Bosch Professional GFF 22 A review

The professional biscuit jointer that publishes its cutting depth and ships with the cutter and a dust bag.

The end of it The best-specified jointer here, and the one that costs the most to be so.

Every figure is a manufacturer specification, read off the listing itself, and the judgments are ours — drawn from how the specification behaves in this class of machine and from what long-term owners consistently report. Where a figure is missing, we say so rather than fill it in.

What the specification says

22 mm (0.87 in) maximum cutting depth, supplied with a 105 × 22 mm (4.13 × 0.87 in) cutter, a dust bag and a two-pin wrench. Part number 0601620070.

Publishing the depth is the differentiator

Three biscuit jointers on this page, and only this one states the number that defines what it can do. That is worth something on its own: a specification a manufacturer prints is one it can be held to.

On the dust bag

Treat it as packaging rather than as extraction. The port it attaches to is the useful part — connect it to a workshop vacuum and the machine becomes far cleaner to use. See the extraction reviews above for which kind of vacuum suits a narrow port.

Availability

No such listing: the American Amazon shop answers the reference with a search box rather than a page.

Read from Keepa on the day this page was last revised; stock and price both move without notice.

The good side, and the catch

Strengths

  • Publishes its cutting depth, which neither the Triton nor the Makita does
  • Cutter and dust bag in the box

Compromises

  • The most expensive jointer here
  • Not sold on amazon.com
  • A dust bag is the weakest form of extraction — connect it to a vacuum instead

What comes up most often

Why does 22 mm (0.87 in) of depth matter?

It sets the largest biscuit size the machine can seat, and therefore the thickest stock it can align well. Standard biscuits run to size 20; a machine that reaches 22 mm (0.87 in) of depth handles the whole standard range with margin. It is the specification that separates a jointer from a slot cutter with a fence.

Is the supplied dust bag any use?

For occasional cuts, it stops chips filling your shoes. For anything sustained, connect the port to a workshop vacuum instead — a bag on the tool fills fast and does nothing about the fine fraction, which is the part worth capturing.
