High Accurate Solid Carbide Coolant Deep Hole Drill Bit 90-93Hrc For Steel Drilling

The AMG solid carbide coolant-through straight flute drill is engineered for deep hole drilling in structural components. Manufactured with premium ultra-fine grain solid carbide through precision grinding, it delivers high hardness, exceptional wear resistance, and superior anti-chipping performance for stable cutting and precise hole accuracy in structural deep hole applications.

The innovative coolant-through design delivers cutting fluid directly to the cutting zone, effectively reducing temperature, improving chip evacuation, and extending tool life for stable, efficient deep hole drilling operations.

Ideal for deep hole and blind hole drilling in structural components including:

• Mechanical structures
• Hydraulic structures
• Mold deep cooling channels
• Fixture deep holes

Meets high-precision requirements for carbon steel, stainless steel, aluminum alloys, copper alloys, and other metal structural components.

• 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

The AMG coolant-through straight flute drill delivers high-pressure coolant directly to the cutting zone through internal channels, effectively reducing cutting temperature and thermal deformation while lubricating the cutting area. The straight flute design provides excellent guidance during deep hole drilling, ensures smooth chip evacuation, and prevents clogging for stable, efficient, low-vibration continuous machining.
