SPGT U Drill Insert

1. Technical performance advantages

U-shaped groove patented design

Enhanced chip removal: The unique U-shaped spiral groove structure (compared with traditional straight grooves) significantly improves chip removal efficiency and reduces the risk of clogging, especially suitable for deep hole processing (such as 5D depth or more).

Reduced heat accumulation: The optimized groove shape reduces friction in the cutting area and extends tool life.

Integrated internal cooling channel

High-pressure cooling directly to the tip: Supports 3D internal cooling (Coolant Through), the coolant acts directly on the cutting edge, reduces thermal deformation of the workpiece, and improves the finish of the hole wall (Ra≤1.6μm).

Compatible with a variety of cooling media: Suitable for oil cooling, air cooling or emulsion, suitable for different materials (such as stainless steel, titanium alloy).

High rigidity material

Ultra-fine grain carbide substrate: Wear resistance is increased by more than 30% (compared with ordinary alloy drills), with TiAlN/TiSiN coating, high temperature resistance up to 1200℃.

2. Processing efficiency advantage

One tool for multiple uses

No need for pre-drilling or center drilling: directly achieve high-precision hole processing (IT8-IT9 level), save tool change time, and improve CNC machine tool utilization.

High-speed cutting ability

Recommended line speed 80-150m/min: 20% higher feed rate than traditional drill bits in cast iron/steel processing, and 15% shorter single hole processing cycle.

Stability optimization

Double-edge design: Enhance radial rigidity, suppress vibration, hole roundness error ≤0.02mm (suitable for thin-walled parts).
