Conical knife
Product Details

This knife will expand any hole with a precision of 1/10th mm by expanding both side of the hole, where a drill circles in one single direction and creates a spiral instead of a perfect hole.

it is pure iron ... It will work as well for plastics as in soft metals

Once you get use to it, you can't miss it anymore.

But, ... Please take care as it is very, very, very sharp.
