Ø20.1 mm × 820 mm Deep Hole Gun Drilling Tools
Production CharacteristicsThe dia 20.1 × 820 mm deep hole gun drill is a precision-engineered tool designed for high-accuracy internal drilling operations. With a single-flute structure and inner coolant channel, it enables efficient chip evacuation and stable cutting performance.
Key Advantages:
•High dimensional accuracy and excellent surface finish
•Stable chip evacuation and reduced tool wear
•Replaceable carbide inserts and guide pads for lower maintenance cost
•Robust construction for long service life
•Excellent straightness in deep-hole drilling
This tool is configured with one TPGT1403RG carbide insert and two GPS-06-20-085 guide pads, ensuring smooth guidance, extended tool life, and excellent hole straightness and surface finish.Made from high-strength alloy steel and heat-treated for durability, the gun drill is compatible with single-tube systems and uses internal high-pressure coolant to deliver superior cooling and chip removal. The insert and guide pad combination provides reliable cutting with minimal vibration, making it ideal for medium-depth drilling tasks.Application Materials:Suitable for drilling a wide range of materials including carbon steel, alloy steel, stainless steel, cast iron, and aluminum alloys, commonly used in automotive, mold making, aerospace, hydraulics, and general machining industries.
