Custom Blades Showcase
Real Custom Profiles, Already in Production
From Our Production Floor
Circular Discs, Perforated Wheels & Gear-Tooth Cutters
Slitter discs, flanged wheels, serrated comb blades, and gear-form cutters — each ground to the customer's drawing in D2, H13, PM-HSS, or solid carbide, with every critical dimension CMM-verified before shipment.
From Our Production Floor
Flat Bars, Hook Blades & Sprocket Forms
Flanged plates, curved hook blades, bracket-form parts, and sprocket-tooth wheels — precision-ground special shapes produced from customer drawings or physical samples, no standard catalog required.
Custom Manufacturing
From Drawing to Finished Blade
Engineering Review, Not a Rubber Stamp
We Review Every Drawing Before We Quote It
Submitted geometry doesn't go straight to the grinder. Our engineers check it against the material and process first — if a tolerance, radius, or dimension isn't practically achievable, we raise it with you and propose a workable alternative before manufacturing starts, not after a rejected first article.
No drawing on hand? Send the worn or damaged part — we measure it on a CMM, produce a dimensioned drawing, and get your written approval before cutting any metal.
Every clarification is documented, so what we build always matches what you approved.
Material Recommendations, Not Just Material Options
We'll Tell You If a Different Alloy Will Outperform What You Specified
D2, H13, PM-HSS, and solid carbide each suit a different combination of abrasion, impact, and heat — and customers don't always default to the right one. Before we quote, we ask about your actual cutting condition, and if a different grade will run longer or cost less, we say so.
Sustained thermal cycling is steered toward H13; high-abrasion, low-impact cutting toward D2 or PM-HSS; the most demanding profiles toward solid carbide.
Every alloy is vacuum hardened and deep cryogenically treated in-house, regardless of which grade fits your application.
Inspection Support That Doesn't End at Shipment
An Engineer Reviews Your Results With You, Not Just a PDF
CMM inspection reports, hardness certificates, and material traceability ship with every order — but if a dimension or a field result raises a question, our engineers work through it with your team directly, and propose adjustments for the next batch if needed.
First-article orders include a First Article Inspection Report (FAIR), reviewed with you before full production is released.
Enhanced documentation packages available for customers qualifying us as a new ISO 9001:2015 supplier.
Profile Range
We Manufacture Any Custom Blade Profile
No profile is too complex. If it can be defined in a drawing, we can grind it. The eight profile families below cover the most common requests — contact us for any geometry not listed.
Looking For A Standard Shape Instead?
Straight Knives (Single / Double Bevel)
Single-bevel for shear-cutting, double-bevel for chop and impact cutting — the most common cutting-edge geometry on granulators and shredders.
Circular Disc Blades (Any OD / ID)
Slitting, scoring, and rotary cutting discs machined to any outer/inner diameter and bore pattern, for converting, paper, and film lines.
Serrated & Perforated Edges
Saw-tooth and perforated cutting edges that grip fibrous, rubber, or textile material during the cut instead of letting it slip.
Multi-Step & Shoulder Profiles
Stepped cross-sections that seat against a rotor or housing shoulder — common on proprietary granulator and shredder rotor designs.
Asymmetric Cross-Sections
Non-mirrored profiles for directional cutting action, produced from a drawing or reverse-engineered from a physical sample.
Hook / Hook-and-Tooth Forms
Curved hook geometry for tire, cable, and heavy-duty shredding applications, where the blade needs to pull material into the cut.
Conical & Tapered Profiles
Tapered cutting geometry for pelletizers and cone-type granulators, ground to a consistent taper angle along the full blade length.
Carbide-Tipped Composite Blades
A steel body with a brazed or bonded carbide cutting edge, for high-abrasion applications where solid carbide isn't cost-effective.
How It Works
Drawing to Delivery in 4 Steps
01
Upload Drawing or Send Sample
Share your DXF / DWG / STEP file via the form below, or ship a physical sample. We accept any format — even a dimensioned sketch.
02
Engineering Review & Quotation
Our application engineers review geometry, material options, and tolerances. You receive a detailed quotation within 1–2 business days.
03
First-Article Sample
We manufacture a sample batch with CMM inspection report. Approve dimensions, edge geometry, and hardness before committing to full production.
04
Batch Production & Delivery
Full production run with consistent quality. Every shipment includes hardness certificate, dimensional report, and material traceability.

Product FAQs & Buying Guidance
Technical FAQs
01What is the minimum order quantity for custom profile blades?+−
Our minimum order quantity is 1 piece. We accept single-piece prototype orders, first-article samples, and full production runs on the same manufacturing line. There is no volume threshold required to place a custom order.
02What does a custom profile blade typically cost?+−
Most custom and special-shaped blades fall between $20 and $800 per piece, depending on profile complexity, material grade, and order quantity. We provide an exact, no-obligation quote after reviewing your drawing or sample — there is no charge for a quotation.
03What drawing formats do you accept for custom blade orders?+−
We accept DXF, DWG, and STEP files as standard, along with PDF drawings and JPG/PNG photos of a sketch or sample. If you do not have a drawing, you can ship a physical sample or worn blade — we will reverse-engineer the geometry on our CMM and produce a drawing for your approval before manufacturing.
04How long does it take to receive a first-article sample?+−
Standard lead time from drawing approval to first-article sample dispatch is 5–15 working days, depending on profile complexity and material. Simple profiles in D2 or H13 steel typically ship in 5–7 working days; carbide-tipped, solid carbide, or complex multi-step profiles may require up to 15 working days — confirmed at quotation stage.
05What materials are available for custom profile blades?+−
We manufacture custom profiles in D2 cold-work tool steel (HRC 60–62), H13 hot-work tool steel (HRC 48–52), PM-HSS powder-metallurgy high-speed steel, and solid tungsten carbide. Material selection is matched to your cutting condition — abrasion level, impact load, temperature, and required edge life — at the quotation stage.
06Can you reverse-engineer a blade from a physical sample without a drawing?+−
Yes. Send us the worn or undamaged sample and we will measure all critical dimensions on our coordinate measuring machine (CMM), produce a dimensioned drawing, and submit it for your approval. Manufacturing starts only after you confirm the drawing is correct. The CMM report is included with the first-article shipment.
07What quality documentation is included with every custom blade order?+−
Every custom blade shipment includes: Rockwell HRC hardness test certificate, CMM dimensional inspection report confirming all critical dimensions and tolerances, steel mill material traceability certificate, and heat treatment batch certificate. First-article orders additionally include a first-article inspection report (FAIR). Enhanced documentation packages for ISO 9001 qualification are available on request.
Why Choose Sureay
01Is Sureay the actual manufacturer, or a trading company?+−
Sureay is a direct OEM manufacturer established in 2008. Custom and special-shaped profiles are ground and heat-treated in-house — no middleman markup, and you deal directly with the engineers producing your blade.
02What heat treatment do custom profile blades receive?+−
Every custom blade is vacuum hardened and then deep cryogenically treated, converting retained austenite to martensite. This holds hardness and dimensional stability consistent across even complex, multi-step profiles.
03Do you ship custom orders internationally?+−
Yes, we export custom and special-shaped blades to over 50 countries. First-article samples typically ship within 5–15 working days of drawing approval, depending on profile complexity; full production batches ship by air or sea freight depending on order size.
04What quality certifications back a custom order?+−
Sureay is ISO 9001:2015 certified. Every custom shipment includes a CMM dimensional inspection report, a Rockwell hardness certificate, and steel mill material traceability documentation.
