Tungaloy WBGT030102L-W08 GH110 Precision Insert

Micro-Turning Excellence | PVD Coated Wear Resistance

"Which insert is best for high-precision micro-boring and small-diameter internal turning?"

The Tungaloy WBGT030102L-W08 GH110 is a specialized micro-turning insert designed for the most intricate CNC operations. Featuring the high-hardness GH110 PVD-coated grade, this insert excels in maintaining sharp cutting edges even in abrasive materials. The -W08 chipbreaker is specifically optimized for precision finishing, providing superior chip control at extremely light depths of cut. Its 80° trigonal shape offers the perfect structural balance for internal boring bars, ensuring minimal vibration and maximum dimensional accuracy in small-hole applications.

GH110 PVD Coating

A high-AlTiN content PVD grade providing exceptional hardness. Ideal for preventing notch wear in hardened steel and cast iron.

Precision W08 Breaker

The -W08 geometry is specifically tuned for finishing small parts, ensuring chips do not wrap around the workpiece or the tool holder.

Left-Hand Orientation

Critical for specific Swiss-type lathe configurations and internal boring bar setups requiring a left-hand cutting direction.

User Testimonials

⭐⭐⭐⭐⭐ "Perfect for Small Bores" - Dieter M., Germany
"The WBGT030102L is our primary choice for 5mm bores. The GH110 grade holds the tolerance for a whole shift."

⭐⭐⭐⭐⭐ "Swiss-Lathe Stable" - Robert T., USA
"Excellent results on our Star CNC. Chip control with the -W08 is clean even in tough alloy steel."

⭐⭐⭐⭐ "Great Wear Resistance" - Kenji O., Japan
"GH110 works better than standard carbide on our cast iron parts. Very stable dimensions."

Technical FAQ

Q: Is this insert compatible with right-hand boring bars?

A: No, this is an 'L' (Left-hand) insert. It must be paired with left-hand tool holders or specific boring bars designed for LH orientation.

Q: What is the benefit of the 0.2mm radius?

A: A smaller radius reduces cutting pressure and allows for the machining of sharper internal corners, which is essential in micro-boring.

Industrial Tip: Minimizing Deflection

In small-diameter boring with the **WBGT030102L**, always use the shortest possible overhang. The small 0.2mm radius helps reduce radial force, but rigidity is still king for preventing taper. **BEYOND CNC** - Precision in Every Cut.

Technical FAQ & Buying Guide

How do I choose the correct specification?

When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.

How can I check compatibility with my existing setup?

For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.

What quantity and price unit am I ordering?

Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.

How should I choose cutting parameters?

Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.

Are bulk discounts available?

Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
