MSK-T-07 Compact Precision Disc Cutter with Four Hardened Steel Cutting Dies (15, 19, 20 & 24 mm) for Battery Electrode and Separator Discs
The MSK-T-07 is engineered to facilitate the precise manual cutting of circular discs from thin battery electrode materials and separator films, typically less than 30 micrometers thick. This tool is especially useful for battery researchers preparing samples for split test cells and coin cells, enabling consistent and accurate disc dimensions critical for reliable electrochemical testing.
Compact in design, the cutter fits conveniently inside glove boxes with a transition chamber diameter exceeding 230 mm, ensuring contamination-free sample preparation. Its robust stainless steel construction provides durability and resistance to corrosion, while the included hardened steel cutting dies ensure clean, sharp cuts across various disc sizes.
Key Features
- Four sets of hardened steel cutting dies included: 15 mm, 19 mm, 20 mm, and 24 mm diameters for versatile sample preparation.
- Designed for cutting thin electrode and separator discs under 30 µm thickness with high precision.
- Compact size suitable for glove boxes with transition chamber diameters larger than 230 mm.
- Major structural components made of stainless steel for strength and corrosion resistance.
- Cutting dies made of carbon steel; requires careful moisture control to maintain sharpness and prevent rust.
- Patent granted (201220296271.2) for the coin cell disc cutter design since January 2013.
- CE certified with optional NRTL certification available upon request.

Typical Applications
Ideal for preparing electrode and separator discs for coin cell batteries such as CR2016, CR2025, CR2032, and CR2450. The cutter supports precise sizing needed to avoid short circuits by ensuring separators fully cover electrodes. It is also useful for fabricating reference O-rings for three-electrode split test cells when using specific die combinations.
Configuration & Operating Notes
The standard package includes four cutting dies (15, 19, 20, and 24 mm). A special 24 mm outer diameter by 15 mm inner diameter O-ring cutting die is available as an optional accessory. Users should exercise caution when changing dies to avoid misalignment and damage. Cutting dies are sensitive to moisture and should be kept dry and clean. For cutting thin separators, placing an A4 paper underneath can improve cutting quality. Multiple cutters with pre-installed dies are recommended to prevent damage during die changes.
