Conical slotted type

The conical slotted type is generally used for large crushing hammers phi; After heat treatment, the core hardness of slotted drill rod is enhanced, so the wear resistance is better. The slotting in the tip is also more conducive to the gas and dust discharge from the tip of the drill rod during the impact, reducing the impact resistance of the drill rod and making it easier for the drill rod to cut into the breaking point. This type of drill rod is suitable for mining, especially for mine geology with high viscosity.
