Thank you, for joining our Dremel Community.
The 9901HD Tungsten Carving Bit is for a Dremel Rotary Tool. Do you own a rotary tool?
To cut 1/8" aluminum sheet material, you can use a rotary tool with a Metal Cut-Off Wheel model EZ456. But the cut-off wheels will mainly cut straight lines.
Currently, we do not offer jigsaw blades or a metal cutting bit to make curve lines in aluminum.
Let me know if you have another question.
