TaeguTec WBMT060102L-C CT3000 Inserts
Precision Small-Bore Finishing | Positive 80° Trigon Cermet | CT3000 Grade | Box of 10 Pcs
"Which positive cermet insert is best for high-precision small-bore finishing and fine turning in steel?"
The TaeguTec WBMT060102L-C CT3000 is a high-precision, positive 7° clearance 80° trigon turning insert engineered specifically for fine internal boring, back-turning, and close-tolerance finishing on CNC lathes. Manufactured from TaeguTec's premier CT3000 uncoated TiCN-based cermet grade, this insert delivers exceptional wear resistance and eliminates Built-Up Edge (BUE) when machining carbon steels, alloy steels, and ductile cast irons. Featuring a crisp 0.2mm corner radius, left-hand cutting geometry (L), and the specialized C-type finishing chipbreaker, it generates ultra-low radial cutting forces that prevent chatter and tool deflection inside slender bores. While heavy roughing applications rely on TaeguTec negative turning inserts, this positive WBMT geometry excels in delicate finishing passes requiring mirror-like Ra surface finishes.
Core Engineering Advantages
CT3000 Mirror-Finish Cermet
Uncoated TiCN cermet resists chemical affinity with iron, preventing material welding and eliminating secondary grinding steps.
C-Style Precision Chipbreaker
Sharp positive rake geometry curls delicate finishing chips cleanly at shallow depths of cut without scratching bore walls.
Low-Force 7° Positive Clearance
0.2mm nose radius and positive relief angle minimize radial pressure, preventing vibration in high-overhang boring bars.
ISO Code Specification Breakdown
Technical Specifications & Dimensional Comparison
| Parameter | Metric (Standard) | Imperial Equivalent |
|---|---|---|
| ISO / ANSI Designation | WBMT 060102L-C | WBMT 2(1.5)0.5L-C |
| Inscribed Circle (IC) | 3.97 mm | 0.156" (5/32") |
| Thickness (S) | 1.59 mm | 0.0625" (1/16") |
| Corner Radius (RE) | 0.20 mm | 0.008" |
| Grade & Substrate | CT3000 (Uncoated TiCN Cermet) | High-Speed Finishing Cermet |
Recommended Cutting Parameters
*Cermet performs best at elevated surface speeds (Vc) with shallow depths of cut. Run completely dry or with continuous flood coolant to prevent thermal shock.
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (Ap) |
|---|---|---|---|
| Carbon Steel (1045 / S45C) | 180 - 380 m/min | 0.04 - 0.16 mm/rev | 0.10 - 1.00 mm |
| Alloy Steel (4140 / SCM440) | 150 - 320 m/min | 0.04 - 0.14 mm/rev | 0.10 - 0.80 mm |
| Ductile & Gray Cast Iron | 160 - 350 m/min | 0.05 - 0.18 mm/rev | 0.15 - 1.00 mm |
Compatible Tooling & Boring Bar Guide
Pair these inserts with precision small-shank screw-clamp boring bars (such as SWLCR/L or SWUBR/L series) designed for WBMT 0601 pockets. Need help matching holder sizes and insert geometries? Read our engineering guide on how to choose the right boring bar and insert.
For larger internal bore roughing and medium turning setups, explore our heavy-duty negative trigon holders: S16Q-MWLNR06 Boring Bar, S18Q-MWLNR08 Boring Bar, and S25S-MWLNR08 CNC Boring Bar Holder.
Industrial Applications
- Small-Diameter Internal Boring: Achieving mirror-like Ra surface finishes inside hydraulic valve bodies, bushings, and precision sleeves.
- Swiss-Type & Gang-Tool CNC Turning: Low-force finishing and facing on slender shafts without workpiece deflection.
- Left-Hand Profiling & Back-Turning: Ideal for specialized turret configurations requiring left-hand feed direction.
System Compatibility & Related Tooling
The WBMT 060102L-C fits standard ISO-compliant screw-clamp boring bars and external turning holders built for 0601-size positive 80° trigon pockets. If your production line also runs negative double-sided inserts for higher stock removal, browse our full catalogs of TaeguTec WNMG inserts, TaeguTec CNMG inserts, and TaeguTec TNMG inserts, or compare cross-brand trigon options across Korloy WNMG and ZCC-CT WNMG lines.
TaeguTec Grade Selection Matrix
Choosing the right TaeguTec grade for precision turning:
- CT3000 (Featured - Uncoated Cermet): Unmatched surface finish quality and wear resistance in high-speed continuous finishing of carbon and alloy steels.
- PV3010 (PVD Coated Cermet): Pairs a cermet substrate with a PVD coating for higher thermal shock resistance in light interrupted cuts.
- TT9080 / TT9030 (PVD Coated Carbide): Recommended when machining sticky austenitic stainless steels (304/316) or when higher edge toughness is required.

Frequently Asked Questions
Q: What does the "L" in WBMT060102L-C indicate?
A: "L" denotes a Left-Hand cutting insert. Because positive WBMT inserts are single-sided with an angled clearance face, a left-hand insert must be paired with a corresponding left-hand boring bar or turning holder.
Q: Why use a 0.2mm corner radius for small-bore turning?
A: A small 0.2mm (0.008") radius minimizes radial cutting pressure, preventing long, slender boring bars from vibrating or deflecting away from the bore wall—ensuring straight, accurate inner diameters.
Q: How many inserts come in one package?
A: Each factory-sealed box contains 10 original TaeguTec WBMT060102L-C CT3000 inserts (3 indexable corners per insert, 30 edges per box).

Technical FAQ & Buying Guide
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.
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.
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.
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.
