Diamond Point Bit Set - worth having?
On my occasional stomps into Harbor Freight I've noticed a few different
Diamond Point Bit Sets and bought a set yesterday. I have a cheap dremel tool (B&D), and figure eventually I'll be glad I got the set. 20 piece, various tips for $8. Is this really a waste of $, or are these quite useful? What is your experience? What are they useful for? TIA. Dan |

What are they useful for? Cutting or sharpening materials too hard for ordinary bits. Vitrified ceramics, carbide tools, etc. |

What are vitrified ceramics? Are there any other uses? |

Sharpening is not just removing material, but maintaing a critical geometry. Masonry drill bits are feasible to hand sharpen with diamond wheels, since they have a very simple cutting point geometry. But twist drill bits require a lot of skill to hand sharpen. Saw blade teeth require very accurate angles and consistent spacing to get a decent result; they're so cheap as to be hardly worth the effort. |

I figure I'll find uses for them now and again. I thought of one today. I have a mug that was manufactured in a factory. I use it all the time (coffee), but it has a little ridge on the handle. I tried smoothing it off with a stone, but it wasn't too successful. the diamond bits are perfect for that - it's a glass mug. Dan |
