Bosch AXT 25TC - Our Electric Garden Shredder of the Year 2017, 2018 and 2019

The Bosch AXT 25TC is now the second most widely reviewed garden shredder on Amazon behind only its smaller, more racous sibling – the Bosch AXT 2200 Rapid.  It has accumulated 289 reviews and enjoys a 4.3 star rating.

To maintain that sort of approval rating compared to all other garden shredders on Amazon is nothing short of astounding.

You will have gathered – we love this machine.  If only it weren’t quite so expensive.

The Bosch AXT 25TC boasts 2500W of garden shredding power.  It is not the most powerful shredder we have reviewed but its unique cutting mechanism delivers an incredible 230kg/hr shredding capacity.

If you have read our reviews of impact and quiet shredders you will know that impact shredders are best for softer green waste but may stall if presented with larger pieces of dry, woody waste.  Quiet or crusher style shredders are excellent for crunching up woody waste but can become blocked by too much green waste.

Enter Bosch’s unique Turbine cut. These shredders deploy the side plate and crushing action seen in the quiet shredders to dispose of tough woody waste.  Smaller green, wispy cuttings can pass between the blades on the turbine and get chopped up in that manner.  It is the complete electric, garden shredder.

Bosch calls the AXT 25TC mechanism the Turbine Cutting system. What it has got to do with turbines escapes me.  The cutter more resembles a cylinder cut lawnmower.

As the cutter rotates the blades trap the larger cuttings against the side plate and use the same sort of cut and crush approach as the quiet shredders.  Smaller clippings and waste drop between the turbine blades and are chopped up as they pass through.

As the blades don’t need to move at such high speed as the impact blades from the rapid shredders.  Consequently turbine cut shredders are not too noisy – 89dB.  That’s about a third of the noise from a typical impact shredder.  Worth noting, it is still more around triple the sound intensity of the Bosch AXT 25D quiet shredder – 82dB.  You should wear ear protection when using this shredder.

OK, so much with the description on how they work but, are they any good?  We’ll get on to that but for now here are the technical details.

Manufacturers Description

A 3 in 1 universal shredder for all your shredding needs. The powerful 2500 Watt induction motor significantly increases throughput to 230kg per hour whilst minimizing blockages. The touch pad control panel also helps prevent blocking via its “pulse” reverse mechanism, making the shredder easier to operate and control.

This innovative turbine cutting system is designed to shred large volumes of branches, shrubs and green material of up to 45mm in diameter. It also features a 53 litre collection box with a patented interlocking mechanism to make handling and storing shredded material simple and safe. It also includes a patented detachable hopper for convenient self-feeding and compact storage.”

Is it Any Good?

The Good

The Bosch 25TC is a distinct improvement on both the usual crusher and impact type shredders.  Waste is chopped more finely than crusher shredders and, unlike impact shredders, they do not jam on knotty branches.  You can even expect to shred right up to the quoted maximum allowable diameter.

Trust us – 45mm is getting up to small log size.  It is quite something to put something of that diameter through an electric garden shredder.

These shredders seem reasonably quiet in operation and certainly seem to live up to their quoted noise figures.  You won’t have to use ear defenders for short periods of use – a real boon on a hot summer day.  If you are going to use it regularly or for any period of over 2 hours you are strongly advised to wear ear protection.

The ability to shred bigger branches undoubtedly has something to do with the higher throughputs these machines can achieve. We always look at the manufacturers quoted throughput figures with a touch of scepticism – after all, you are trying to push all of your cuttings and waste through a slot that is much smaller than most letterboxes.  However, the Bosch AXT 25TC seems to happily cope with large shredding jobs.  Some of this might be down to the feed hopper which seems much easier to feed than other shredders.

As with all Bosch products the 25TC seems solid and well built.  If you do have a problem Bosch’s customer service is excellent.

The Not so Good

I think we have to address the biggest shortcoming of these shredders head on.  You certainly get what you pay for – the Bosch Turbine Shredders are the best electric shredders on the market right now. Sadly there is no escaping the fact that these machines are expensive.  You can reckon on paying at least 50% more than for an equivalent quiet/crusher shredder.  That’s likely to be more than 3 times the cost of an impact shredder.

Put another way, you could buy the Bosch AXT 2200 Rapid for your finer, green cuttings and an AXT 25D for your woody waste for about the same price!  We know people who have done this but it isn’t much of a solution for most of us.

As with quiet machines these have to be pretty solidly built to deliver the cutting power required.  Consequently these too are heavy machines.  They are also a bit top heavy so there is a tendency for them to tip over when you move them around the garden.

We have commented on the length of the supplied cable before.  Four metres may not be mean but it doesn’t allow you to reach the corners of even a relatively small garden.  Under load these machines could be drawing upwards of 10 Amp current.  Make sure you have a heavy duty, waterproof extension lead so you can easily move your shredder to where you want to do the shredding.

In operation the only complaint we here is that smaller cuttings and green waste don’t really get broken up enough.  It;’s not much of a problem as the bits are still small enough to breakdown as compost pretty quickly anyway.

Should you buy it?

In a word – yes.
There can be little doubt, the Bosch 25TC sets the standards against which Electric Garden Shredders should be reviewed.  When set up well it will consume vast amounts of just about any plant waste you can through it.

For many people the only thing that should hold you back is the price.  You do get a lot for your money though and, with Bosch’s record on delivering quality products you should continue to enjoy reliable shredding for many years to come.

So, if you have a medium to larger garden, need to shred mixed woody and green garden waste, and you can afford it, choosing the Bosch AXT 25TC is going to be a great choice.

Turbine Cut Shredders - The top alternatives

This is an extremely short section.  There are no Electric Garden Shredder alternatives to the AXT 25TC.  The turbine cut technology is proprietary to Bosch and is presumably covered by several patents.

If you want something that can compare or exceed the throughput capacity of the AXT 25TC you are going to need to look towards a petrol shredder.
