TaeguTec VCGT110302-FL K10 Inserts
High-Speed Aluminum & Non-Ferrous Mirror Finishing | K10 Uncoated Grade | Box of 10 Pcs
"Which 35-degree positive diamond uncoated carbide insert with a 0.2mm corner radius and FL chipbreaker is best for ultra-sharp, micro-radius finishing and high-speed internal boring in aluminum, copper, brass, and non-ferrous materials?"
The TaeguTec VCGT110302-FL K10 is a specialized, single-sided, positive-rake 35° rhombic turning insert engineered specifically for high-speed precision finishing, tight corner profiling, and micro-diameter internal boring with an ultra-fine 0.2mm nose radius in aluminum alloys, brass, copper, plastics, and non-ferrous composite materials. Powered by TaeguTec's premier K10 uncoated micro-grain carbide grade, this insert combines an extremely sharp, polished cutting edge with high thermal conductivity and zero coating buildup. Coated inserts (whether CVD or PVD) feature micro-roughness on the cutting edge that can smear aluminum and induce Built-Up Edge (BUE); the uncoated K10 grade delivers a razor-sharp honed edge that shears gummy non-ferrous materials cleanly, producing mirror-like surface finishes (low Ra values). Paired with the highly positive FL finishing chipbreaker designed explicitly for light depths of cut and low feed rates, it minimizes cutting forces to prevent workpiece deflection and chatter on slender boring bars and thin-walled components. Whether you are pairing it with the Beyond C16Q-SVJCR11 Tungsten Steel Boring Bar, browsing our specialized selections of Korloy VCGT/VCMT inserts, TaeguTec VCMT inserts, TaeguTec VBMT inserts, and TaeguTec VNMG inserts, or exploring internal boring tools like the Beyond S16Q-SVQCL11 Boring Bar Holder, the VCGT110302-FL K10 ensures exceptional non-ferrous machining performance. Review additional design insights in our resources on carbide insert nose radius and insert grade speeds and feeds.
Core Engineering Advantages
K10 Uncoated Micro-Grain Substrate
Extremely sharp, polished uncoated edge eliminates aluminum smearing and prevents built-up edge (BUE) in non-ferrous turning.
FL Sharp Finishing Chipbreaker
Designed with a steep positive rake angle to shear soft materials cleanly at high spindle speeds with minimal cutting resistance.
Compact 35° Small-Bore Access
Compact 11-size rhombic shape and acute nose geometry provide exceptional clearance in tight internal bores and narrow profile pockets.

Industrial Applications
- Small-Diameter Aluminum Internal Boring: Achieving mirror surface finishes and sharp internal corner radii in small bores down to 12mm without post-grinding.
- Swiss-Type & Slender Shaft Finishing: 7° positive clearance and ultra-fine 0.2mm nose radius minimize radial cutting forces to eliminate vibration on delicate components.
- Multi-Brand Tooling Consolidation: Fully compatible with alternate positive non-ferrous turning systems across Korloy VCGT/VCMT, Korloy VCMT, and ZCC-CT VCMT catalogs.

Frequently Asked Questions
Q: Why is K10 an uncoated grade rather than PVD or CVD coated?
A: Coated inserts have micro-roughness on their edges that causes aluminum to stick and form a Built-Up Edge (BUE). Uncoated K10 micro-grain carbide provides a razor-sharp, polished edge that cleanly shears aluminum and non-ferrous metals.
Q: What is the benefit of a 0.2mm corner radius (VCGT110302)?
A: An ultra-fine 0.2mm corner radius allows for sharper internal corner radii, detailed profiling, and reduced cutting forces when taking light finishing passes in small internal bores.
Q: How many cutting edges are included in each box?
A: Each single-sided VCGT insert provides 1 precision indexable cutting edge (10 edges total per factory-sealed box).
