So I’ve been cutting all of my long centerboxes with a Probox bit. It’s a bit of a hassle, but not too bad. But I want to get a bigger router bit that cuts a little deeper and can stand up to many stringers specifically for cutting the hole for the longer centerboxes. I started looking at router bits online and I’m more confused than ever (http://www.amanatool.com/routerbits.html). Because I’m not a router bit guru, I’m asking the experts for their advice. And I’m willing to get away from High Speed Steel (HSS) bits and go with carbide tipped, if that’s recommended.
Hey Gunkie, Not real sure what the problem is, but here goes: The best choice (to me) is a 1/2" shank spiral upcut bit, carbide, in a plunge router used with a rub collar on the base plate. Either upcut or downcut spiral is better than straight flute. Some makers have a three flute carbide straight that will work. These are the best choices. Having said that, you can get by with an end mill cutter for less cost. Carbide will outlast HSS but is way more brittle so DON'T bump it against anything or it will chip. Whatever you choose, still take the stringer down in small increments and slowly so it won't grenade on you. hope this doesn't confuse the issue. There are A LOT of choices in this arena.
ps. Amana bits are as good as any other make. They have been around for years. The solid carbide slow spiral bits are VERY good but pricey and worth the cost in the long run.
Gunkie, I forgot to mention a speed control for the router if it isn’t variable speed. They have inexpensive ones at Harbor Freight for less than $20 US. Don’t know how good they are but it should have an in-line fuse for protection. These are VERY handy for the high rpm’s of a router. Only use them on a motor with brushes. An induction (brushless) motor will blow it out.
ps. Were you an RTO at one point? I’m assuming that is Morse.
