WCGT040202-X5 WK1 drilling/boring indexable insert by Walter Tools — Trigon 80°, X5 chipbreaker

The WCGT040202-X5 WK1 is an uncoated cemented carbide indexable insert designed for drilling and boring applications where stable cut entry and controlled chip flow are required

• Trigon 80° geometry for stable tool engagement
• X5 chipbreaker for controlled chip formation
• 7° clearance angle for reduced friction
• Uncoated cemented carbide - WK1 grade

Stable engagement and reliable chip control for boremaking

The Trigon 80° configuration delivers a larger engagement area compared with sharper-point inserts, which increases axial stability and reduces vibration during entry. Combined with the X5 chipbreaker, this geometry actively fragments and directs chips away from the cutting zone, enhancing process reliability. The described features support longer uninterrupted cycles and more consistent hole quality, while the modest 0.2 mm corner radius helps to blunt the cutting edge slightly, reducing the risk of corner chipping on interrupted cuts. Technical terms: a chipbreaker is a shaped land on the insert face that alters chip flow; the corner radius distributes cutting loads and improves edge strength.

Grade and material considerations for predictable tool life

The cutting grade WK1 is specified as an uncoated cemented carbide. Uncoated carbide grades are often chosen for their predictable wear behaviour and for applications where coating adhesion is critical or where secondary coatings would alter cutting geometry. The choice of grade makes this insert suitable for a range of conventional machining tasks; however, material suitability should be verified against the product matrix for specific workpiece materials and machining parameters. The combination of geometry and grade aims to balance wear resistance with fracture toughness to maintain consistent edge condition over repeated cycles.

Practical handling, mounting and process recommendations

The insert’s 7° clearance angle reduces flank contact and lowers frictional heat at the tool–workpiece interface, which can extend tool life under moderate feeds and speeds. The Trigon 80° form facilitates straightforward seating in compatible drill or boring heads; correct torque and secure clamping are essential to fully benefit from the insert’s stability. For optimised results, select feeds and spindle speeds according to the chosen workpiece material and refer to the tooling system’s recommended parameters. For complex materials or high-demand cycles, consult the tooling matrix to confirm whether prehardened or exotic alloys are appropriate for this uncoated grade.

FAQ

What is the primary application for this insert? The WCGT040202-X5 WK1 indexable insert from Walter Tools is designed for drilling and boring operations where stable entry and controlled chip evacuation are priorities; it suits applications that benefit from Trigon 80° geometry and an active chipbreaker.

Which materials is the WK1 grade suitable for? The WK1 grade is an uncoated cemented carbide; material suitability depends on the machining matrix—consult the product matrix to confirm compatibility with specific materials and hardness levels.

How does the X5 chipbreaker affect machining? The X5 chipbreaker promotes manageable chip formation and evacuation, reducing the likelihood of long, stringy chips and improving process stability during holemaking.

Are there special mounting requirements for the Trigon 80° insert? The Trigon 80° shape requires a compatible seat in the drill or boring head and correct clamping torque to ensure stability; proper toolholder maintenance and secure fastening are recommended to exploit the insert’s geometry.

Is the WCGT040202-X5 WK1 coated? No, the specified grade WK1 is an uncoated cemented carbide; coating information is not listed and should be verified if a coated variant is required
