Y.T. Indexable T-Slot Cutter (3T) - Metric - 80 mm Saw Diameter for LNGT Inserts - Insert Width 3 to 4mm (3T2580-3.0)

The Y.T. Indexable 3T-T Slot Cutter (80 mm) is a metric precision tool built for CNC milling operations that require consistent T-slot geometry. Designed specifically for LNGT inserts with 3–4 mm widths, it pairs durable carbide indexing with an 80 mm saw diameter to maintain tight slot tolerances across repeated production runs.

• Saw Diameter: 80 mm metric profile engineered for standard CNC milling arbors and spindle mountings.
• Insert Compatibility: Configured for LNGT indexable inserts measuring 3–4 mm wide (covers model 3T2550-4.0).
• Tapered-Polygon Mount: Polygon-based body locking ensures exact center placement, eliminating positional play during heavy engagement.
• Modular Shank Platform: Fully compatible with UFO-style carbide blades; a single shank body accepts up to 400 insert replacements across various thicknesses and grades.
• System Coverage: The six-shank family addresses the entire CAPTO interface range, enabling nine cutter permutations and more than 1,400 valid insert setups.
• Advanced Geometry: Refined cutting angles paired with reinforced flute channels provide superior chip evacuation and reduce cutting resistance.

Transitioning from solid HSS or brazed T-slot blanks saves significant machine hours by allowing operators to swap worn edges instead of changing out the entire cutter body. The tapered-polygon alignment drastically lowers radial runout, preserving dimensional accuracy and extending overall tool endurance. Quick indexable changes cut setup downtime, while the broad insert ecosystem lets shops match any alloy or cast iron to the correct carbide formulation. Machinists achieve steadier feed rates, cleaner finished surfaces, and recurring cost savings through a flexible, toolholder-driven workflow that delivers processing speeds up to three times faster than traditional welded alternatives.
