Working Principle

The internal coolant system delivers coolant directly to the cutting edge, reducing heat and improving lubrication during high-speed drilling. This prevents built-up edges and extends tool life. The straight flute geometry ensures smooth, controlled chip evacuation, critical when drilling aluminium and copper to prevent chip jamming. The step drill design allows multiple hole diameters to be machined in a single pass, increasing efficiency while maintaining concentricity and precision.

Advantages

✓ AMG precision grinding ensures sharp edges for clean cutting and accurate hole dimensions

✓ Internal coolant system enhances heat dissipation and chip removal

✓ Straight flute geometry prevents chip jams and ensures excellent chip evacuation

✓ Step drill design allows for efficient multi-diameter drilling in one operation

✓ Ultra-fine carbide material provides long tool life and stable performance

✓ Produces burr-free holes, reducing the need for secondary processing

✓ OEM customization available, including logo engraving and special coatings
