Thread: Bosch GHO 26-82 Professional Planer - Snipe!

Send it back: not of serviceable quality.

I have contacted the store where I bought it and they are getting in touch with Bosch.

Am I right in my assumption the blade height should be the same as the rear base plate? What is the setup on other planers or does anyone own this model that can comment?

There must be some adjustment somewhere! If not, the blades would not be able to be sharpened at all - and would have to be manufactured very exactly , as would have to be the alignment of the rear sole in relation to the spindle... hard to believe....

The blades can't be sharpened and are disposable. The have two edges so you can flip them once dull. They are fixed in position with the intent to make setup easier (just fixed in the wrong position it seems). A tongue (on the spindle) and groove (on the blade) locks the blade into position then two grub screw tighten the blade down.

The second photo shows the height difference with a straight edge. Hard to see in the photo but the blade is a fair bit higher than the rear base plate.

The cutting tips ahold just "kiss" your straight edge as illustrated. If the edge moves at all the cutters are incorrectly adjusted.

Maybe it needs the blade holders adjusted.

Quality tools used to have the sole plate machined after assembly to ensure truth to the cutters.

If I have the tool upside down with the straight edge on top and move the cutterhead by hand the blade lifts the straight edge and moves it forward about a cm. Its is much more than just kissing it but this is hard to see in a photo.

The store I bought it from contacted bosch who said there is no way it should be like that. They are sending out a replacement.

Got the new planer today but it has exactly the same problem as the last. I have asked for a refund and will look for something else.



Does anyone have suggestions for other models to look at?

What do you want to do with it?

Builders universally use Makitas. Others skite about their Festools. I have an 850w version, which is beautifully designed but physically very large and cumbersome.

My favourite is a discontinued AEG model which uses 102mm TCT disposable blades. The 4" cut, the retractable blade guard and it's one handed operation make an unbeatable combination in my opinion.

I also have an old Elu and a beautifully made Metabo. The latter in particular is also a beut with 900w of power, a swivelling dust spout and full wave electronics in one of the smallest and lightest packages on the market. A true one handed planer, with a still useful 82mm cut.

The AEGs are still available occasionally ex Germany and I've seen a couple of Metabos recently on flea bay. One for about $350 ish, which given it's features & performance, it's proper old fashioned steel case and Metabo's three year warranty is an absolute bargain in my opinion.

I probly won't use it very often after i finish the deck which is why I went for the bosch for only around $220 which had some good features on paper (dust/chip ejection from either side with a standard extractor port). The store I bought it from is getting in touch with bosch again to check if this was part of a bad batch and whether they have one without this issue.

>10 years later, it seems that nobody at Bosch cares enough to fix it. I got one cheap in a dented unopened box, so happy to play around. Considering replacing the drum with helical cutter drum like this:

I have an old Bosch green PHO 25-82, made in Europe, to compare. It is as it should be. Blade tip barely scratches a straightedge on the rear baseplate. Adjustable front baseplate has a slight nose up orientation.

The GHO 26-82 blade protrudes too far. The blade appears to be a conventional double sided planer blade with a fixed groove in the drum. So have to shim the baseplate up and figure out how to calibrate the nose plate.

Mass produced tools intended to produce accurate results must be assumed to be poorly setup. Years ago my Metabo compound slide saw was not square and needed tuning. Only found out after cutting some picture frames which came out twisted on assembly. Festool track saw was also not square out of the factory. This didn't make a noticeable difference unless jointing cut boards edgewise. So now, I trust nothing which is not certified to be calibrated.

So there was daylight down the gap between the depression in the blade and the hump on the drum that locates the blade. Undoing the blade holder and making sure the blade was pushed in when tightening has put the blade closer to a correct position.

Now there is daylight between the blade and a straightedge on the rear baseplate. Nose plate is 0.15 mm or so above the baseplate and flat rather than nose-up 0.2mm.

If anything the baseplate mount could do with a tad shaved off it. At this stage will wait until I decide if I should acquire a helical blade drum for the hand planer or the planer thicknesser I don't have yet.

Actually the old "non-professional" PHO 25-82 appears a superior design in every way to the "professional" 26-82 with the possible exception of motor technology. The drum is larger at 55mm and made of machined aluminium vs layered plate steel. Blade mount appears reliable and precise. Rebate capacity is 24mm vs 9mm.
