Benchtop tablesaws can handle dadoes

Q:

 I recently purchased a Bosch 4000 benchtop tablesaw and wanted to buy a dado blade for it. When I went into a woodworking store to purchase one, the store owner said that a dado blade was unsafe for a benchtop tablesaw. He said the saw isn’t heavy enough. Do you agree with his warning?

A:

 Unless you’re cutting something extremely heavy or unwieldy, Tony, the 4000 should be able to handle most dado chores using an 8" blade set. We were able to mount a 78 " dado in the 4000 we recently tested. For added capacity, mount the narrower of the two washers nearest the motor, advises Michael Williams, Bosch benchtop tools product manager. Using a shop-made zero-clearance insert, we managed a maximum blade height of 218 ". Bosch’s dado set accessory (part #TS1007), which includes a table insert and instructions, cuts a maximum 1316 " dado up to 218 " deep. For added stability while making cuts—including dadoes in long boards or full panels on any portable saw—enlist a helper or use outfeed supports to control workpieces.
