Precision Paper Cutting & Guillotine Blades
Paper Cutting Blades
Guillotine paper cutter replacement blades in M2, SKH-9, and SKH-51 HSS or TCT (Tungsten Carbide Tipped) inlay for commercial print shops, bindery lines, and packaging converters. Precision-ground to 21° bevel with face flatness ≤0.05mm—delivering clean, dust-free cross-cuts on coated art paper, multi-layer board, and carbonless copy stock. Standard lengths 450–2050mm; length tolerance +2/−1mm, edge thickness 0/−0.1mm. HSS grades deliver 4–6× longer service life versus standard O1 tool steel—fewer resharpening cycles, lower press-room downtime.

Product FAQs & Buying Guidance
Technical FAQs
01Should I choose M2 HSS or Tungsten Carbide Tipped (TCT) blades for my guillotine?+−
M2 HSS is the correct choice for coated art paper, bond paper, and standard label stock in high-volume print shops — delivering 4–6× longer life than standard carbon steel. Upgrade to TCT (YG15/YG20 carbide inlay) only when cutting carbonless copy paper, high-calcium-carbonate packaging board, or abrasive specialty papers. TCT outperforms HSS 3–5× on these substrates but carries a higher unit cost.
02How does your blade geometry prevent dust when guillotining thick paper reams?+−
We grind every guillotine blade to a precision 21° bevel with face flatness ≤0.05mm across the full length. The sharp, shallow bevel shears each sheet progressively through the ream rather than crushing through the stack — dust is generated by dull or incorrectly bevelled edges that compress paper fibres instead of shearing them. HSS M2 and TCT grades retain this precision bevel geometry significantly longer than carbon steel, so fewer resharpening events mean fewer dust-generating dull-blade cutting cycles per year.
03Can you supply blades in the exact length and mounting hole pattern my Polar or Wohlenberg machine requires?+−
Yes. We stock standard lengths from 450mm to 2050mm to cover Polar 115/137/155/176/200, Schneider Senator, Wohlenberg, Perfecta, and Challenge series guillotines. Custom lengths, back-edge profiles, and mounting hole patterns are manufactured to drawing within 7 working days. Blades can be supplied sharp-ground, semi-finished, or blank to suit your on-site regrinding setup.
04How should guillotine blades be stored and handled to prevent premature edge damage before installation?+−
Store blades horizontally in original packaging on padded wooden cradles — never stack vertically or allow metal-to-metal contact on the cutting edge. Use plastic or rubber edge guards during handling. Inspect under a 10× loupe before mounting: a 0.2mm edge nick doubles local wear rate within the first 10,000 cuts. Avoid dragging the edge against guide rails during installation.
05Can you supply paper guillotine blades in semi-finished condition for in-house regrinding?+−
Yes. Semi-finished blanks are available in all standard lengths with the body ground to final dimensions but the edge left in pre-ground condition for final dressing to your specific bevel angle and finish. This supply state suits print shops with surface grinding capability, reduces unit cost by 15–20%, and gives full control over final edge geometry and sharpness.
Why Choose Sureay
01Are you a trading company or a direct manufacturer?+−
We are a 100% direct OEM manufacturer established in 2008. When you buy from Sureay, you bypass middleman markups and communicate directly with the engineers who forge and grind your blades.
02What makes Sureay's heat treatment different from cheaper alternatives?+−
Unlike standard quenching, every Sureay blade undergoes deep cryogenic treatment after vacuum hardening. This transforms retained austenite into martensite, boosting wear resistance by up to 40% and ensuring uniform hardness across the entire cutting edge.
03Do you ship globally and how long does it take?+−
Yes, we export to over 50 countries. Standard OEM replacement blades typically ship within 48 hours. Custom profiles take 10–15 working days. We partner directly with DHL, FedEx, and international sea freight forwarders for reliable door-to-door delivery.
04What quality certifications does Sureay hold, and can you provide material test reports?+−
Sureay is ISO 9001:2015 certified. Every shipment includes a Rockwell HRC hardness test report, a dimensional inspection record, and a heat treatment batch certificate. For OEM qualification, full CMM dimensional reports and steel mill certificates are available on request.
05Can we trial a sample set before committing to a full production order?+−
Yes. We offer sample sets (typically 2–5 blades) for machine fit verification and edge life testing. Standard sample lead time is 5–7 working days. For custom profiles, dimensional sign-off samples are produced before full production commences — no tooling commitment until fit is confirmed.
