90-Degree Countersink Bit
This 90-degree countersink bit is designed for deburring, chamfering, and countersinking holes in materials like steel, aluminum, plastic, and wood. It features a precision-ground cutting edge for clean performance and is suitable for drill presses, lathes, and CNC machines.




Technical Specifications
Overview
High-Performance 90-Degree Countersink
This precision-engineered countersink bit is designed for universal application across steel, aluminum, plastic, and wood. Featuring three distinct convex cutting edges and extremely unequal spacing, it ensures a low-vibration, chatter-free process for clean hole finishing. The advanced geometry significantly reduces axial and radial forces, making it an efficient choice for manual and CNC machining operations.
