Let’s dive right into learning about the various Tormek grinding stones and how to choose the right one for your sharpening needs.

One of the most popular grinding stones offered by Tormek is the Original Grindstone (SG-200 or SG-250). This stone is made of aluminum oxide and is ideal for sharpening knives, scissors, and chisels.

Another option is the Blackstone Silicon (SB-250), which is perfect for high-speed steel and other exotic alloys.

If you’re looking to sharpen Japanese tools, the Japanese Waterstone (SJ-250) is a great choice for its unique abrasive properties that ensure a sharp and polished edge.

Finally, Tormek also offers a Diamond Wheel, which is the most efficient option for sharpening carbide and other extremely hard materials.

Original Grindstone (SG-200 or SG-250)

Looking for the OG grindstone to take your material removal game to the next level?

Look no further than the legendary SG-200 or SG-250. These bad boys are made from aluminum oxide, so they’re tough as nails and will give you that polished finish you’ve been dreaming of.

The SG-200 is the star player of grindstones, with an 8-inch diameter that perfectly matches the Tormek T-4.

The SG-250 is a powerhouse with a massive 10-inch diameter designed for the Tormek T-8.

These babies can handle just about any tool you throw at them – woodturning tools, knives, scissors, and many more.

Let’s not forget about the stone grader that comes with the Tormek sharpeners.

You can transform these grindstones from a gritty 220 to a silky smooth 1000.

Talk about versatility!

It’s like having a shape-shifting grindstone that can do it all. No wonder it’s the perfect sidekick to the Tormek sharpener T-8.

To ensure the peak performance and longevity of the Original Grindstones, it is crucial to keep them pristine and perfectly flat.

The TT-50 truing tool can effortlessly restore the grindstone’s surface to its former glory, bidding farewell to any unsightly grooves or hollows that may have dared to form.

With tender love and care, your Original Grindstones will remain loyal companions for countless years, consistently providing you with unparalleled sharpening results.

Blackstone Silicon (SB-250)

You’ll love the versatility of the Blackstone Silicon (SB-250) grinding wheel, as it’s suitable for sharpening everything from high-speed steel to carbide and even ceramic.

This wheel is designed to efficiently remove material, making it perfect for sharpening tools with hard metals. The Blackstone Silicon has a grit size of 220, which makes it ideal for shaping tools and repairing chips or nicks.

When it comes to polishing and finishing, the Blackstone Silicon (SB-250) grinding wheel does an excellent job. It falls under the polishing/finish category, which means it can create a smooth and polished finish on tools.

The wheel is also efficient for sharpening common tool steels, making it a great choice for sharpening a wide range of tools.

The Blackstone Silicon (SB-250) grinding wheel never loses shape, so you don’t have to worry about truing it like you would with a traditional grindstone.

However, if you do need to adjust the characteristics of the wheel, the SP-650 Stone Grader can be used to change the grit of the wheel.

Keep in mind that the stone grader is not for use on diamond wheels and the coarse side should not be used on Japanese Waterstones.

Japanese Waterstone (SJ-250)

If your workshop is lacking the Japanese Waterstone (SJ-250), then you are truly missing out.

This must-have tool is essential for achieving the sharpest edges on any of your tools.

Handcrafted from natural stone, the SJ-250 boasts a fine-grit surface that is ideal for giving your chisels, planer blades, and knives that final touch.

Not only will it sharpen your tools, but it will also polish and refine the edges, leaving them in top-notch condition.

I’m talking about achieving an extremely smooth, reflective surface.

But what truly sets the SJ-250 apart is its water usage. By utilizing water, this stone stays pristine and dust-free, enabling you to work efficiently and flawlessly.

This precision makes it a go-to for those working with the finest materials.

But one important note: never use the coarse side of the stone grader on your Japanese Waterstone.

I bet you’ll never want to harm your knife.

Overall, if you’re looking for a high-quality sharpening stone that can help you achieve a razor-sharp edge on your tools, the Japanese Waterstone (SJ-250) is an excellent choice.

Looking for a more efficient way to remove material from your tools? Check out the Coarse (DC-250) option from Tormek’s selection of grinding wheels. This grinding wheel is perfect for shaping and re-shaping tools as it removes material at a faster rate than finer stones.

  2. This wheel is designed to be used on common tool steels and works particularly well on HSS (High-Speed Steel) materials.
  3. The Coarse (DC-250) has a grit size of 360, which means it is rough enough to remove material quickly, but still leaves a smooth surface finish.
  4. All Tormek diamond wheels have fixed grit that cannot be changed using the stone grader (SP-650).

With the Coarse (DC-250) grinding wheel, you’ll be able to save time and work more efficiently when shaping and re-shaping your tools. Plus, you won’t have to worry about the wheel losing its shape or becoming dull over time.

This diamond grinding stone, with grit 600 is designed to produce a polished edge on your tools, making it ideal for those who require a high-quality finish.

To help you determine if the Fine (DF-250) option is right for you, here is a table comparing the key features of the Coarse (DC-250) and Fine (DF-250) grinding stones:

Grinding Stone Material Removal Polishing/Finish Tool Steel Suitability HSS/Hard Metals Efficiency
Coarse (DC-250) High Coarse Good Good
