Industrial Keyway Circular Slitter Blades | Custom Rotary Round Knife Factory

As a local industrial blade manufacturer, we craft custom flat circular rotary knives with built-in keyways, built to work across packaging, nonwoven textile, rubber, plastic film, paper, and textile processing lines. Each blade is forged from premium SKD11 or SKH-51 steel, then fine-ground on one side to tight tolerances. This precise grind cuts down material waste on every run and helps each blade hold its sharp edge far longer. We gladly build blades to match your physical samples or engineering drawings, and handle full export logistics to simplify orders for overseas buyers all over the world.

Ganzhou Big Brother Cutting Tools Co., Ltd. handles in-house development, manufacturing, and custom machining for industrial cutting tools and non-standard knife molds. Our full product lineup covers packaging machine cutters, food processing blades, wood alloy planer knives, shredder blades, agricultural cutting tools, plus custom precision knife molds. We supply ready standard blades for bulk orders, alongside fully tailor-made cutting tools built to unique factory requirements for global customers.

 Why Choose Our Keyway Circular Slitter Blades

Built-in key slot at the inner bore locks tightly with the machine spindle, effectively preventing blade slipping and size deviation during high-speed continuous slitting, guaranteeing a consistent cutting width.

2. Premium Steel & Precise Grinding

Adopt SKD11 alloy steel or SKH-51 high-speed steel, hardness up to HRC 58-62. Single thin bevel edge provides smooth burr-free cutting surface with narrow kerf.
