Welding type deep hole gun drill

Welding type deep hole drill（gun drilling）It is currently the most commonly used type of deep hole drill. The drill bit is made of hard alloy, and the drill rod and shank are made of heat-treated steel. The drill bit, drill rod, and drill shank are welded together as a whole. Compared to solid alloy deep hole drills, welded deep hole drills also have better cost-effectiveness, so they are currently widely used in China.

Welding type German TBT deep hole drill (gun drill) is currently the most widely used product. Single blade deep hole drill (gun drill) can achieve very high aperture tolerances, surface smoothness quality, and very high concentricity, which makes deep hole drill (gun drill) have a higher application range in the field of precision machining. It can replace the traditional process of drilling first and then twisting, and also has strong processability.

In actual production, due to the high-precision drilling capability of the single blade gun drill, the German TBT welded deep hole drill is also suitable for shallow or medium depth machining holes, which also increases its range of use.

The current range of applications for welding type German TBT deep hole drills
Common drill bit diameter range: 2.0-50.0mm
Overall length of deep hole drill: up to 6000mm

Cutting fluid must be used (deep hole drilling specific cutting oil is recommended)
Filtering accuracy: 10-20 µ m
Viscosity: Ø 1.9-50mm
