Y.T. Indexable T-Slot Cutter (3T) - Metric - 40 mm Saw Diameter for LNGT Inserts - Insert Width 8mm (3T1640-8.0)

The Y.T. Indexable T-Slot Cutter (3T1640-3.0) is a precision metric tool built for CNC milling operations that require consistent T-slot machining. Engineered for a 40 mm saw diameter and an 8 mm insert width, it delivers stable cutting performance while supporting rapid LNGT-compatible insert replacements to maintain uninterrupted production cycles.

• Saw Diameter & Insert Profile: 40 mm diameter precisely matched to an 8 mm wide LNGT-style insert seat for secure positioning.
• Tapered-Polygon Connection: Provides exact center alignment to reduce vibration and runout during deep or heavy slotting passes.
• Modular Indexable Design: Allows individual insert replacement without removing or discarding the complete cutter holder.
• CAPTO & Shank Compatibility: Integrates with YIH TROUN T-slot shanks and spans the full CAPTO range, offering nine cutter configurations and backing up to 1,400 UFO-type inserts across varied diameters, thicknesses, and grades.
• Optimized Geometry: Refined cutting edges and clearance angles positioned to maximize material removal rates and ensure steady chip flow.

This indexable cutter outperforms traditional solid HSS and welded T-slot tools by enabling fast, tool-free insert exchanges that drastically lower consumable costs and machine idle time. The tapered-polygon mount combined with optimized chip clearance achieves up to 300% higher machining efficiency, reducing cycle times while preserving dimensional repeatability on precision components. Full CAPTO shank integration means your workshop can rely on a single scalable platform that accommodates nine distinct cutter layouts and thousands of insert combinations, eliminating the need to stock multiple specialized cutters for changing part geometries and material specs.
