  • The Tormek T-8 Original is bigger and heavier, and has a stronger motor capacity compared to the Tormek T-4 Original .

    The bigger Tormek T-8 Original has a larger grinding wheel of 250 mm (9 7/8") diameter that runs at 100 rpm, compared to 200 mm (7 7/8") and 140 rpm for the Tormek T-4 Original. The Tormek T-8 Original also has a larger honing wheel of 215 mm (8 1/2") diameter compared to 145 mm (5 3/4") for the Tormek T-4 Original.

    The bigger and heavier format of the Tormek T-8 Original makes it more suitable for the bigger and heavier jigs, such as the DBS-22 Drill Bit Sharpening Attachment, the SVH-320 Planer Blade Attachment which might feel unstable on the lighter and more compact Tormek T-4 Original.

    The warranty  for both machine models is 8 years (5 years + 3 years, upon registration within 90 days from purchase). However, when the Tormek T-4 Original is used for commercial, industrial or educational purpose the warranty is 2 years, while the full 8 year warranty applies to both non-professional and professional use on the Tormek T-8 Original.

    The Tormek T-8 Original comes with a couple more jigs and accessories than the Tormek T-4 Original. The SE-77 Square Edge Jig, the TT-50 Truing Tool, and the T8-00 Storage Tray for Tormek T-8 Accessories are included with the Tormek T-8 Original and not in the Tormek T-4 Original.

    Enclosed both with the Tormek T-8 Original and the Tormek T-4 Original is the HB-10 Tormek Handbook, the PA-70 Honing Compound, the WM-200 AngleMaster, the EM-15 Edge Marker, and the SP-650 Stone Grader.

    It is important to think about what kind of tools you will sharpen with your Tormek machine. We recommend the larger models for sharpening of drill bits and planer blades, due to the power and stability of the Tormek T-8 models. If you are a woodcarver or hobbyist and mainly sharpen smaller tools you might find the Tormek T-4 models more convenient.

  • I got the T4 a couple weeks ago and it is such an incredible machine. I think if your'e a beginner then the T4 is definitely more than enough! I was lucky enough to meet a really nice guy Sebastian in the store and he taught me so much in just 5 minutes. Merci Tormek!

  • I need to sharpen and re profile some axes and knive. Knive from saber grind to Scandi. Axes to carving axes so long 28-31degree angles. Which one would be best for me? t4 or t8? Id also start sharpening people’s knives as second income. 
    Lease let me know!

  • Hi Rob,

    Thank you very much for your email and for sharing so much detail about your sharpening plans. We really appreciate you reaching out—and it’s great to hear about your interest in axes, knives, and content creation on TikTok and Twitch. An in-depth review is always exciting to hear about.

    Based on what you describe—reprofiling knives from saber grind to Scandi, sharpening carving axes with long bevel angles, and offering knife sharpening as a second income—we always recommend the Tormek T-8 for professional or semi-professional use.

    The Tormek T-8 is our most robust machine, designed for demanding work and extended use. It features:

    • more powerful motor for consistent torque, even under heavy pressure
    • larger 250 mm grinding wheel, which is especially beneficial for reprofiling and maintaining consistent bevels on axes
    • An 8-year warranty, reflecting its durability and suitability for professional sharpening services
    For anyone planning to sharpen knives for others or use the machine as part of a business, the T-8 is the clear long-term choice.

    If you have any further questions about setups, jigs, or angles for your specific applications, feel free to reach out—we’re always happy to help.

    Sébastien
