3″ Warrior Yellow Range DTH Hammer and Button Bits

The 3″ Warrior Yellow Range Hammer is the smallest hammer in our range, designed for demanding down-the-hole (DTH) drilling applications such as water well boreholes and production drilling in hard rock formations. Built from high-quality materials, it delivers high drilling efficiency at low operating pressures, helping reduce fuel consumption while maintaining strong performance.

Engineered for durability, this hammer is designed to withstand continuous drilling in challenging conditions while minimizing downtime and maintenance.

Shank & Thread Specification

The 3″ hammer is available with the following configuration:

• 3.5 Shank – 8 Spline
• Connection Thread: 2 3/8″ API REG

Matching button bits are available in different sizes to suit the required hole diameter. Always ensure the correct bit is used with the hammer to maintain performance and avoid equipment damage.

Button Bits

Our DTH Button Bits are fitted with tungsten carbide inserts, providing exceptional hardness and wear resistance for efficient rock breaking and optimal energy transfer during drilling.

Compatible bit sizes:

• 95 mm – 105 mm (3.7″ – 4.1″)

Using the correct size bit is important to maintain drilling efficiency and equipment reliability.

Important Button Bit Considerations

• Correct Bit Size: Always use the recommended bit size for the hammer to ensure efficient drilling and avoid unnecessary stress on the equipment.
• Oversized Bits: Oversized button bits may cause bit breakage, shank damage, or equipment failure. For larger hole diameters, it is recommended to use a larger hammer.
• Sharpening: Keeping button bits sharp improves drilling efficiency, reduces fuel consumption, and extends the lifespan of the bit.

Hammer Maintenance & Service

Proper maintenance is essential to maximize hammer performance and service life.

• Lubrication: Ensure the hammer is properly lubricated and serviced regularly to maintain peak performance.
• Routine Inspection: Regularly inspect components and replace worn parts such as the chucknut when necessary.
• Correct Tools: When opening the hammer, always use the correct tools such as a breakout bench, suitable spanners, and a copper hammer (never a steel hammer) to avoid damaging internal components such as the sleeve, piston, and chucknut.
