    I have a post in the garden, 500mm high and 60mm diameter. I'd like to drill a matching hole in the bottom of a christmas tree so I can put it on the post.

    What is the best way to drill the hole? I figured a centre hole that a larger bit could follow would be best but there is little choice of anything close to that diameter.

    How big is this thing?
    60mm wide in a tree will require the hell of a trunk
    Therefore high, so you really need to think about safety

    Yeah thought about that but not sure it will be possible after a few inches deep. It does seem like the best option so far as the centre bit should follow a whole and keep it straight.

    A forstner bit will do it. You'll need an extension to go deep though.

    Xmas trees when freshly cut contain a high proportion of sticky sap, that. coupled with cutting deep in the end grain may cause a bits to overheat and jam . This could result in a less than straight parallel hole so the bit size would need to be well over the size of hole you need to compensate....you will only get one chance to get it straight, if not the tree wont fit over the post or will look like its pi$$ed:)
