R25 35mm Rock Drill Button Bit
The R25 35mm Rock Drill Button Bit is engineered for efficient rock drilling in mining, quarrying, construction, and general drilling applications. It combines high-quality tungsten carbide buttons with a forged alloy steel body to deliver reliable drilling performance and exceptional wear resistance.
High-Quality Tungsten Carbide Buttons
High-strength tungsten carbide inserts provide excellent wear resistance and impact resistance during continuous rock drilling operations. The optimized button configuration ensures effective rock penetration and stable drilling performance.
Precision Forged Steel Body
The bit body is manufactured from premium alloy steel and processed through precision forging and heat treatment. The reinforced construction delivers superior structural strength and durability under demanding drilling conditions.
Efficient Rock Penetration
The R25 threaded connection ensures secure compatibility with corresponding drilling rods and tools. The 35mm drilling diameter is ideal for small-diameter rock drilling applications requiring efficient penetration and accurate hole formation.
