Keyway Drive Engineering & Shaft Stability
We manufacture every 170mm slitter blade with 20mm bore 6mm keyway to handle demanding torque loads without dynamic distortion or shaft slippage. Blade chatter and mounting slop degrade cut quality and wear out drive shafts. Installing a high-precision 170mm slitter blade with 20 mm hole locks your shaft setup in place and protects your converting equipment.
- Wire-EDM 6mm Keyway: Precision Wire-EDM keyway machining eliminates shaft play, key shearing, and rotational slippage under heavy torque loads.
- Vibration Reduction: The micro-ground 20mm bore maintains tight concentricity and runout (≤ 0.003 mm), eliminating blade chatter and side wobble at high operating speeds.
- Axial Balance: Balanced profile engineering prevents dynamic imbalance during continuous shear slitting on our industrial rotary slitting knives.
Material Selection Guide for Converting Applications
We supply each 170mm slitter blade with 20mm bore 6mm keyway in distinct steel alloys engineered for your exact line speeds, web tension, and substrate shear requirements. Selecting the correct material minimizes edge breakdown and slitter downtime.
| Material Grade | Hardness | Core Characteristics | Target Converting Applications |
|---|---|---|---|
| D2 / SKD11 Cold Work Tool Steel | HRC 58–62 | Excellent wear resistance paired with high core toughness | Standard paper converting lines, paperboard, and packaging materials |
| M2 / SKH51 High-Speed Steel (HSS) | HRC 62–66 | High red hardness and thermal resistance under extreme friction | High-speed film processing operations, polymer slicing, and edge-banding |
| Solid Tungsten Carbide | HRA 88–92 | Maximum abrasion resistance offering up to 10x edge life vs steel | Abrasive foils, metallic films, and continuous high-volume converting |
Deep Cryogenic Treatment for Thermal Stability
Every 170mm slitter blade with 20 mm bore undergoes an advanced deep cryogenic stress-relief process following vacuum heat treatment.
- Eliminates Internal Stress: Transforms retained austenite into stable martensite, preventing blade warping under severe operating temperatures.
- Preserves Axial Flatness: Prevents lateral runout shifts during high-rpm continuous rotary cutting.
- Tighter Grain Structure: Enhances edge retention so your 170mm slitter blade with 20 mm hole holds a razor-sharp profile significantly longer.
Whether fitting a standard 170mm slitter blade with 20 mm bore 6mm key way on a rewinder or an OEM shear slitting rig, matching material density to your material substrate guarantees clean, burr-free cuts.

Frequently Asked Questions
Why is a 6mm keyway necessary on a 170mm slitter blade with 20 mm bore 6mm key way?
A 6mm keyway provides positive mechanical drive transfer between the arbor shaft and the rotary knife. On high-speed converting lines, friction-only or set-screw mounting can slip under severe torque or thick substrates, leading to shaft scoring and dynamic misalignment. Installing a 170mm slitter blade with 20mm bore 6mm keyway eliminates rotational play, prevents key shearing, and ensures smooth shear cutting under continuous load.
How do I choose between D2, M2 HSS, and Tungsten Carbide for 170mm circular blades?
We select tool steel chemistry based on line speeds, substrate abrasiveness, and operational cycle targets:
| Steel Grade | Hardness | Key Advantage | Recommended Substrates |
|---|---|---|---|
| D2 / SKD11 | HRC 58–62 | High shock resistance & cost balance | Paperboard, standard paper, corrugated, packaging |
| M2 HSS / SKH51 | HRC 62–66 | High red hardness & heat resistance | Flexible films (BOPP, PET), polymers, edge-banding |
| Tungsten Carbide | HRA 88–92 | Up to 10x edge retention & wear resistance | Aluminum foils, abrasive non-wovens, 24/7 continuous lines |
Read our detailed technical guide on how to choose slitting knives to evaluate blade life versus material costs.
How does concentricity affect blade longevity and cut quality during continuous slitting?
Poor concentricity increases total indicator reading (TIR) runout, causing the blade edge to slap against the counter knife or anvil roll. This micro-impact accelerates localized edge chipping, causes material burring, and induces harmful drive shaft vibration. Every 170mm slitter blade with 20 mm hole we grind maintains concentricity ≤0.003mm to eliminate chatter and maximize blade life.
Can a 170mm slitter blade with 20 mm bore be re-sharpened or customized?
Yes. We manufacture and precision re-grind circular slitter knives to factory tolerances. Depending on total edge wear, each blade can undergo multiple re-grinding cycles on 5-axis CNC grinders without compromising bevel geometry. We also offer custom bevel angles (single, double, or compound), micro-serrations, and low-friction anti-stick coatings (TiN, Teflon) to meet specific web converting needs.
