PCD T-slot milling cutter

Engineered specifically for your exact slotting dimensions. Our custom PCD T-slot milling cutters provide the ultimate solution for machining precise T-slots, undercuts, and fluid channels in non-ferrous metals and abrasive composites. Featuring reinforced neck designs and optimized geometries, we solve the industry’s biggest challenges: poor chip evacuation and tool breakage.

Ideal Machining Operations

  • Precision T-Slot Milling Machining exact T-shaped slots for machine tables, automotive fixtures, and structural aerospace components.

  • Undercutting & O-Ring Grooves Creating highly accurate internal undercut grooves, fluid channels, and O-ring seats where standard end mills cannot reach.

  • Complex Slotting in Abrasive Materials Delivering burr-free, mirror-like slot finishes in aluminum alloys, copper, CFRP, and engineering plastics.

Advantages of Sundi T-Slot Cutters

100% Custom Engineered to Your Drawing

T-slots are never one-size-fits-all. We manufacture strictly to your exact required cutting diameter, cutting width (thickness), and neck clearance, ensuring a perfect fit for your specific groove.

Optimized Chip Evacuation

Carefully engineered chip gullets and rake angles ensure rapid chip removal, drastically reducing heat buildup and preventing catastrophic tool failure.

Staggered Flute Design

Optional staggered PCD teeth significantly reduce cutting forces and vibration, breaking chips effectively to prevent jamming within tight enclosed slots.

Reinforced Neck Rigidity

We utilize premium high-strength tungsten carbide for the tool body, specifically reinforcing the neck area to prevent deflection and snapping during heavy slotting operations.
