BIG TCGT110204EL PVD Coated Carbide Turning Insert with EL Chipbreaker and R0.4 Corner Radius for Precision CNC Turning Carbide inserts

The TCGT110204EL is premium coated fine-grain carbide precision finishing insert dedicated for small part inner bore and outer diameter finish turning on CNC lathes and Swiss automatic lathes. Featuring 60° triangular positive rake TCGT geometry, EL sharp-edge fine-finish chipbreaker structure and premium wear-resistant carbide substrate, the insert delivers low cutting resistance and outstanding anti-adhesion performance to keep stable cutting during continuous high-precision finish machining of steel and non-ferrous materials.

Optimized EL edge and chip groove design achieves short fragmented chips and unobstructed chip removal, ensuring ultra-smooth workpiece surface and tight dimensional tolerance for miniature component mass production.

• Fine-grain tungsten carbide base with low-friction PVD coating balances sharp cutting edge and moderate wear resistance, suitable for high-speed finish turning of carbon steel, stainless steel, copper and aluminum alloy.
• Exclusive EL sharp honed edge reduces cutting load, effectively suppresses built-up edge during precision finishing.
• Standard TCGT1102 insert specification with positive large clearance angle, small cutting resistance, matched perfectly with corresponding TCGT series tool holders.
• Ultra-precision ground cutting edge realizes high-quality finished surface, greatly omitting follow-up polishing procedures.
• Reasonable edge strengthening design avoids tiny edge chipping in long-cycle small-bore continuous machining and extends insert service life.

• Carbon steel
• Austenitic stainless steel
• Aluminum alloy
• Copper & brass
• Low hardness engineering plastic

• Miniature part precision outer diameter finishing
• Small-diameter deep inner hole fine boring
• Swiss automatic lathe precision component processing
• Light interrupted thin-wall part finish turning
• High-surface-quality small batch turning

Combining low-resistance positive rake structure and professional EL finishing chipbreaker design, TCGT110204EL maintains stable precision cutting for small-size precision parts. Excellent anti-adhesion and fine surface machining ability improves product yield and shortens processing cycle, being cost-effective dedicated finishing insert for precision workshop and Swiss lathe production.
