Festool stone drills

Were on sale to compliment my other set.

The first one is pretty big, are you expected to use those on the BHC?

Using these on a hammerdrill would be an exercise in futility. You wouldn't be able to apply enough axial force square on the bit to drill, without adding some sideloading and skating/drilling off your mark.

These would best be suited for a larger rotary hammer, which Festool doesn't sell, which is why I find it odd that they would even bother to rebrand these.

not if you use a pilot hole which I always would with these size of drills. Actually the Bosch is a (i think 1400 watts) rotary hammer drill, loud as hell if you use the rotary hammer action....

I don't see any drills, but I do see some very nice drill bits.

Nice collection there  ;D

Those drill bits wont fit in a PDC Drill.......the shanks on those bits are an SDS type fitting and will only fit in an SDS Drill....!!!!, such as the BHC drill for example.

If necessary they will fit the PDC Jacobs chuck.
It's not ideal but it fits like other round shaft drill bits, with a maximum of 13 mm.

  ???  ???  Really....?????? You must be joking, surely...!!!!!

 

[Slartibartfass]

Again these would be primarily used in the Bosch corded rotary hammer drill....

My 20+ year old 220v Bosch. It's 850w actually.

Also have a CXS.

I use a very long 20 mm SDS drill bit like that with my non-SDS hammer drill. Works fine. No slipping and no pilot hole needed. Can only use it for bricks though, my drill won't handle concrete with that size of a bit.

I drilled lots of holes with a Milwaukee hammer drill and never made a pilot hole.  The hammer drill was larger than the Bosche shown and i still have a 1-1/4" bit on the shelf in my cellar.  A bit warn from wear, but still useable.  I gave the hammer drill to my son many moons ago when i got out of the mason biz.  I don't know if the machine has worn out, but I still have a collection of bits for it.

I use the Bosch Xtream SDS bits in my 20 volt Dewalt hammer drill. No issues so far. And I drill ⅜ and ½ for Redhead Anchors.
On another note. I've used this drill for almost 3 years to mix Thinset Mortar.

I've used a Milwaukee 1/2" hammer drill for industrial and commercial work for 35 years.  I typically would drill 150 - 200 1/4" holes per automatic door installation 10-16 times a year plus repair jobs.  I had the gearbox rebuilt about 10 years ago and it still works great.  I rarely use it any more as mats and trim are not as prevalent now, and I use my Milwakee 12 & 18v cordless hammer drills most of the time.  For BIG hole and demo, I use a 28 year old Hilti TE-72.

I recently got a thing through the post from Festool showing their cordless range.
Anyway, one thing that they totally missed in that blurb which means a lot to tradesmen in the UK. They showed a BHC drill (Super, smashing, great, yada yada yada) but totally failed to mention that it was SDS compatible.

Now I don't know about anyone else but I'm a subcontractor, a fair percentage of my masonry bits are provided by the person/company I am subcontracting to.

I don't want to be forking out for fancy bits if the main contractor comes with a fixing that needs a funny size.

Now by the looks of it this drill is actually SDS compatible (thanks to the engineers at Festool no doubt) but unfortunately the feckless admen totally failed in their job. FFS mention SDS in the blurb.
Oh and some wally had photoshopped a drill bit onto the drill in the catalogue, unfortunately whoever it was (Stevie Wonder?) got the twist direction wrong as well.

Keep the engineers, sack the admen.

As I have been reading this thread, i have been wondering where i was lacking in my education somehow.  All this talk about SDS drills and bits had me in complete darkness. 

Sooo--------- I looked it up.

Origins of SDS Plus
The SDS drill system was originally designed by Bosch in 1975. The name SDS comes from the German “steck, dreh, sitzt” (insert, twist, fits). Bosch publicise the system on the international market as Special Direct System, although in German speaking nations it is more commonly known as “Spannen Durch System” (Clamping System).  I found out a whole lot more that i won't bother going into here.

I know all you guys who have been discussing this are aware of what you are talking about.  I WAS NOT.  I am sure that had these bits been developed long before i got out of the biz, i would have bought the drills and the propper bits.  My old rotary hammer drill (always Milwaukee when it came to masonry electric tools except a Hilty or two along the way.)  By the time i retired from anything to do with block, brick, stone and concrete in 1981, my old rotary hammer drill was already more than ten years old.  I feel much better now. [wink]

The first time I used an SDS drill after a normal corded hammerdrill it was an absolute revelation.
The hammerdrill needed loads of pressure and made a huge amount of noise and boy was it slow.
A more efficient way of converting electrical power into noise I have yet to see...

The SDS on the otherhand was not exactly quiet but it didn't half batter through bricks, concrete, granite, limestone.

Night and day difference.

My Rotary hammer drill was tough on my back.  It meant a trip to the chiropractor within a day or so if i spent more than an hour or so with it.  I used it for drilling hoes in concrete blocks and brickwork mostly.  I also used it where I had to break up small ares of concrete where it did no pay to rent a compressor and air hammer.  From what i have gathered from this thread and the info i just gathered on the internet, the SDS drills are miles better.

I will never use one, but it has been a great study.
