HSS or Carbide-Tipped Paper Cutter Knife for Polar Mohr Guillotine Machines

Product Overview

HY supplies replacement paper cutter knives for Polar Mohr guillotine machines used in printing, bookbinding and paper converting. HSS inlaid and carbide-tipped cutting edges are available. Each knife must be matched to the machine dimensions, mounting pattern and paper stock.

Cutting Problems and Selection

Rough edges, frequent sharpening and fitting difficulties require different checks. Review edge condition and blade material for cutting quality, and check blade dimensions and mounting holes for mechanical compatibility. Machine clamping and cutting-stick condition also affect the result; changing the knife alone may not resolve every cutting problem.

Blade Construction

HSS inlaid edge: an option for general paper trimming. Provide the paper stock and workload when selecting the steel grade.

Carbide-tipped edge: an option for applications where abrasive wear is a purchasing concern. Confirm suitability for the stock, machine condition and sharpening arrangements before ordering.

Ground bevel: confirm the bevel angle and finished dimensions against the existing knife drawing. Correct geometry and mounting details are essential to replacement selection.

Applications

• Commercial printing: trimming printed paper stacks to finished dimensions on a compatible guillotine.
• Bookbinding: cutting paper sections, covers and inserts, with blade selection matched to the substrate and workload.
• Packaging preparation: trimming suitable paperboard within the machine capacity. Provide board grade, thickness and stack height.

Film, foil and laminated materials require a separate application review.
