's slightly heavier. Sds come in different sizes, my makita cordless one is fairly compact, but I have a big one for drilling cores.

I don't use sds for drilling wood or metal. Do your chuck up tighter and sharpen your drill bits.

Pending size of hole and material sometimes keyless chucks and cordless drills just don’t cut it. A slow speed corded drill with a keyed chuck and a quality set of drill bits will change your world.

Check out the corded Milwaukee magnum drills in the low rpm with keyed chuck and buy a set of Norseman or equal drill bits.

Using a cordless sds to replace a cordless drill for everyday drilling would be terrible. No question about it.

Figure out how to tighten your chuck properly. You shouldn't be having that much of a problem with bit slippage

Most brands have a cordless SDS drill, including Makita. I have a Panasonic, and it works so well I got rid of my corded Hilti.

However I've never had problems with drill bits slipping in my Makita standard cordless drill. I've found the chuck to be exceptionally good. I'm wondering if you are tightening the chuck enough - you have to turn it until it clicks tight a few times.

This is the correct answer. The only bits I have seen sold with SDS shanks have been masonry bits. Even "multi-material" bits are not made in that format.

So, if the OP's plan is to use an SDS shank bit to drill wood or metal, good luck finding the bit set for that purpose. Hint: it does not exist.

Good tips thanks all! I have seen drill bits with some hex heads and I think they were part of some Quick Detach system but should work great for my needs.

And I can't believe it but I didn't know about using hand tightness to secure the bit on the keyless chuck. I would always just hold it with my hand and press the trigger to tighten or loosen it. I had a few holes to drill last night and I did get a short hand turn afterward until it clicked. Didn't go far, maybe 1/50th of a turn, but that might be good enough to keep things from slipping!

Is there such a thing? I've seen decent drill bits with three flats ground on the shank, but all of the hex shank drill bits I've seen are fare from decent. Those are the cheap drill bits I hand my wife when she wants to hang a picture on the plaster walls and needs to pre-drill for an anchor.

As stated before, just replace the chuck. A good chuck should spin you before it lets go of the bit.

Either your chuck is worn, or your drills are exceptionally soft. Make sure you crank the chuck down hard by hand, against the locking mechanism of the drill (when the trigger is released).

If that still doesn't work, the best solution is to replace the chuck. You could try a Yukiwa from a higher-end Makita. Many people like the aftermarket Rohm chucks.

There are decent bits if your used to what you buy at the big box store. But it sounds like run out can be an issue from all the different brands, just a matter of getting lucky with the set you buy on any given day. But I haven't seen anything that might compare to a real quality drill bit.

is a few decent ones if look, not machinist quality but up to pro odd job use.
Masonary and wood easy find but hss also can be had if move on past box store low end stuff .
More about in 1/4 hex these days due to impact drivers .

But they do. As do adapters to a normal keyed chuck (tho that's back to step 1, although generally a non-slipping chuck).
