Blade cartridge Leitz 90310000 Grey Plastic Steel 14mm 40mm 48mm

The Leitz 90310000 blade cartridge is a precision replacement part for compatible Leitz Precision Office Trimmers. Constructed with a steel circular rotary blade housed in a grey plastic cartridge, the unit measures approximately 14mm in width, 40mm in depth and 48mm in height. Designed to trim paper cleanly and accurately, this cartridge handles up to around 15 sheets of A4 paper (80 g/m²) in a single pass when used with the specified trimmers.

Advantages

This blade cartridge combines a hardened steel rotary blade with a protective plastic housing to deliver consistent straight cuts while limiting direct blade exposure. The enclosed design supports safer handling and storage, and the cartridge format enables quick, tool-free replacement by dropping it into the trimmer head. The cartridge is compatible with Leitz Precision Office Trimmers designed for drop-in replacement, providing reliable cutting performance for routine office, classroom and craft tasks.

• Trimming multiple sheets of A4 paper (up to approx. 15 sheets of 80 g/m²)

How to use

Ensure the trimmer is compatible with drop-in cartridges and the trimmer head is in the open position. Remove the old cartridge according to the trimmer manufacturer's instructions, then align the Leitz 90310000 cartridge with the guide rails and lower it into place until it clicks or seats securely. Close the trimmer head and perform a test cut on a small stack of paper to verify alignment and cutting quality. Replace the cartridge when cuts become uneven or require additional passes to achieve a clean edge.

Usage recommendations

For consistent results, use standard A4 80 g/m² paper and avoid forcing the trimmer through oversized stacks beyond the stated capacity. Keep the cartridge dry and store the trimmer in a clean area to prolong blade life. If precise specialty cuts are needed, consider using the dedicated wave or perforating blade cartridges designed for the same trimmer series.
