OSG's A Brand XPF forms threads by deformation of the work material and does not generate cutting chips resolving tapping troubles that are caused by unstable chip evacuation. The A-XPF enables the reduction of tool change time caused by cutting chip troubles and machine downtime required for removing accumulated cutting chips. Enabling stable and uninterrupted machining, the A-XPF can reduce power consumption, which minimized environmental impact.
Features & Benefits:
- Special chamfer specification: Achieves stable machining with reduced thrust
- Special thread configuration: Improved cutting edge and thread rigidity
- New VI Coating formulated for high-performance taps: Is suitable for high-loading machining with high-hardness, oxidation resistance and excellent lubricity
