WCMT06T308 AH120 — indexable insert for drilling, Tungaloy

The WCMT06T308 AH120 is an indexable insert for drilling applications, engineered for exchangeable-insert drill systems where sharp cutting edges and process security are required.

• PVD-coated carbide for wear resistance
• Trigon form for secure seating and three cutting edges
• Single-sided chipbreaker for predictable chips
• Cylindrical hole with 40°–60° countersink for reliable clamping

High-performance coating and grade for consistent cutting

The insert is manufactured from cemented carbide and finished in a PVD-coated carbide grade (AH120) that combines wear resistance with fracture toughness. This composition supports stable chip formation and preserves a sharp cutting edge, reducing interruptions caused by edge chipping. The result is a measurable improvement in cycle consistency and longer intervals between insert changes, which supports a smoother production flow in repetitive drilling operations.

Secure seat geometry and practical mounting details

Designed as a trigon plate with a 0.8 mm corner radius, the geometry provides three effective cutting edges per indexable unit and a firm seating position in compatible drill bodies. The insert is supplied with hole, featuring a cylindrical hole with a one-sided countersink (40°–60°) and a 7° clearance that together enable correct axial positioning and secure clamping. A plate thickness of 3.97 mm and an 80° included angle must be checked against the drill holder and intended drill diameter to ensure correct fit and performance.

Operational advantages and application fit

Optimised for drilling, the indexable insert supports reliable performance across standard drilling tasks where a sharp edge and process security are necessary. The single-sided chipbreaker simplifies chip control for many materials and reduces the need for frequent adjustments. Specifying this insert helps to lower machining downtime and contributes to consistent part quality; pairing the insert with an appropriately matched drill body, clamping screw and key ensures the full benefits are realised on the shop floor.

FAQ

What materials is this insert suitable for?
The WCMT06T308 AH120 insert is specified for general drilling applications and, thanks to the AH120 PVD-coated carbide, is suitable where wear resistance and edge stability are required; material-specific recommendations should be checked against machining parameters.

How does the trigon form benefit clamping and cutting?
The trigon geometry provides three indexable cutting edges and a stable seat in compatible drill bodies, improving repeatability and enabling multiple reindexes before replacement.

What clamping features must the drill body provide?
A drill body must match the plate size (06) and accept a cylindrical hole with one-sided countersink (40°–60°) and provide secure axial support to exploit the insert’s 7° clearance and seating geometry.

Is the insert suitable for high-speed drilling?
The PVD coating and the AH120 grade increase resistance to wear and thermal loads; however, recommended cutting speeds depend on workpiece material and machine capability and should be validated in process trials.
