The lubricating film in synthetic esters in PolairDrill is much more durable than basic mineral oil films. This is not a marketing statement – it is fact. Lab tests have proven that PolairDrill can support loads of more than twice as much as mineral oil. When combined with extreme pressure and anti-wear additives, PolairDrill provides synergistic protection against heat build up and wear. As temperatures increase in drills, regular rock drill oils rapidly lose lubricity. As lubricity decreases, friction increases, and heat builds up. As heat increases, lubricity continues to decrease until regular rock drill oils fail and form carbon and varnish, promoting increased wear.

PolairDrill has been engineered to withstand temperatures up to 200F. (>90C) higher than regular rock drill oils, providing wear protection long after other rock drill oils.

Why don’t other rock drill oil manufacturers use synthetic esters?

Most lubricants are part of an overall package of various oils and fuels (hydraulic, gear, transmission). Buying decisions typically are made based on price. Synthetic esters are expensive, often costing 5 times as much as basic mineral oils. Just adding a small amount of ester into a formulation will only make a marginal difference in lubricant performance. PolairDrill formulations are based on lab wear tests to determine the optimum ratios to provide excellent protection at justifiable costs.

When actual use cost is taken into account, PolairDrill can cost less than $1 per hour more to use than regular rock drill oil. The benefits of more reliable drill performance and the ability to break rock without worrying about drill breakdown end up making PolairDrill a wise buying choice.
