Precision Grinding Coolant Through Drill Bits Straight Flute Drill For Deep Hole Processing

The AMG solid carbide coolant-through straight flute drill is specifically designed for deep and blind hole machining in machinery structural parts. Manufactured using high-quality ultra-fine grain solid carbide (HM) with precision grinding, it offers:

• High hardness and excellent wear resistance
• Superior anti-chipping performance for stability
• High hole accuracy during processing
• Internal coolant channel design for direct high-pressure coolant delivery
• Rapid heat dissipation and reduced cutting temperatures
• Improved chip evacuation and extended tool life

Ideal for deep and blind hole machining in:

• Shafts and jigs
• Hydraulic cylinder holes
• Mold cooling channels

Suitable for high-precision, high-surface-finish deep hole drilling in:

• Carbon steel and alloy steel
• Stainless steel
• Aluminum alloys and copper alloys

• Material: Ultra-fine grain solid carbide (HM)
• Cooling: Coolant-Through
• Flute Type: Straight Flute
• Diameter Range: Φ3mm - Φ12mm (customizable)
• Cutting Length: 6D / 10D / 15D / 20D (customizable)
• Coating: TiAlN / DLC / Uncoated options available

When selecting an internally cooled straight flute drill, consider:

• Drilling depth: For holes exceeding 6 times the diameter, choose long-edge designs (10D, 15D, 20D) for smooth chip evacuation
• Processing materials:
  • TiAlN coating for stainless steel and carbon steel (wear and high temperature resistance)
  • DLC or uncoated for aluminum alloy and copper (prevents material sticking)
• Machine tool conditions: Confirm internal cooling function and sufficient coolant pressure for temperature reduction and chip removal
