Kannastor GR8TR V2 Series 5pc Grinder

Kannastor has been making high quality Grinders since 2003. That’s quite a bit of experience and all those years have been spent designing and tweaking grinder technology. Kannastor easily has a reputation of creating some of the most advanced designs on the planet today. A crack team of designers and engineers work tirelessly to ensure that all their grinders work at the highest possible level – no more stiff and squeaky grinders.

TIP: Kannastor offers a limited lifetime warranty that cover manufacturer defects – including broken teeth, for any reason.


All Kannastor Grinders are crafted using Aero-space grade 60/61 hardened (anodized) Aluminium, making them extremely durable and able to withstand being knocked about. All parts are chemically bathed, anodized and then each are closely hand inspected to eliminate any potential defects and impurities. Kannastor kind of takes your health and safety personally.

An innovative micro teeth and dish press design (MTP) whereby the teeth shred from top to bottom while simultaneously gently pressing through grinds. This is an effortless process as less force is required than with some other grinders, making this grinder an excellent option for users with medical conditions. Incredibly easy to clean, simply wipe down the teeth with a damp wash cloth.

Friction/Residue Rings work to reduce the friction creating an “air ride”. These rings also act as a residue collectors.

The GR8TR Series Grinders are modular by design. This version has 5 pieces you can very easily build up or break down to whatever size you need. 3 non-negotiable factors were incorporated into the design of these sleek innovative grinders. All were achieved and then some.

  • Effortless grinding action
  • Increased storage capacity
  • Customisation

An extremely unique feature is the inclusion of 2 grinding plates offering you 2 varieties of grind. I love this feature as the consistency of your herb plays a big role in your enjoyment, no matter how you like to use your herb! These plates are easily interchangeable. Whichever plate you are not using can be stored underneath the top lid or removed entirely.

Standard Plate A medium coarse grind, perfect for rolling or pipes
Vape Plate A finer grind, has multiple small holes for your herb to fall through

Being modular you are able to assemble and configure your GR8TR in many ways.

  • Grind your herb at home then remove the plates and you now have a storage container.
  • For out and about storage you can break down the GR8TR into the size of a puck that will easily fit in your pocket.
  • Remove the top plate (storage for spare plate) and store your fresh buds awaiting grinding.

Basically, play around/customise and make the GR8TR your own.
