To add drilling in hard material, two suggestions. First get a little bit of cutting oil to reduce the heat buildup.
Second is use a high quality drill such as a milwalkee right angle drill, something that has a lot of torque. Then use a floor jack under the drill to apply the enough pressure to load the drill down but not bog it down. Make sure to ease off the pressure when you start to notice the point coming through the back side or some serious damage can result.
Of course, alternate and best method would be to remove the spring to drill on a full size drill press.
