Precision CNC Cutting Performance

SPMG series U Drill inserts deliver exceptional durability with premium carbide substrate and advanced TiAlN coating for heat resistance up to 900°C. Ultra-fine grain structure ensures 30% longer tool life versus standard inserts.

Multi-Tasking Machining Mastery

Engineered for high-speed drilling in stainless steel, cast iron, and hardened alloys. Features 7° positive rake geometry for reduced cutting forces in deep-hole applications (3xD to 5xD depth).

Global Industrial Standard Compliance

Interchangeable with ISO SPMG070304/SPMG09T308 specifications. Precision-ground cutting edges maintain ±0.002mm tolerance for aerospace-grade surface finishes (Ra 0.8μm achievable).

Strategic Cost Efficiency

Direct-from-factory pricing with bulk order discounts. MOQ-friendly for machine shops requiring 50+ inserts. Compatible with leading CNC brands including Sandvik Coromant and Kennametal tool holders.

Application-Specific Engineering

Ideal for automotive crankshaft drilling, mold base machining, and oil/gas valve production. Chipbreaker geometry prevents workpiece adhesion during interrupted cuts.
