Frequently Asked Questions

Q1: What are the main thread types available for bench drilling tools? We offer 9 primary thread types: R3212, R32, HL38, T38, T45, T51, T60, ST58, and ST68, covering a wide range of production requirements.

Q2: Can these button bits be used with reaming products? Yes, our comprehensive range includes button bits, cross bits, and reaming products that are fully compatible with standard drilling rods and shank adapters.

Q3: What is the benefit of using "Retrac" type button bits? Retrac bits are designed with special grooves to help extract the drill string in difficult or fractured rock formations, significantly improving hole straightness and recovery speed.

Q4: What diameters are available for ST68 reaming bits? Our ST68 reaming bits are typically available in diameters such as 152mm (6"), designed for enlarging pilot holes in production drilling.

Q5: How does the flushing hole configuration affect performance? The number and placement of flushing holes (front and side) are optimized to efficiently clear rock chips from the bit face, reducing wear and preventing overheating during high-speed drilling.

Q6: Are these tools compatible with large-scale production drilling? Absolutely. Our range covers everything from 1” rope threads to heavy-duty GT60 and ST68 threads, making them ideal for high-productivity bench drilling and large-scale mining operations.
