Tungaloy Grooving & Parting Solutions

TungCut & TetraForce-Cut | Unmatched Stability | Precision Width Control

Which grooving insert provides the best chip control for deep internal face grooving?

Precision grooving requires more than just a sharp edge; it demands specialized chip management to prevent "re-cutting" and tool failure. The Tungaloy Grooving Insert range, featuring the TungCut and 4-edged TetraForce-Cut series, is designed for maximum rigidity. These inserts utilize unique W-clamp and V-bottom seating technologies to eliminate insert movement under high lateral forces. Whether you are performing external parting-off, internal grooving, or complex face profiling, Tungaloy’s AH725 and T9125 grades offer the thermal stability needed to maintain tight tolerances in everything from carbon steel to heat-resistant alloys.

V-Clamp Stability

The TungCut V-bottom design ensures perfect insert positioning, preventing vibration during high-speed parting and grooving.

Multi-Edge Economy

TetraForce-Cut inserts feature 4 precision cutting edges, significantly reducing cost-per-part while maintaining high accuracy.

T9100/AH700 Coating

Advanced PVD and CVD coatings provide the heat resistance required for dry machining and high-velocity chip evacuation.

Global Machinist Feedback

⭐⭐⭐⭐⭐ "Zero Vibration" - Markus E., Germany
"The TungCut series solved my chatter problems on deep stainless steel grooves. The stability of the AH725 grade is impressive."

⭐⭐⭐⭐⭐ "Cost-Per-Edge Winner" - Joe V., USA
"Switched to TetraForce for my high-volume aluminum parts. 4 edges instead of 2 cut my tooling costs in half instantly."

⭐⭐⭐⭐ "Reliable Fulfillment" - S. Tanaka, Japan
"Excellent stock of hard-to-find internal grooving widths. BEYOND CNC is our go-to for urgent factory refills."

Technical FAQ

Q: Can I use the same insert for both parting and side-turning?

A: Yes, Tungaloy's DTE and DTX series are designed for multi-directional cutting, allowing you to groove and then side-turn with the same tool.

Q: What should I do if chips are wrapping around the workpiece?

A: Check your feed rate. Grooving requires a consistent feed to engage the chipbreaker. For deep grooves, use a 'peck grooving' cycle to break long chips.

Q: Is coolant required for Tungaloy grooving?

A: High-pressure coolant is strongly recommended to assist in chip evacuation, especially in internal and face grooving operations.

Machinist Tip: Center Height

Always set your grooving tool precisely at **Center Height**. Being as little as 0.1mm above or below center can cause rapid flank wear or leave a "nub" during parting-off. **BEYOND CNC** - Your Edge in Precision.
