How the Flexible Shank Unlocks Every Corner
Think of the flexible shank like a bendy straw for your rotary tool—while a regular burr is rigid, the flex shank gently curves, letting you reach odd angles as if you had an extra wrist. This flexibility is ideal for working on castings and detailed surfaces where traditional straight shanks just can’t reach without awkward maneuvering.
It also reduces strain on your hand and tool, making longer jobs easier and more precise. So when you need to work beyond the obvious edges, this flex shank is your secret weapon.

Setting It Up
- Ensure the rotary tool or flex shaft machine is unplugged before installation.
