Our custom cemented carbide gundrill deep hole drill bits deliver exceptional performance for demanding deep hole drilling operations. Engineered with premium cemented carbide materials, these tools provide superior hardness, wear resistance, and heat dissipation capabilities for precise results across various industrial applications.

Manufactured from high-quality tungsten carbide, these drill bits offer extreme hardness and exceptional wear resistance. The material composition ensures efficient heat dissipation during deep hole drilling, maintaining cutting edge integrity and dimensional accuracy.

Featuring a central coolant hole and optimized flute geometry, our gundrill design enables continuous high-pressure coolant flow for effective cooling, lubrication, and chip evacuation. This prevents clogging and ensures straight, accurate holes.

Available in diameters from a few millimeters to several centimeters with customizable lengths, flute geometries, and shank designs to match specific machine requirements.

The combination of cemented carbide material and optimized design delivers exceptional durability, reducing tool replacement frequency and minimizing production downtime.

• Aerospace: Drilling deep holes in turbine engine components for cooling channels and fuel systems
• Automotive: Manufacturing engine blocks, cylinder heads, and transmission parts
• Machinery Manufacturing: Precision drilling in spindles, gears, and housings
• Oil & Gas: Drill bits, downhole tools, and pipe manufacturing

Install in CNC or dedicated deep hole drilling machines with proper shank clamping. Connect coolant supply system to ensure continuous fluid flow at required pressure. Regular inspection for wear, cleaning of coolant holes, and proper storage ensure optimal performance and extended tool life.
