Summa 500-9810 9811 9812 9813 9814 9815 F Series Electronic Oscillating Tool(Eot)Vinyl Plotter Knives Knife Blades

The designations you provided—Summa 500‑9810, 500‑9811, 500‑9812, 500‑9813, 500‑9814, and 500‑9815—refer to replacement oscillating knife blades specifically designed for use with the Summa F‑Series flatbed cutters. These blades are compatible with the Summa Electronic Oscillating Tool (EOT) and its corresponding holder, most commonly identified as SUM‑500‑9320.

Details about these part numbers:
Each of the six codes (500‑9810 to 500‑9815) corresponds to electronic oscillating knife blades (EOT knives) intended for use with the Summa F‑Series EOT system. These blades are installed in the same EOT holder (SUM‑500‑9320) and are suitable for cutting various soft to medium-density materials. These include corrugated board, foam board, magnetic film, felt, fabrics, rubber, and other similar substrates.

Part No.	Knife height (approx.)	Angle range	Typical use / max thickness (approx.)
500-9810	L25 / ~25 mm	63°–79°	Up to ~11–14 mm; corrugated, foam board, carton, magnetic foil, etc.
500-9811	L25 / ~25 mm	65°–85°	Common default EOT knife; ~0.20–0.43 in (5–11 mm) with/without gliding disk.
500-9812	L28 / ~28 mm	65°–85°	Slightly taller than 9811; suited for thicker soft/medium boards.
500-9813	L25 / ~25 mm	0°–65°	Lowangle knife for shallower or more controlled cuts.
500-9814	L33 / ~33 mm	45°–86°	Deepercut knife; up to ~95 mm (without gliding disk) in some FSeries specs.
500-9815	L33 / ~33 mm	45°–85°	Similar to 5009814 but with a slightly different angle range.

The connection between these tools and vinyl plotters or signage lies in their specific functionality and application. Unlike traditional vinyl drag knives, which are commonly used for contour cutting on standard vinyl plotters, EOT knives are specialized oscillating flatbed tools designed primarily for Summa F-Series flatbed cutters. These knives excel in handling more diverse and robust materials, such as those used in signage, packaging, and various industrial applications.

In contrast, for the traditional process of contour cutting on regular vinyl, drag knives or tangential-module cutout knives are typically employed. For instance, Summa's 500-9802 series represents a common choice for such tasks, whereas the 500-9810 to 500-9815 series includes equipment geared toward slightly different purposes. That said, the versatility of Summa F-Series machines allows them to accommodate multi-tool configurations. This capability enables users to integrate both types of tools—oscillating EOT knives and drag or tangential knives—on the same machine, broadening their operational flexibility and efficiency.
