Circular Slitting Knife for Converting Lines
On a slitting or rewinding machine, blade quality is visible in every roll you ship: clean edges, no dust, no tear-outs. Our circular knives are ground flat and sharp with strict concentricity control, so the cut stays consistent from the start of the roll to the end.
Choose the material that fits your duty: SKD11 and D2 for general film and paper work, HSS for abrasive stock, tungsten carbide when run time between changes matters most.
Any diameter, bore, thickness and edge angle is producible to your drawing – and because we grind in-house, re-ordering the same knife months later gives you an identical cut profile.

Key Advantages
01Sharp, Stable Cutting
Strict concentricity keeps the blade true at speed, so edges stay clean without flutter.
02Steel for Every Duty
SKD11 and D2 for general slitting, HSS for abrasives, carbide for maximum edge life.
03Low Dust, Low Waste
A shear-sharp edge slices instead of crushing, cutting dust and rejected trim.
04Fits Most Machines
Standard and custom bore and pin-hole layouts for slitters, rewinders and converting lines.
05Repeatable Reorders
In-house grinding means your re-order matches the original profile exactly.
06OEM & ODM Support
From a worn sample or drawing to serial production with inspection reports.

FAQ
Which material should I choose?
SKD11 or D2 covers most films and paper; HSS suits abrasive stock; carbide wins where changeovers are costly. We advise from your material list.
Can you match my machine brand?
Yes – we work from diameter, bore and pin layout, so the knife fits slitters from any manufacturer.
What tolerances do you hold?
Concentricity and thickness are held to tight grinding tolerances; tell us your spec and we confirm feasibility.
Do you sharpen used knives?
Our core service is new knife production; for regrinding we recommend returning to your local tool grinder with our original profile drawing.
