Uncoated, ultra-hard tungsten cemented carbide inserts — engineered for consistent surface finish, extended tool life, and seamless integration on high-precision automotive brake resurfacing systems.
Engineered specifically for FMC and John Bean brake lathe systems, the CB90488 turning insert delivers uncompromising performance in high-precision automotive rotor resurfacing. Manufactured from premium tungsten cemented carbide (GS06/YG6X grade) with a certified hardness of 92.1 HRA and density of 14.74–14.8 g/cm³, this uncoated insert eliminates thermal barrier interference while maximizing edge retention, dimensional stability, and chip control under continuous heavy-duty cutting.
Designed for direct drop-in compatibility with standard FMC/John Bean tool holders, it supports both maintenance-driven refurbishment and high-volume remanufacturing operations — offering B2B customers a reliable, repeatable, and cost-optimized alternative to proprietary OEM consumables.
92.1 HRA hardness ensures exceptional wear resistance and thermal stability — no coating required. Eliminates delamination risk, reduces heat buildup, and maintains sharp geometry through prolonged engagement on cast iron and composite rotors.
Precision-ground geometry and mounting interface match original equipment specifications for TURNING CENTER and CNC Lathe platforms. Ensures zero setup recalibration and full interchangeability with existing tooling systems.
Standard model CB90488 ships globally with MOQ as low as 10 pcs. Full customization available — including custom grades (e.g., GS06/YG6X), edge prep, packaging configuration, and branding — backed by Hunan-based production and QC traceability.

We support full OEM/ODM collaboration — from material grade optimization and geometry refinement to custom packaging, labeling, and logistics solutions. All inserts undergo rigorous dimensional verification, hardness sampling, and microstructure inspection prior to shipment. Traceable batch documentation and QC reports available upon request.
While optimized for FMC and John Bean brake lathe geometries and holder interfaces, physical compatibility with other CNC turning centers depends on insert seat dimensions and clamping mechanism. We recommend verifying holder specs (e.g., ISO CNMG 120408, WNMG 080408) and requesting a technical fitment review prior to integration.
Standard CB90488 orders ship within 5–7 business days. Custom requests (grade, geometry, packaging) require 12–18 days for prototyping and validation. Rush options are available — contact engineering support for feasibility assessment.
Yes. Our technical team offers free cutting parameter recommendations, troubleshooting for chatter or premature wear, and on-site or virtual tooling audits for high-volume clients. Support is included with all orders above USD $5,000.
