The main airflow cylinder channel and the exhaust of the S250-M3 have been engineered to allow for efficient actuation of the drill. The new design drives more of the drill’s energy to the face of the rock, which reduces vibration and the amount of energy the driller’s body has to absorb.
Boart Longyear’s global product manager John Nielson says, “A drill operator stated that it was the first time he could feel his hands and feet after using a rock drill for a full shift. The S250-M3 reduces the noise level by 6 decibels, which results in half the noise.
“When compared to the leading competition, the S250-M3 showed a 50% reduction in noise level, 39% increase in torque, and a gain of more than 6 inches in penetration per minute at 110 PSI. The components of the S250-M3 also experience less wear due to the decreased vibration, which allows the drill to operate longer without repair and reduces rebuild costs.”
The S250-M3 comes in three primary variations to match specific customer needs - jackleg, stoper and sinker. The drill hex chuck ends are available in both 22mm and 25mm.
Safety is incorporated into the design process of all Boart Longyear products and the S250-M3’s noise suppression and lower vibration result in less user fatigue. Boart Longyear also recommends a comprehensive hearing conservation program to effectively deal with elevated noise levels.
