I got an SDS recently too. One of the first jobs I did with it
was sink an electrical socket in the inner leaf of a cavity wall. Using my old hammer drill, I would first pepper the area with holes and then excavate with a bolster. I've got used to the look and feel of this operation, so I no longer use a depth stop for the drilling. With the SDS, this was the first and only time I've so far used it as a drill rather than as a chiseling tool. So I drilled my hole as usual, and after a few moments all resistance disappeared. Oops - I'd drilled right through to the cavity, which is way, way deeper than you need to go through plaster into breeze block. And this was with a great big fat bit too. W. |

I spend a happy half hour when I got my SDS drill, turning a stone from the
rockery into swiss cheese. It was just so much fun to have somthing that goes through ANYTHING. -- Tony Collins "Woodspoiler" wrote in message ... I got an SDS recently too.

Andrew McKay writes: I'm sure some of you guys will have a laugh about this, but it surprised the heck out of me! I bought an SDS drill a couple of weeks back, never having used one before. And today I got to drill me my first hole in a brick. Nothing too magical there then. Since the day I've been drilling holes in bricks to take a rawlplug I've got used to my trusty Black and Decker with its hammer option taking a while to drill thru the brick, especially the hard-type bricks I happen to have in my walls around here. And I happen to have used fairly meaty B&D electric drills by domestic standards. However using the SDS drill with hammer mode was like a hot knife cutting through butter. I had a rawlplug sized hole sunk into the brick in seconds! I was literally gobsmacked! I always start with hammer off. If you hit mortar (particularly lime mortar) with SDS hammer on, you end up with a hole 3 times broader and 10 times deeper than you intended in less than a millisecond ;-) Also, I've had the occasional soft brick which drills fine without hammer, but shatters to a thousand pieces if an SDS hammer drill bit touches it. -- Andrew Gabriel |

Well I can't give you a definite "yes" to that question, but believe me, the bricks on our house were hard baked, and then apparently put back in the oven with some extra hardener added. With my B&D 650w "domestic" hammer drill, which I thought was the bees leg joints with respect to drilling holes, it would take absolutely 'kin ages to drill even a small sized hole. With my trusty new SDS 850w drill (which I admit I bought from a local Homebase shed because I needed a drill fast - cost £79) it seems that all I have to do is make sure the bit is positioned on the right mark on the wall, squeeze the trigger for a maximum of 3 seconds, and I've got me a hole into which a rawlplug fits. And the drill bit didn't appear to wander as it made the hole either. Now I have to admit this experience to which I relate equates to the drilling of two separate holes in the same brick. Just maybe I've picked the one brick in the whole damn house which was made of brick coloured swiss cheese - but I don't think so. The pile of brick sawdust which appeared on the floor sure as heck looked authentic to me. Andrew Do you need a handyman service? Check out our web site at http://www.handymac.co.uk |

DeWalt are living on past reputation in my opinion, and they should get back to what they were good at.

Actually, you've just made me wonder if on buying an SDS, might it be better off using the old hammer first, and switch to SDS when the going gets too tough for it. The thought I'm having is that you'd get it started gentler and possibly more accurate based on your comment above, and presumably conserve the life of both tools a little better too. Granted it'd be a bit more messing about to do it though. An SDS drill won't engage the 'hammer' action without pressure. So if you're unsure how hard the masonry is, start with gentle pressure. If the drill goes in as it will in soft material it won't damage anything. -- *I used up all my sick days so I called in dead Dave Plowman London SW 12 RIP Acorn |

I keep reading all these mentions of SDS drills and I still don't
know how an SDS drill is different from my elderly B&D Hammer thingy. Can someone please enlighten me of the ways in which SDS differs... SDS bits have channels in the side. You insert the bit into the drill by simple pushing it into the chuck while holding a collar back. The channels hold the drill very firmly so it doesn't slip. However, the bit is able to slide up and down in the chuck a fair amount, even if it can't slip sideways. The hammer action works by literally hammering the end of the bit, which is very effective because the sliding action means that the chuck can remain firmly attached to the motor whilst the bit flies forwards and backwards. A traditional "hammer" drill can't do this because the bit is firmly attached to the chuck, so it just wobbles it a bit from side to side, which is totally pants in comparison. Because the hammer action really does hammer the bit (quite hard if you push it) and is independent of the rotation action, it is usally possible to turn rotation off and put a chisel bit it. This produces a very useful demolition and chasing device! Christian. |

I think they have reduced everything Dave. The older ones we've had were great, really lived up to their reputation, that's why we went back for more after the years that the first ones lasted, but the ones we got last year were really poor in their power output. The build quality didn't feel right for an old style DeWalt, and they just sucked, really poor results with them. |

I've had plenty of shots with them and they do "do the job" They don't cost as much as the better known brands, but they should be given what's due for their quality. Really good buy one of those. |

On my normal hammer drill, the whole chuck assembly goes in and out. I reckon SDS works better in 3 ways:- The lower mass of the drill against a drill/chuck combination makes the impact greater even if the 'hammer' were the same. The impact mechanism is better - a hammer drill uses a ramp mechanism, and there's a limit to the acceleration that can be achieved. IIRC, SDS uses a pneumatic system. The SDS bit can't slip even slightly in a rotary direction. Feel free to add or subtract. ;-) -- *Before they invented drawing boards, what did they go back to? Dave Plowman London SW 12 RIP Acorn |

Yeah, the little guy inside an SDS drill is a lot stronger than the ones they put inside an ordinary drill, and they've got bigger hammers. They're that hard, that they eat masonry dust and drink molten grease. That's why the British ones are a lot better than most of the foreign makes. :-)) -- *He who laughs last, thinks slowest.

Had to laugh at yet more powerful, sorry yet more cells, 30V cordless keyless chuck drill being demoed live on QVC a week or so ago. Couldn't drill the concrete or cast iron because the bit kept sticking even after attempt at really tightening chuck. Quick cut to VT. A mid-range SDS drill can be had for about the same cost. Alan |

I can better that one! When I was young (I suppose about 12) our next door neighbour popped round and asked if he could borrow a chisel. Dad was in the RAF so wasn't around, so without thinking further I sorted out a nice wood chisel from Dads toolbox. The next day the neighbour returned the chisel which looked as though it might have seen better days. The neighbour explained that he'd managed to knock down his brick-partitioned parlour and thanked me for loaning the chisel. Obviously he'd wanted a cold chisel, not a wood chisel.
