> 24 hourI got these for my daughter, who has her own Dremel carving tool. I have use these for years as a favorite bit for starting a carving on various woods, gourds, and even tile, and soft stone. Great for other home repair projects too. They get the grinding done. Then a finish is made with high speed steel cutter, or diamond bit.

Recommendation: 1. Grinding welds, hardened steel, hard rock, a tool drive output of 300-500 watts is optimal. 2. For beginners pls choose more smaller burr head dia. than the holes’ dia. and swing-move the burr to enlongate holes, otherwise the burrs will chatter in narrow holes caused by not grabbing tool stably. 3. Gently press rotary tool, let speed do the work.
