The cutting teeth of the cone use TCI cutters or Steel tooth cutters. And the teeth have good wear resistance and the speed of the drill is fast. Intensive palm tip welding and full palm back protection, the cones are divided into back dimension and the diameter is protected by a protective design to effectively enhance the resistance of the drill bit.
Apply wear-resistant alloy or carbide tooth on the front stiffener or block surface. In order to reduce the weight of the rock reamer hole opener without affecting the support strength, the front centralization plate adopts a hollow design.
Precision-Engineered TCI Cones: Provides smooth and fast drilling with concentric hole opening.
Durable Cutter Types: Tungsten carbide inserts (TCI) or steel tooth cutters offer excellent wear resistance.
Hollow Centralization Plate: Reduces weight while maintaining strength.
Robust Design: Designed for long intervals and tough operations in medium-hard formations.
Easy Cutter Replacement: Hand-tool demountable cutters can be easily replaced, minimizing downtime.
High Wear Resistance: TCI cutters offer extended service life in abrasive conditions.
Efficient Drilling: Enables fast drilling speeds and effective hole opening.
Adaptability: Suitable for a wide range of applications, including hard shale and sandstone.
Long-Lasting Performance: Robust construction ensures minimal downtime and reliable operation.
Foundation Piling: Ideal for creating large-diameter holes for foundation piling in construction projects.
Directional Drilling: Perfect for horizontal directional drilling in medium-hard formations.
Rock Drilling: Suitable for drilling through tough rock formations like limestone and sandstone.
