Summa / Valiani Kiss-Cut Tool (KCT) is a specialized mechanical, spring-loaded tangential tool assembly designed to score or cut the top layer of pressure-sensitive material while leaving the release liner entirely intact

Blade Model	Summa art.no	Cutting Angle	Maximum Cutting Thickness	Description
Standard Tangential Blade	390-534	36°	0.25 mm	Ideal for general cutting tasks
Double Tangential Blade	390-551	36°	0.25 mm	Double blade for increased precision
Double-Wedge Tangential Blade	390-560	45°	1 mm	Suitable for thicker materials
Sandblasting Tangential Blade	390-550	60°	1.2 mm	Designed for cutting sandblast vinyl

Because Valiani is owned by Summa, their hardware lines share complete tool head engineering, making the Valiani KCT and the Summa F Series Kiss-Cutting Tool identical. Both utilize Summa T-Series Tangential Blades and rely on physical nose-piece depth regulation paired with manual spring pressure adjustments instead of digital software control.

Mechanical Design & Control Principles

Unlike standard drag or oscillating modules that use software parameters to dictate electronic force, the Kiss-Cut Tool uses a completely mechanical backup system to ensure it never punches through a backing liner:

Spring-Controlled Pressure: The tool utilizes interchangeable physical springs to set maximum downforce ranges. It ships with three distinct springs: 120g (thin vinyl), 650g (standard masking), and 1800g (heavy sandblast/magnetic foils).
Manual Micro-Dial Control: Fine pressure mapping is regulated directly on the tool head via a rotating manual adjustment disc.
Adjustable Nose Piece: A specialized contact nose piece (Part #395-348) glides along the face of your media, mechanically preventing the blade from plunging past your set micron-level depth.
