Hello Everyone, a few years ago i bought a capri that was left in an ex engineers garage and in the boot was a big bag of these things (below) and i could not for the life of me, figure out what they was called? they look like they would be for drilling of something tough and the centre has a hole, which i assume is for jetting water through for cooling. any suggestions would be much appreciated. Thanks      |

It's a tip for an anchor drill used in mining.
Used for drilling into rock to insert anchor bolts to support roofs and stabilise rock.

Stone cutter tip with water going into the centre hole and debris plus water exiting up the threaded section is my guess.

Thank you for the replies. I did some googling using your answers and it turns out crockpot was right, they're for anchor drilling in mines ect. I'll try get back in touch with the original owner of the capri and see if he wants them back, as they're no use too me and after doing some googling, they seem to be expensive items to buy, so i'd imagine he'd of kicked himself trying to find them, if it's something he still uses. Thanks again. |

It's a tip for an anchor drill used in mining. Used for drilling into rock to insert anchor bolts to support roofs and stabilise rock. 👍 The pit I worked in used tips like that on the pneumatic boring machines that were used to bore holes for shot firing rock in development roadways. Water was fed down the middle of the drills (usually around 6ft long) and out the tip to cool the bit and minimise dust. Tips were usually carbide, like the ones pictured, brings back memories ... mainly of the dust and noise .... they weren't quiet, no silencers on them.  very little PPE in the way of dust masks / ear defenders around when I first started around 1969/70. Funnily enough by the time they shut the pit there was plenty  |
