R32 Cross Bit Description
R32 Cross Bits y R32 X Bits están diseñadas específicamente para los entornos de perforación con martillo en cabeza más exigentes. A diferencia de las brocas de botón estándar, los diseños de cuchilla en cruz y en X son la mejor opción para formaciones rocosas fracturadas, fisuradas o sueltas where “sticking” is a common risk.
Mediante la utilización de Acero aleado 45CrNiMo1V and high-grade tungsten carbide inserts, these bits offer exceptional durability and impact resistance. The robust blade geometry ensures excellent hole cleaning and maintains superior hole straightness, making them indispensable for mining, quarrying, and tunneling projects.
Características
High-Grade 45CrNiMo1V Steel: The bit body is forged from 45CrNiMo1V alloy steel, providing the perfect balance of hardness and toughness to resist fatigue and body breakage.
Anti-Sticking Design: The Cross and X-type blade configurations prevent the bit from getting wedged in rock fissures, a common issue in complex geological conditions.
Precision R32 Threading: Fully compatible with standard R32 drill rods and top hammer systems, ensuring maximum energy transfer and reduced thread wear.
Optimal Hole Straightness: The symmetrical blade design helps guide the bit straight through the rock, reducing deviation in deep hole drilling.
Wear-Resistant Inserts: Equipped with premium carbide inserts (16×10mm) that maintain their cutting edge longer in abrasive formations.

Aplicación
R32 Cross Type & X Type Insert Bits are designed for top hammer drills in:
Túnel y deriva: Ensuring precise hole alignment in fractured ground.
Minería: Excellent for production drilling in complex ore bodies.
Canteras: Ideal for primary blast hole drilling where rock layers are inconsistent.
Ingeniería Civil: Used for rock bolting and foundation reinforcement in unstable soil/rock conditions.

Mantenimiento
Blade Sharpening: Do not wait until the carbide inserts are completely flat. Regular sharpening of the blades maintains penetration speed and prevents stress on the 45CrNiMo1V body.
Protección del hilo: Always use high-quality thread grease. Check threads for wear or galling before every use to prevent stripping the R32 connection.
Flushing Check: Ensure the center flushing hole is clear. Poor flushing leads to “re-grinding” of debris, which rapidly wears down the inserts.
Rotation Speed: Adjust rotation speeds according to rock hardness. Excessive speed in hard rock can cause heat-checking on the carbide inserts.

PREGUNTAS FRECUENTES
Mientras que las brocas de botón son excelentes para roca sólida, R32 Cruz y X bits están diseñados específicamente para formaciones rocosas fracturadas o fisuradas. El diseño continuo de la hoja impide que la broca se atasque en las grietas de la roca, lo que garantiza una mejor rectitud del orificio y un rendimiento más fiable en condiciones geológicas complejas.
45CrNiMo1V es un acero de aleación de alto grado conocido por su excepcional resistencia al impacto y resistencia a la fatiga. En la perforación con martillo en cabeza, el cuerpo de la broca debe soportar miles de impactos de alta frecuencia por minuto; este material garantiza que el cuerpo de la broca permanezca intacto sin agrietarse ni romperse prematuramente, lo que prolonga considerablemente la vida útil de sus herramientas.
Según nuestras especificaciones estándar:
R32 Cross Bits: Disponible en diámetros de 50 mm (2"), 55 mm (2 1/6"), y 60 mm (2 3/8").
R32 X Bits: Disponible en diámetros de 55 mm (2 1/6") y 60 mm (2 3/8"). Todos los modelos incorporan de serie Tamaño del inserto 16×10 mm para garantizar un rendimiento de perforación constante.
Yes. These bits are manufactured with standard Hilos R32, making them fully compatible with all international standard R32 drill rods and top hammer drifters. This ensures a tight connection and efficient energy transfer from the rock drill to the bit.
While both are insert-type bits, the X-design provides a slightly different contact pattern with the rock, which can further reduce the risk of bit stucking in extremely loose or fragmented ground. Both designs utilize high-quality carbide inserts and the robust 45CrNiMo1V body to handle high-impact drilling.
