Why Use It?

Anyone who has cut PTFE tubing with side cutters or scissors knows how easily the tube can deform, resulting in angled or crushed ends. The Guillotine V2.0 produces consistent, square cuts that improve fitment and overall quality.

The adjustable stop makes batch cutting fast and repeatable, while the interchangeable inserts help keep smaller materials properly centered during cutting.

This tool saves time, improves precision, and makes repetitive cutting tasks significantly more efficient.

Safety Notice

This model uses a sharp utility blade. Always handle and assemble the tool carefully, keep fingers clear of the cutting area, and store it safely when not in use.
