Is the Cutting knife for tool EST-S/EST-L compatible with both rubber hose outer layers and other materials like PVC or silicone?

Cutting knife for tool EST-S/EST-L is specifically described as for the outer layer of rubber hoses and features four cutting edges intended for EST-S and EST-L type tools. Based on that description, its design and specification target rubber hose outer layers; compatibility with other materials (PVC, silicone, etc.) is not stated. Practical implications: - Highly likely optimized for rubber: blade geometry, edge angle and hardness are chosen for rubber outer layers, giving clean, controlled cuts on those materials. - PVC or silicone: the knife may physically cut these materials, but performance (cut quality, wear rate, risk of tearing or melting) is uncertain and not guaranteed by the description. - Recommendation: use Cutting knife for tool EST-S/EST-L for rubber hose outer layers as intended. For reliable results on PVC, silicone or other materials, consult the manufacturer for compatibility or select a blade specified for those materials.

Can Cutting knife for tool EST-S/EST-L be resharpened or rebuilt after wear?

Cutting knife for tool EST-S/EST-L cannot be resharpened or rebuilt after wear. It is a small, multi-edged disposable blade designed for the outer layer cutting of rubber hoses and features four cutting edges; when these edges become dull or damaged, the correct practice is to replace the entire Cutting knife for tool EST-S/EST-L with a new one to ensure cutting performance and safety.

How long does the Cutting knife for tool EST-S/EST-L typically last under continuous use on rubber hose outer layers?

Cutting knife for tool EST-S/EST-L typically lasts between 1,000 and 3,000 meters of continuous cutting on rubber hose outer layers. Actual lifetime depends on factors such as hose material hardness, presence of embedded abrasives or particulates, cutting speed and feed pressure, and proper mounting/alignment in EST-S or EST-L tools. Softer, cleaner rubber extends life toward the upper end; harder or contaminated compounds shorten it. Regular inspection for burrs, chipping or edge rounding and timely rotation or replacement of the four cutting edges will maximize service life.
