roughsawn Posted December 22, 2022 Report Share Posted December 22, 2022 Can't find one at Taylor Tools, or Amazon. Can you guys recommend one...and where to get it, for my table saw? For clean half lap joints, and dados on the table saw. Thanks! Quote Link to comment Share on other sites More sharing options...
pkinneb Posted December 22, 2022 Report Share Posted December 22, 2022 I think Freud makes a box blade set. 1 Quote Link to comment Share on other sites More sharing options...
Barron Posted December 22, 2022 Report Share Posted December 22, 2022 Some rip blades are flat topped, and the box joint set is very good. Quote Link to comment Share on other sites More sharing options...
roughsawn Posted December 22, 2022 Author Report Share Posted December 22, 2022 Ya, I found couple 24T flat top blades, and I have one. Just wondering if anyone makes a 50T or 60T flat top for crosscutting. Quote Link to comment Share on other sites More sharing options...
Just Bob Posted December 22, 2022 Report Share Posted December 22, 2022 I use Ridge Carbide. Great blade good service. Quote Link to comment Share on other sites More sharing options...
Ronn W Posted December 22, 2022 Report Share Posted December 22, 2022 I used Forrest 40T cross cut " special grind". Spendy but a very good blade. Quote Link to comment Share on other sites More sharing options...
Chestnut Posted December 22, 2022 Report Share Posted December 22, 2022 I just use the 24T freud industrial flat grind. Regardless of the blade you should score / use a marking knife on your cuts as well as using a backer board or sacrificial fence this will prevent blow out and tear out more than anything. You don't really need more teeth if the blade is sharp. I've done a LOT of half laps and joinery with that blade and it's still sharp. I clean it very regularly probably every project. Heck i was too lazy to swap that blade out and did an entire project with that blade as my cross cutting blade, no issues there. 2 Quote Link to comment Share on other sites More sharing options...

gee-dub Posted December 22, 2022 Report Share Posted December 22, 2022 A dado set is going to be your flexible answer for dados. For grooves I use a 50T 'groover' made by Carbide Processors; others make them as well. If a 24T rip is not crosscutting as cleanly as you are after many makers will custom make a blade for you. For off the shelf . . . FTG rip blades, box joint sets or dado stacks are the rule of the day. Here's a 40T FTG from Ridge similar to the custom 50T I have. 1 Quote Link to comment Share on other sites More sharing options...
Wimayo Posted December 22, 2022 Report Share Posted December 22, 2022 Cross cut blades are designed to cleanly cut perpendicular to the wood fibers using alternate top bevel. Rip blades are designed to chop through the fibers, chisel like, running parallel. Combination blades are designed as a compromise to cut with less efficiency both ways. They are called combination blades because they usually have sets of 4 teeth with alternate top bevel for cross cutting and one flat top tooth for chopping. As a result, a combination blade will make the cuts you need with a fairly flat bottom; some better than others but usually good enough with a bit of fine tuning with a shoulder plane or sandpaper block.

roughsawn Posted December 23, 2022 Author Report Share Posted December 23, 2022 All good info, guys. Thanks, that clears it up for me. I have a brand new CMT flat top rip blade that I will use for half laps. Quote Link to comment Share on other sites More sharing options...

Tom King Posted December 23, 2022 Report Share Posted December 23, 2022 The Dewalt, surprisingly, dado set has the cleanest bottoms of grooves of any of my dado blades. Such joints are fine off the blades. It doesn't have the deep corners either, like a Forrest dado set does. One reason is the arbor hole is a very tight fit, and not that easy to get on and off, but the machining seems to be dead on. Quote Link to comment Share on other sites More sharing options...

roughsawn Posted December 29, 2022 Author Report Share Posted December 29, 2022 That's the dado stack I have. Does a beautiful job on quarter quarter drawer joints. Quote Link to comment Share on other sites More sharing options...
