Electric SDS breaker drill
Hi All.
I'm after a big SDS breaker for occasional concrete breaking. Probable infrequent use means that it is not really worth the expense of buying a premium machine (Bosch, Makita etc.). I am therefore tempted by the many and various 1700W to 3600W machines on eBay with neverheardofitbefore brands, all at around £100. A lot of the eBay machines seem to get good feedback from users (performance, durability etc.). The one consistently reported downside is weight (20-odd Kg). Any experience on here? Also, is more power likely to be the better option, or is 1700W plenty to break concrete, in most DIY scenarios? Thanks. Ant. |

I think it is mainly the weight that breaks the concrete, the power needing to be sufficient to lift it quickly enough. It did about 5m^2 of 4-5" unreinforced concrete without a great deal of effort and didn't fail then. I haven't used it since. Worth the £60 or so to avoid having to pay someone to do it. -- Roger Hayter |

Hi All. I'm after a big SDS breaker for occasional concrete breaking. Do you really mean SDS in this case? The larger 20kg breakers, e.g. something like: https://www.screwfix.com/p/titan-ttb...ker-230v/67819 Normally take hex shank chisels. The next size down (usually in the 10 to 15kg class) might be SDS Max There seem to be quite a few very similar looking machines about branded by any number of "own brand" names. IME they do a decent enough job. Probable infrequent use means that it is not really worth the expense of buying a premium machine (Bosch, Makita etc.). I am therefore tempted by the many and various 1700W to 3600W machines on eBay with neverheardofitbefore brands, all at around £100. Some years ago I needed something more destructive for a particular job and picked up a similar looking 20kg class machine from a local cash and carry. It works surprisingly well. Not much finesse about it, and it might not be a good choice for daily use, but for intermittent use it does get the job done. Only suitable for working downwards really due to the weight. A lot of the eBay machines seem to get good feedback from users (performance, durability etc.). The one consistently reported downside is weight (20-odd Kg). That kind of goes with the territory. With 45J of impact energy you need a certain amount of weight if you want most of that coming out of the pointy end, and not straight into you! Any experience on here? Also, is more power likely to be the better option, or is 1700W plenty to break concrete, in most DIY scenarios? I would say 1700W is plenty. 3600W etc is going to be difficult to run from an extension lead. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

Thanks All.
On the matter of the power, the potential difficulty in using a 3.5+KW machine with a regular extension lead was my main concern. If a 1.7KW is up to the job of dealing with most DIY breaking tasks, then I will probably stick with that. With regard SDS, SDS Max etc.- yes, I think I used the wrong term. It's a hex shank breaker that I'm after. Regards. Ant. |

As John says, weight is a problem if you were attacking a substantial wall or the side of a big concrete block, but you could suspend it from a tripod or A frame. For breaking a slab, you are relying on the weight and don't have to support it yourself. But isn't the best way to do a wall (unless it is a reinforced concrete motorway or something) to stitch drill a block,[1] and then use a moderately large but easily held jackhammer to break the mortar bonds block by block? [1]If knocking out a block with a big hammer is too destructive or ineffective. -- Roger Hayter |

For a "normal" wall you probably don't need a 20kg class breaker - they are really at their best for concrete slabs etc. A 10kg class SDS max machine will knock bits off a wall with ease. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

My ancient DeWalt lightweight SDS had no problems breaking up a concrete path here - after all you can lean on it if weight matters. Wonder if the OP has an SDS of any type? If you were regularly breaking up structural concrete, you'd likely be best with the appropriate tools. Which ain't going to be at cheap DIY prices. -- *Do paediatricians play miniature golf on Wednesdays? Dave Plowman London SW To e-mail, change noise into sound. |

For serious concrete breaking it is sometimes better to hire a big sod off breaker for the day. I have used budget SDS drill/breakers for small amounts but it becomes hard work after a time.

If you can lever up a bit of path so it is unsupported by soil, a modest whack will split it. -- Tim Lamb |

Routing a hose from the sump standpipe location in the coal hole out under the front door step immediately above proved ridiculously easier than I was expecting. :-) Murphy/Sod won't be having any more fun at my expense with heavy rainfall now, especially since my next door neighbour (detached from our property), let slip to my son that he's also been having basement flooding issues too. It's of some comfort to know that I'm not alone[1], both in regard of the "This Basement Is A Little Wetter Than I'd Like." syndrome, and the fact that Murphy/Sod has another "Playmate" to distract his attentions away from me.
