The Handheld Precision Disc Puncher is an essential laboratory tool designed for precision circular cutting of battery electrode sheets and separator films. Engineered specifically for coin cell battery research (such as CR2016, CR2025, and CR2032), this manual cutter delivers clean, burr-free cuts to prevent short circuits and ensure reliable experimental testing.
Key Features
- Precision Cutting: High-hardness alloy punching dies deliver smooth, burr-free edges without tearing or deformation.
- Ergonomic Handheld Design: Compact, lightweight plier-style mechanism provides strong cutting leverage with minimal hand effort, ideal for use inside glove boxes or on open workbenches.
- Durable Construction: Wear-resistant hardened tool steel cutting dies ensure extended operational life and consistent accuracy.
- Versatile Sizes: Available in standard cutting diameters ranging from 11 mm to 44 mm, with custom dimensions supported upon request.
