1008 Secondary/Backup Cutter

The 1008 secondary cutter is primarily used for gauge protection and backup support on drill bits. Despite its smaller size, it utilizes the same premium diamond material as primary cutters to ensure accurate and constant borehole sizing. It shares the load with primary teeth, preventing irregular bit wear. Under high-speed rotation, it effectively protects the bit matrix from rock erosion. Its excellent cost-performance ratio makes it a core component in gauge and anti-balling bit designs.
