atb-r saw blade recomdation?

[brett gallmeyer]

I'm in the need to bye a 10'' saw blade that makes a flat bottom cut. full kerf or 1/8 kerf however u want to say it. i want to use this blade for cutting tennons and for cuttiing slots for splines in boxes and frames. i've looked at freud so far, the 50t abt-r combination blade. so what do my fellow creekers recomend?

[Jason Whitaker]

Ridge Carbide TS2000 has the atb-r config you are looking for and I might add it is a fantastic blade. Cuts as nice as my WWII, in some instances maybe even better.

And to think I get to live only 20 minutes away from Forrest and Ridge... gotta be some good in NJ for woodworkers!

If you need a flat bottom go with a FTG grind. It may not be as common as ATB, but it's still available.

FTG is fine for ripping, but generally crosscuts poorly.

Infinity (http://www.infinitytools.com/departments.asp?dept=1026) also has good ATB+R blades.

[Bill Huber]

But an ATB will not make a flat bottom, correct?

To get a flat bottom you have to have an FTG, correct?

Hey Bill, long time.http://fototime.com/4E9AFF4732A76C5/orig.gif


If you want a true flat bottom you will need to use a rip blade [FTG]. An ATB blade will give you a close to flat bottom but it won't be a true flat bottom.

How are things going ......

I thought that was right, Brett stated he wanted a flat bottom but also stated he wanted an ABT-R which he couldn't have with that ABT..

[Leo Graywacz]

Going good Bill. Just a little slow right now because of the economy. The phone has been ringing more lately, 3 calls today. More than in the last 2 months.


The ATB-r blade has 4 pointed teeth, alternating and then one flat ground tooth. You will get a mostly square kerf with it but the points on the alternating bevel teeth you will get slight digs on the outer part of the kerf. Usually about .006"

Forrest has a "special" WW-II grind that gives a flat bottom. It is designed for finger/box joints and such. It isn't cheap at $125, however (10" size).

If you're cutting the cheeks of tenons, you need a rip blade which has a flat tooth grind.

You should be able to get an industrial blade for about $60.

The above blade should also cut slots for splines just fine.

Regards, Rod.

The -R is a raker tooth every so often that cleans out the cut to a flat bottom.

It should give fine service for a slot cutting blade and I have heard nothing bad about Ridge carbide but haven't personally used any.

Brett,

If you opt for a Freud blade be sure you get either the LU84M011 (Silver I.C.E. Coated) or the LU84R011 (PermaSHIELD Coated). These are the full kerf (0.126") with ATB-R grind.

Look closely at the specifications for the Freud Blade., I have an LU82 and it cuts like a dream. The only problem is the ATB teeth are about .020" taller than the raker teeth so it leaves a ridge in the corner.

The ridge is pretty easy to remove with a sharp chisel, but it is an extra step.

A ripping blade works fine for the cheek cuts on tenons as it is more of a rip cut than a cross cut.

Flat top (FTG) is the only true flat grind. An ATB/R is flatter than an ATB, but still leaves slight "bat ears" because the ATB tips protrude slight above the flat raker.

Freud LM72, Infinity 010-024, DeWalt/Delta 7642 or 7124 are excellent 24T FTG rippers

ATB/R:

Freud LU84, Infinity Combomax, Tenryu RS25550 are excellent ATB/R 50T combo blades

Bat ears:p -- What a great way to describe it.:D

Hi Brett,

Have you had a look at our new flat top grind blades that are made for fine cross-cuts? We offer them in two kerfs, 1/4" and 5/32". Soon we will have spacers that you can put in between the two blades to make 3/8" wide grooves with flat bottoms.

Please see the link below.

The picture you posted is for a TCG(triple chip grind). Typically used to cut melamine. The illustrations Scott posted below are correct for FTG & ATB-R.
