Hi Gary, it may be difficult to say what you may need, without knowing the kind of projects you will be maiking. makes sense to say if you do the exact same theing the po did, you're in good shape. i cut out things more than i carve, so i use down cut 1/4" and 3/8" carbides a lot. what has worked for me is to buy the tooling as i need it.

it looks like you have a great start though!

@Gary Salisbury It looks like you are well set up for edge trimming and sign making.
If you do some edging you will need some 1/4 rounds, ogees,coves,and half rounds.If you are going to do rabbet, laps,or tongue and groove, you will need a set for that. also panel door sets for those in cabinets.

1. May I ask why you use down-cut bits? Isn't up-cut better because the chips get cleared out?

2. Here is the first project I will concentrate on - my Fly Box Templates. I wrote a book on how to make these templates for making wood fly boxes with a router but I find a lot of people want me to do it for them and a CNC seems to be the best way to reproduce them accurately. You can find it here on ROUTER FORUMS under the JIGS & FIXTURES category.

Down cut spirals are the opposite. They push chips downward which is why you need to be careful in a full cut not to go too deep. They are the bit of choice if you need a clean face because straight and upcut can leave fuzzy edges on the surface. The only sign making bit I didn't see on the list is the flat bottomed vee. There is a picture here of a similar one on amazon but this one has 45* sides and the Bosch one I have has 60* sides I think. https://www.amazon.com/HOEN-Window-...flat+bottom+router+bit&qid=1584561635&sr=8-84 They are good for leaving raised letters or objects.

Never rely on having just 1 of any bit, as you use any bit, put it on a list to buy a spare. I buy a lot from eBay seller “Drillman1” https://www.ebay.com/str/carbideplus, Freud and no-name Chinese are not the only sources.


Do not assume that the feeds and speeds in the Vectric Aspire tool library are correct for your machine, bits and materials. They should be considered placeholders and you will need to adjust to be appropriate for your use. The correct feeds are probably faster and speeds (spindle rpm) are probably slower than you would intuitively use. You want chips not dust, and bit should be cool enough to touch AFTER it stops.

Enjoy learning your new hobby!

Hi Gary, the 2 pockets on the left were cut with 2 different end mills (up cut carbides). the one on the right was cut with a 1/4" down cut spiral carbide. untouched pockets.

the warning was correct - you do not want to drill down with these down cut bits, but "spiral" down is ok.

i forgot to add, if you are having trouble with hold down on a part, the down cut will do more pushing down than lifting up as it cuts.

What does everyone recommend for a spoil board surfacing bit? I currently have a 1-1/4" 2-flute no name Chinese bit that has never been used so I don't know how or if it would work.

There appear to be a wide variety of designs and prices. I am thinking it probably would be best to get a 1/2" shank 2" bit for stability with that amount of mass. The next choice would be fixed or removable cutting surfaces. After that, how many cutting surfaces (flutes), 2 or 3 or 4?

From Amazon, this recommended 3-flute NITROMAK fixed bit is one of the most popular for $30 but I personally like a name brand products such as this 4-flute Whiteside fixed bit at $68.

What do you think? Comments and opinions, please......

I now understand. Good to know stuff. Thanks.
