In my experience hand drills can be difficult. Having the right material, good form and good conditions makes all the difference in the world. When I was trying to learn hand drill about 18 years ago, I was using a piece of willow on cottonwood. My friends and I tried together for days with no success. Then someone told us to try mule fat which is a baccaris and we got a coal right away. Basically anything with a pithy center like elderberry, a flowering stalk like mullein or even cattail can work. You have to find a good one that is not too thick or two thin on the outer wall. It is also a lot easier to get a coal on a hot day in the sun then when the sun is going down and the air is getting more moisture in it. I still struggle with it today unless I have an epic set. I like to use something soft for the baseboard. California buckeye is what I usually use but I am sure there are a lot of good options where you are. Even with a good set though I often get blisters and for that reason and because it can be fickle until mastered, I prefer the bow drill. The other tip for hand drill that I was taught was to just work on your form for a month or so before trying too hard to get a coal. Make sure both hands are working evenly. I think in general you have to do it a lot. I know a lot of folks and who get a coal a few times and think they have it down. Even though I have made a lot of fires by friction, I still struggle and fail sometimes. Then I reevaluate, get some different material and try again until I get one.
Good luck!

By the way, I once led a class on friction fire that my dad came to. It was the middle of a hot day and I gave him a really good hand drill set. He tried and got a coal in under a minute on his first try. He said, "wow, that is a lot easier than I would have expected." I was thinking about how long I struggled to get my first coal and just shook my head. Lol.
