Product Description
RawGasket™ – Perforated Vacuum Gasket for CNC
Designed for better sealing, more stable hold-down, and forgiving through-cutting
RawGasket™ is a 2 mm thick, perforated vacuum gasket sheet designed to create a tighter, more controlled vacuum surface on CNC machines. Placed on top of a spoilboard/vacuum table, it helps distribute vacuum more evenly and reduces leakage — giving you more reliable workholding when the workpiece doesn’t cover the entire surface, when cutting small parts, or when the setup isn’t perfectly flat.
In real use, this means more consistent vacuum hold, less “mystery slipping,” and a system that feels easier and safer to run — especially during contour cutting and through-cutting where small parts can otherwise start moving.

Perfect for uneven materials (like OSB)
Not every material is perfectly flat in the real world. OSB, plywood, and many sheet materials can have texture, voids, or slight warping that makes sealing difficult on a hard, perfectly flat surface. RawGasket is designed to be more forgiving in these situations: it helps compensate for minor unevenness and improves contact where the workpiece would otherwise leak.
The result is stronger, more stable hold-down even when your material isn’t perfectly smooth — without relying on complicated fixtures or excessive taping.

Through-cutting that lasts longer
RawGasket is a consumable surface, but it can last a long time when used correctly.
For through-cutting, the goal is not to cut fully through the gasket. Instead, set your Z-depth so you cut through the workpiece and only enter the gasket by up to about 0.5 mm. This gives clean cut-through while keeping wear to a minimum — meaning RawGasket can last a long time, even in repeated jobs.
This approach is especially valuable when cutting many small parts: you get clean through-cuts without “opening up” the system so much that vacuum stability drops.
Dense hole pattern for better control
RawGasket uses a denser perforation pattern than many industrial vacuum gasket solutions. In practical CNC use, this provides clear benefits:
- more active vacuum points across the surface
- improved stability for small parts
- more forgiving hold-down when the workpiece doesn’t cover a large continuous area
The holes are arranged in a straight grid pattern, making the sheet easy to:
- cut cleanly and accurately
- tile/combine in sections (tiling)
- use with CNC-friendly workholding that matches X/Y coordinates
This grid layout is chosen to match how CNC users actually think and work: repeatable coordinates, zones, and recurring setups.
Self-adhesive, modular, and easy to replace
RawGasket is self-adhesive and mounts directly onto a spoilboard. It can be cut to size and combined with multiple sheets to build up larger vacuum surfaces. When certain areas wear out, you can replace only the worn sections rather than the entire surface.
That makes RawGasket a practical and cost-effective solution for daily CNC work — especially if you switch between small and large workpieces regularly.
Flexible sheet size
RawGasket is supplied in 500 × 600 mm format, chosen to:
- reduce waste
- fit a wide range of tables
- make it easy to expand surface area by tiling multiple sheets
Every CNC table is different — so flexibility matters more than fixed “one-size” formats.
Material choice: sealing + friction + durability
The material is selected to balance:
- reliable sealing against the base surface
- friction against the workpiece
- durability and easy handling in a workshop environment
RawGasket does the same fundamental job as traditional vacuum gaskets — but it’s developed with real CNC workflows in mind: small parts, through-cutting, variable materials, and the need for more forgiving workholding.
