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

AMG Solid Carbide Internal Cooling Straight Flute Drill is engineered for demanding deep hole drilling operations in structural components. Manufactured from high-quality ultra-fine grain cemented carbide and precision-ground, this drill offers exceptional hardness, wear resistance, and chipping resistance for long-term high-speed drilling performance.

• Internal cooling design directs coolant to the tool tip, reducing heat buildup
• Efficient chip evacuation prevents blockages and tool jams
• Optimized for deep hole and blind hole applications
• Precision-ground for high accuracy and surface finish

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

The internal cooling channel delivers high-pressure coolant directly to the cutting area, rapidly dissipating heat and reducing thermal deformation. The straight flute design enhances chip evacuation, preventing accumulation that could cause tool jamming while ensuring drilling continuity and minimizing vibration.

• Combined cooling and chip removal system solves heat accumulation in deep holes
• Maintains excellent hole straightness and diameter consistency
• Precision-ground cutting edges for fast, smooth operation
• Ideal for batch processing with high efficiency and low failure rates
• Extended tool life reduces change frequency and improves productivity
• Custom OEM solutions available for specific requirements

Ideal for deep hole drilling in mechanical structures, mold cooling channels, and fixture holes. Meets precision requirements for carbon steel, stainless steel, aluminum alloys, copper alloys, and other metal components.
