OKAZAKI Reamer Model MR0660 Size 6.6 mm
The OKAZAKI MR0660 is a Japanese-standard straight flute machine reamer made of high-speed steel (HSS). It is engineered specifically for fine reaming (finishing) 6.6 mm holes, focusing on high precision to achieve exact engineering tolerances while providing an exceptionally smooth internal surface finish.
Feature
High-Speed Steel (HSS): Manufactured from premium-grade high-speed steel, offering high rigidity, wear resistance, and long-lasting edge retention.
Straight Flute Geometry: Straight cutting flutes enhance tool rigidity during operation and minimize chatter, resulting in perfectly round holes.
Japanese Quality Standards: Manufactured under Japanese Industrial Standards (JIS), ensuring 6.6 mm diameter accuracy and consistent quality across every piece.
Exceptional Surface Finish: Refines pre-drilled hole surfaces into smooth, glossy finishes, reducing friction when assembling parts or inserting 6.6 mm pins.
Standard Straight Shank: Standard straight round shank for secure and precise clamping in collet chucks or standard machine drill chucks
Application
Used for precision reaming to adjust pre-drilled holes to a specific 6.6 mm size according to engineering drawings
Suitable for mounting on industrial machinery such as CNC machines, milling machines, lathes, or precision drill presses
Compatible with a wide variety of materials, such as mild steel, cast iron, aluminum, copper, and engineering plastics.
Recommendation: For maximum performance and the finest surface finish, use with coolant or cutting oil during operation.
