I have an outside facing wall on the second story of my home. I'm trying to drill above a window to put a support for a curtain rod.
I can easily drill about 1/5 of an inch but then the drill just spins. From the picture I took it looks like wood. I imagine this is OSB or plywood. I am using a 1/4 inch carbide tipped masonry drill bit.
Any ideas on how I should either set this curtain rod or drill 1/10 of an inch further so that I can place the anchor? If I don't need an anchor how should I be thinking about using shorter screws to support the weight of likely heavy curtains?
