Why Buyers Come to Us

Six Problems Our Customers Were Trying to Solve

If any of these sound familiar, you are in the right place. Every Industrial Knives order is engineering-led, not a SKU match.

Premature edge failure

Catalog blades wearing out in days, not weeks. The wear pattern is usually diagnostic — material, hardness or geometry is wrong for the substrate.

OEM lead time too long

Maintenance windows measured in hours, not weeks. We hold buffer stock on common OD sizes and ship non-stock items in 15–25 working days.

Obsolete or vendor-locked parts

Original blade is no longer available, or the OEM has minimum-order quantities you cannot meet. Reverse-engineering from your worn sample closes the gap.

Inconsistent dimensional quality

Flatness, parallelism and concentricity drifting batch-to-batch. Every dimension you specify is CMM-checked, not just the ones that fit the schedule.

Unclear quotations

Quotes that hide tooling, setup or coating as extras. Our quotes list material grade, hardness, tolerance, lead time and tooling cost on the same page.

No engineering support

A supplier that just ships a SKU. Every Industrial Knives order has a named engineer — from RFQ review through to the dispatch paperwork.

Material Selection

Material and Tolerance at a Glance

Six grades cover ~95% of industrial cutting applications. Pick a row that matches your substrate, line speed and tolerance requirement —or send us your drawing and we will specify the grade against your process. Our quotation uses the Material-to-Tolerance Scorecard to align material, hardness and dimensional tolerance in one decision.

Blade material, designation, hardness, governing standards and typical use.
Material	Designation	Hardness	Governing Standards	Typical Use
D2	AISI D2 / 1.2379 / SKD11	HRC 58–62	AMS 6478 · ASTM A681 · ISO 4957	Cold-work tool steel. Default grade for paper, film and foil slitting; balanced wear resistance and toughness.
M2 HSS	AISI M2 / 1.3343 / SKH51	HRC 60–64	ASTM A600 · ISO 4957	High-speed steel for hot edges and abrasive feedstock — granulator rotors, high-speed slitting.
SKD11	JIS SKD11 / DC53	HRC 58–62	JIS G4404 · ISO 4957	Refined cold-work steel. First choice for thin-gauge slitting below 1 mm — reduces chipping risk.
H13	AISI H13 / 1.2344 / SKD61	HRC 50–54	ASTM A681 · ISO 4957	Hot-work tool steel. Used where shear heat builds up — high-speed guillotines and abrasive plate cutting.
6CrW2Si	Chinese GB 6CrW2Si	HRC 54–58	GB/T 1299	Shock-resistant grade for swing-beam shears cutting thicker mild-steel and stainless plate.
Tungsten Carbide	WC-Co (K10/K20)	HRA 89–92	ISO 513	Solid or tipped carbide for the most abrasive feedstocks — typically 8–10× the edge life of HSS.

Procurement and Engineering

Frequently Asked Questions

Eight questions our engineering team hears most often. If your question is not here, send it to engineering and we will reply within one business day.

Which blade material should I choose — D2, SKD11 or M2 HSS?

D2 (1.2379) is the default grade for paper, film and foil slitting at ambient temperature. SKD11 / DC53 is the first choice for thin gauges under 1 mm because its refined carbide distribution reduces chipping. M2 HSS (1.3343) is the right pick when the edge runs hot — granulators, high-speed slitting, or abrasive recycled feedstock. Send us your substrate, line speed and current blade life and we will recommend a grade on the quotation.

What tolerances can you hold on a custom blade?

Standard CNC grinding holds ±0.01 mm on flatness and parallelism, ±0.02 mm on concentricity and surface finish to Ra 0.2–0.4 µm. Tighter tolerances (down to ±0.002 mm) are available on request with a quoted lead-time impact. Every dimension you specify is CMM-checked and the report ships with the parts.

What is the typical lead time for a non-stock blade?

Stocked OD sizes ship in 10 working days. Custom non-stock items follow our 8-step process and ship in 20–25 working days from drawing approval. Reverse-engineered parts add 5–10 working days for the CMM measurement and drawing-approval stage. Lead times we quote are the lead times we deliver against — we tell you on the day we know if anything slips.

Do you offer reverse-engineering from a worn sample?

Yes. Send us the worn blade, a 3D scan, or a STEP / IGES / DXF file. We CMM-measure the critical features, reconstruct the original geometry, and propose a material and hardness upgrade where the wear pattern allows. A 2D / 3D drawing is issued for your written approval before any steel is ordered.

Which PVD coating should I specify — TiN, TiCN, CrN or DLC?

TiN is the general-purpose choice for wear resistance. TiCN suits thin film and paper where lower friction matters. CrN is used for corrosive or food-contact applications. DLC (diamond-like carbon) is the lowest-friction option for sticky or adhesive substrates. Coating thickness is held to ±2 µm uniformity and adhesion is verified per VDI 3198 on every batch.

Can you match an OEM part if I do not have a drawing?

Yes — that is the reverse-engineering workflow. We CMM-measure your worn part (or your spare), recover the original geometry, and either reproduce it exactly or upgrade it based on the wear pattern. The replacement is shipped with a 2D / 3D drawing of the recovered geometry for your records.

What is the minimum order quantity for a custom blade?

For a one-off custom blade the minimum order quantity is one piece. Tooling and setup are amortised into the unit price for low-volume runs. For ongoing consumption we typically schedule a quarterly batch (e.g. 20–50 pieces) so you receive a lower unit price and a predictable dispatch cadence.

How quickly will I receive an engineering quotation?

Within one business day of receiving your drawing, sample or written specification. The quote lists material grade, hardness, dimensional tolerance, lead time and tooling cost (if any) on the same page — there are no hidden extras. PPAP / ISIR documentation can be included on request for automotive and medical customers.

Quality and Risk Mitigation

Risk Reduction, Built into Every Order

Every batch carries a paper trail. Every dimension is CMM-checked. Every hardness is recorded. Here is what we do to keep risk on our side of the table.

Material traceability

Steel arrives with a mill certificate. We never blend grades and never substitute without written approval.

In-house heat treatment

Two vacuum furnaces and a cryogenic cell. Distortion is minimised through controlled quench rates; hardness is mapped on every batch.

CMM inspection

Every dimension you specify is checked on a coordinate measuring machine. Reports are shipped with the parts.

PVD coating adhesion

Coating adhesion is verified per VDI 3198 on every coated batch. Thickness is held to ±2 µm uniformity.

PPAP and ISIR documentation

Available on request for automotive and medical customers. Includes initial sample, dimensional and material reports.

ISO 9001 since 2003

Quality system audited annually by an accredited certification body. Documentation archive retained for ten years.
