Got this Dremel Bit 561 off ebay.
It is a spiral cutter, the helix is reversed when compared to a drill bit.
A simple test run on a 5mm thick PVC sheet clamped to a vise.
However, holding it firmly, I managed to glide the bit smoothly across the sheet.
I suppose you can use it on thin sheets of acrylic or other plastic materials.
An alternative to a jig saw cutter.
It came in a packet of 3.
It is the one on the top.It is a spiral cutter, the helix is reversed when compared to a drill bit.
A simple test run on a 5mm thick PVC sheet clamped to a vise.
The round hole is what you get when you don’t hold it
firmly in your hand.
I pushed the bit thru the sheet and it wobbled like crazy…
should have held on to it tightly.However, holding it firmly, I managed to glide the bit smoothly across the sheet.
