Product Description
Engineered using premium black Silicone Rubber (SIR), it employs an advanced metal-overmolding process to integrate a stainless steel core with a flexible exterior.
The design prioritizes extreme dimensional accuracy, with hole tolerances maintained within 0.05mm to ensure secure bristle retention and prevent shedding during high-frequency vibration.
Delivers a high tear strength ensuring the base resists damage during the high-speed tufting process.
The silicone layer acts as a buffer between the motor driveshaft and the plastic head, significantly lowering operating noise.
