R32 6° With CNC Milling Tungsten Carbide Threaded Reaming Button Bit Description Reaming drilling tools are used when a large diameter is needed to be reamed out after a pilot holes is drilled to a depth. We manufacture pilot reaming drilling tools, domed reaming button bits and adapter reaming button bits. Pilot reaming bits consist of pilot adapters and reaming bits, both domed bits and adapter reaming bits are integral. Dome bit is usually used when the pilot bit needs to

R25 6 Degree 3.5" Shank High Strength Alloy Steel Reaming Button Bit Description Reaming bits were widely used in quarrying or mining for blast hole drilling, with pilot adaptors, the drilling direction can be ensured and accurate. Pilot holes are drilled depth and then reamed out to a larger diameter in a second pass required when hole diameter exceeds the capabilities of the rock drill and drilling tools available. • Widely used in drifting and tunneling • R25 thread system

R28 Spherical And Ballistic For Drifting And Quarry Rock Drill Button Bit Product Description Thread Button bit is well known for its high wear resistance on medium-hard to hard abrasive rock formations (between 200 Mpa to 260 Mpa compressive strength). Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture. • Color: Green,Yellow or Based on Customer requirements Product Name: Thread button bits Description: For

Tapered equipment affords drillers the ability to change drilling bits whilst still using the same drilling rod. Drillers choose tapered button bits for faster drilling penetration rate. Different taper sizes have different characteristics when it comes to the “knock-off” index – the smaller angle will prevent the bit from spinning. • Suitable for small hole range • Widely used in Dimensional Stone Quarrying Industry • Widely used in Underground Mining Industry • Color: Green
