Build it out

One arm for every attachment

Every Torus takes a standard 1.5-inch tooling arm, so each attachment rides its own and swaps without tools, and every one you add to an order counts toward the bundle discount.

One arm per attachment. Swap in seconds.

  2. Adjustable work tableSet the angle once. Grind all day.1.5-inch aluminum tooling arm

  • Fits every Torus grinder and most 2×72s built around a 1.5-inch arm
  • two knobs lock each arm

The arm-mounted attachments each ride their own 1.5-inch solid aluminum arm, so they drop straight into any Torus grinder and swap in seconds.

Eligible attachments and wheels save 5% at 2 units, 10% at 3 units, 15% at 4 units, 20% at 5+ units. A grinder counts as one unit; only eligible parts are discounted.

Values marked on the figure: 5% at 2 units; 10% at 3 units; 15% at 4 units; 20% at 5+ units; 1/2 to 1.5-inch rubber small wheels.

The tool-arm receiver on a Nebula: two tubes, one above the other, and two knobs lock each arm. Belt attachments go in the top tube; the work table goes in the bottom one.

Not sure which?

Three machines, one decision.

Every Torus uses the same machined billet-aluminum dual-axis tracking head. The Nova and Nebula add a 9x12-inch base and a taller frame, so choose by frame size, material and budget.

Compare the three grinders
Classic, $995
Machined 6061 on a compact 9x9-inch base: tilting chassis, stainless ratchet tension, 1.5-inch arms. The machine that built the name.
Nova, $1,295
6061 aluminum with cross-bracing rods on the 9x12-inch base. Lighter to tilt and move, and corrosion resistant.
Nebula, $1,295
The Nova in 3/8-inch steel. More mass, less vibration. Pick it if the grinder gets bolted down and stays there.
Steel closeout, $845
The steel machine, fully assembled and tested. Was $1,195, limited quantities.

Footprint and frame height

The Classic stands on a compact 9x9-inch base and clears a motor up to 12 inches long at horizontal; the Nova and Nebula stand on a 9x12-inch base with a taller frame.

Before you order

Shipping, lead time and returns.

Straight answers, the same ones you would get if you emailed me.

How fast does an order ship?

Most orders ship in seven to ten business days from time of order. A more detailed delivery estimate will be given upon ordering your grinder. Every grinder is built to order; accessories, backlog or custom powder coat can add time. You get a tracking number the day it leaves Sterling.

What does shipping cost, and do you ship outside the US?

Domestic shipping is calculated at checkout. Grinders are heavy, so international orders are quoted per order: email me your address and what you want and I will send you a rate. Local pickup at 1741 Industrial Drive Unit #8 in Sterling, Illinois is also an option.

Can I return a grinder?

Contact me first, within two weeks of arrival, and I approve returns case by case. Because every machine is built to order, approved returns carry a 25% restocking fee, you cover insured return shipping, and the original shipping is not refunded. Full terms are on the returns and warranty page.

What is covered by the warranty?

I warranty the non-wear parts of the grinder against defects in materials and workmanship under normal use. Belts, wheels and other wear items are not covered, and neither is damage from misuse or modification. Motors and VFDs carry their manufacturer's warranty and I walk you through any claim.

Do I need to buy a motor from you?

No. The grinder price is the chassis, and you can add a motor and VFD package at checkout or run your own. If you are sourcing one yourself, the budget motor and VFD page lists what I would buy.

How do I pay?

Card, Apple Pay, Google Pay, Link, Cash App and Amazon Pay, or pay over time with Affirm, Klarna or Afterpay, all at checkout over Stripe. Your card number never touches this site.

Still deciding

Ask the guy who builds them.

Tell me what you grind and how much room you have, and I will tell you which machine to buy, including when the cheaper one is the right answer.
