Tungaloy WB WP WC Series 80° Trigon Positive Inserts | Precision Turning

Tungaloy WB / WP / WC 80° Trigon Positive Inserts

High-Precision Small Diameter Boring | Low Cutting Force | Premium Surface Finish

Which trigon positive insert is ideal for precision internal boring with minimal vibration?

The Tungaloy WB, WP, and WC Series represent the pinnacle of small-part precision. Featuring an 80° trigon shape with a positive relief angle, these inserts provide more clearance than traditional diamond shapes while offering superior edge strength compared to triangular geometries. Tungaloy utilizes PremiumTec coating technology, such as the universal AH725 PVD for high-toughness requirements and NS530 Cermet for mirror-like finishing in steel. The unique -JS and -PF chipbreakers are specifically engineered to prevent chip bird-nesting in blind holes, ensuring stable, unattended machining on CNC Swiss-type and precision lathes.

Minimal Cutting Resistance

The positive rake and optimized relief angles prevent part deflection on thin-walled workpieces and long-reach boring bars.

Ground Edge Precision

Available in G-class ground peripheries (WBGT/WCGW) for high-accuracy finishing with tolerances within microns.

Exceptional Chip Breaking

Proprietary Tungaloy chipbreakers ensure short, manageable chips even at very low feed rates in light finishing cycles.

User Testimonials

⭐⭐⭐⭐⭐ "Perfect for Swiss Lathes" - Thomas L., Germany
"The WBGT 06 series with JS chipbreaker is the only insert that solved our bird-nesting issues on our Star machine. High precision."

⭐⭐⭐⭐⭐ "Mirror Finish on 4140" - Robert K., USA
"Used the NS530 grade for finishing passes. Surface finish is impeccable. Beyond CNC was quick to answer my tech questions."

⭐⭐⭐⭐⭐ "Tough Boring" - Marco V., Italy
"WPMT in AH725 grade works great for boring stainless steel. Edge lasts way longer than my previous supplier."

Frequently Asked Questions

Q: What is the difference between WB, WP, and WC?

A: These signify the relief angle: WB has 5°, WC has 7°, and WP has 11°. Choose the angle based on the clearance needed for your specific boring operation.

Q: Can I use these for Aluminum?

A: Yes. We recommend the ground **WCGW** series in **KS05F** grade for a sharp edge that prevents sticking in soft materials.

Industrial Tip: Chip Evacuation

For internal boring with **WB/WP/WC** inserts, ensure your coolant is directed precisely at the cutting edge. In small diameters, chip accumulation is the #1 cause of insert breakage. **BEYOND CNC** - Machining Excellence.
