iEcho E52 Decagonal (10-Sided) Rotation Knife Blades

The 10-sided geometry creates a continuous mechanical chopping and shearing motion as the tool moves. This prevents long fibers or multi-layered technical textiles from sliding or shifting out of the path of the gantry tool head.
Knife height: 32mm
Thickness: 0.6mm
Max. cutting depth:7.5mm
Knife type: Rotary
MATERIALS
Aramid fibers, Carbon fibers, Felt, Glass fibers, Non-woven fabric, Nylon fabric, Polyester fabric, Textiles
KNIFE/BLADE MOUNTING
hole Ø 8 mm
Tool Compatibility
The E52's 8mm mounting bore centers exactly onto the drive shafts of iEcho's rotation-specific modules:
- DRT (Driven Rotary Tool): Motorized rotation module that spins the blade in coordination with the machine's gantry travel speeds.
- PRT (Power/Pneumatic Rotary Tool): High-torque module meant to force the 10-sided blade through tough, heavy fabrics without bogging down the drive speed.
Ideal Material Applications
The E52 is primarily intended for processing tough, fibrous, multi-layered, or high-performance industrial textiles:
- High-Strength Composites: Carbon fiber plies, woven glass fiber sheets, and protective Aramid (Kevlar) fabrics.
- Thick Non-Wovens: Industrial acoustic felts, heavy carpets, and non-woven sub-straights.
- Synthetics & Heavy Textiles: Multi-layered polyester, nylon mesh, canvas, heavy tarpaulins, and dense natural leather hides.
- Packaging Paper: Heavy-gauge construction paperboards and flexible packaging sheets.
Production & Performance Options
When sourcing replacements, you can generally select from two main structural tiers depending on the abrasiveness of your materials:
- Standard Hard Metal (HM): Economical, untreated tungsten carbide providing clean shear dynamics for general print and textile production floors.
- DLC (Diamond-Like Carbon) Coated Variations: A dark, ultra-low-friction coating that lowers edge heat buildup. DLC coatings prevent synthetic materials from melting to the blade and double the operational tool life when cutting highly abrasive glass or carbon filaments.
