Is there such a thing as a right angle hammer drill or right angle sds
drill? Kevin |

Right Angle Drills
Kevin pretended :
Is there such a thing as a right angle hammer drill or right angle sds drill? Kevin No it would be a physical impossibility. Both SDS and straight hammer drill has to hammer in the same axis, in line with the bit. Not a bit of use hammering on the side. -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |

A percussion mechanism where there are annular steps and a corresponding opposing face as in many cheap hammer drills would be possible as long as the drive is capable of being made to right angles... Just AFAIK no one has actually bothered to make one or an adapter unit with hammer action. Whereas the hammer action of an SDS is a more mechanised version with pistons and sleeves in conjunction with an anvil device etc which would be near impossible to achieve at a right angle |

My understanding is that a hammer drill 'bangs' in line with the drill bit whereas the sds drill 'bangs' in the rotational element, no ? |

- show quoted text - IMHO sds are not hammer drills. My understanding is that a hammer drill 'bangs' in line with the drill bit whereas the sds drill 'bangs' in the rotational element, no ? /q Strewth GIYF if its how you imagine, how can you chisel with an SDS on 'rotary stop'? Jim K |

Right Angle Drills
fred presented the following explanation :
IMHO sds are not hammer drills. My understanding is that a hammer drill 'bangs' in line with the drill bit whereas the sds drill 'bangs' in the rotational element, no ? A straight forward hammer drill hammers using a pair of cogs facing each other, rather like the cogs in a ratchet. Pressure on the drill bit, forces the chuck to rise over each cog, then it is suddenly released at the peak. I'm not sure of the SDS principle of operation, but I understand a piston is involved, which thumps up and down in line with the chuck. A much slower hammer, but much stronger and more effective. I don't see how either effect can be turned 90 deg. My best guess is that the hammering is reproduced inside the Bosch gadget, from the drills rotation, much like inside a hammer drill. -- Regards, Harry (M1BYT) (L) http://www.ukradioamateur.co.uk |

The instructions show that it can be used with (and without) the hammer setting. You may wish to find another way to solve the problem, as this solution has a list price of 390.89 Euros.

No. SDS bangs in line with the drill bit, effectively with a small hammer hammering on the back end of the drill bit, and a chuck clamping mechanism which allows the bit to slide in and out in and out the chuck whilst being firmly clamped rotationally (so the chuck isn't involved in transmitting the hammer action to the bit, unlike a conventional hammer drill). -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

It would be interesting to see what rotation stop setting did if it didn't do as Andrew writes. -- Rod |
