i have a set of those countersinks that look like a cone with a hole in them. they work okay but me being an idiot i dulled the one i need yesterday. i have no idea how to resharpen it, and honestly, they don't work all that well (i only paid about $15 for the set of five).
so i need something new. i looked at the Enco site and there are a variety of countersinks. there are single-flute HSS, six-flute carbide, and a nifty one that takes carbide inserts (for a correspondingly nifty price, but made in the USA). i have no problem paying the price for the one with the inserts if it is actually better. i do a fair bit of countersinking and i am at times a little heavy-handed. will the one with the inserts hold up? also, can i use it in a good drill press, or must it be used in a milling machine? these will be used in pretty much any material you can think of (steel, aluminum, brass, plastic, maybe even wood).
thanks,
andy b.
PS-so, how DO you sharpen one of those cone-shaped countersinks?
