The HiTorque 7x16 Mini Lathe is the best in its class. It has the most power, most torque, and a longer center distance than other lathes in its class.

The 500 Watt brushless spindle drive motor provides tremendous low-end torque. And you can vary the speed from 50 rpm to 2500 rpm continuously in both directions. There are no gears to shift.

The cross feed and compound rest dials are graduated in 0.001" and 0.025 mm. A 4" 3-jaw lathe chuck is included, and the lathe is equipped with a 4-way indexing tool post set for 5/16" (8 mm) tools.

Real top and bottom half-nuts and a reversible 16 TPI lead screw provide extended threading capability. You can create every American Standard Unified class 2A inch screw thread from 4 to 80 threads per inch, and you can create every American Standard Metric class 6h thread from 0.3 to 8 mm pitch with the extra 21 tooth change gear that is included. Cutting inch threads is made even easier with the factory-installed threading dial.

This HiTorque 7x16 Mini Lathe for sale includes a chip tray, a backsplash guard, and spreaders to give the feet a broader stance.

This machine is shipped completely assembled and adjusted. Machined surfaces are coated with a viscous oil to prevent rust. It wipes off easily with a rag--no solvents necessary.

The model 5100 HiTorque Mini Lathe is a version of the SIEG SC2.

*NOTE* We ship machines only to the US and Canada.

Chris Chris' Tips
View a comparison of the specifications for our lathes.

See what the difference is between the SIEG drive system and the HiTorque drive system.

With this lathe, you can create every American Standard Unified class 2A inch screw thread from 4 to 100 threads per inch, and you can create every American Standard Metric class 6h thread from 0.25 to 8 mm pitch with the extra 21 tooth change gear that is included.

But you can actually make more thread pitches than that. And, there are more change gear combinations than those shown in the users guide. To see what you can really do, see the Change Gear Calculator.

Why our mini lathes have plastic change gears

First, a couple of notes:

  • Our HiTorque machines do not have the plastic gears that break. When you read about mini lathes and mini mills breaking plastic gears, the vast majority of cases involve the two-speed gears inside the head. HiTorque machines, with the brushless DC drive, have a belt directly from the motor to the spindle. No gears at all in the spindle drive.
  • Our larger HiTorque bench lathes have no plastic gear at all. Every gear is metal. HiTorque mini lathes do have ABS plastic change gears. Here are the reasons:

  • Plastic gears are quieter than metal gears. Metal change gears raise the sound level to an objectional level.
  • Plastic gears are appropriate to this application. They work fine and when you crash your lathe, they provide an inexpensive, easy to replace “mechanical fuse”.
  • Plastic gears are more economical. We choose not to charge extra for a basically worthless feature.
If you prefer metal change gears, we sell a Metal Change Gear Set.

These machines ship by truck because they are simply too heavy and bulky for UPS Parcel Service. We normally ship truck orders a day or two after we receive the order. We add the following shipping cost to your order total:

March 1, 2022 - Recent and unprecedented price increases in truck freight, especially to residential addresses, has required us to increase the cost of our truck freight. We hope the future will see a return to normal and historical costs, but until then freight delivery costs have increased. 

  Local Far West Other Continental US
Delivery to freight terminal (within 50 miles/1 hour) $125 $125 $155
Delivery to commercial address $99 $135 $165
Delivery to school or secured location $99 $175 $195
*Liftgate (added to any above) Incl. + $50 + $50

Delivery to residential address (includes appointment & liftgate)

$99 $175 + $50 = $225 $195 + $50 = $245

"Far West" refers to ten western states: CA, OR, WA, AZ, NV, ID, UT, NM, CO, WY.

"Local" refers to the parts of Southern California served by Hollywood Delivery Service.

For delivery to Alaska, Hawaii, or Puerto Rico, we will check with several trucking companies to get the best price and then call for your approval before we ship.

We ship machines only to the US and Canada.

Canadian Shipments

Truck Freight shipping to Canada involves 3 distinct charges in addition to the product costs. (All amounts are in US Dollars, see the current mid-market exchange rate.)

  1. Canadian Provincial Taxes (GST, PST, HST) depending on which province the shipment is going to. This will be 5% - 15% added to total sales amount depending on province (Canadian Sales Tax).
  2. Hemisphere Customs Brokerage which handles all customs clearance requirements. This is a flat fee of $108 on any shipment.
  3. Truck Freight from Southern California to destination in Canada. This is generally $300-$500 for residential liftgate delivery and appointment for single machine + tooling orders. Delivery to a terminal for pick-up or a commercial location with loading capabilities can reduce this cost substantially.


To get a quotation that includes the shipping costs, add the products you want to the shopping cart and continue the checkout process until you reach the Payment page. On the Payment page, select the Quotation option. We will add the shipping costs and return a complete quotation to you within one business day.


  • Only 1 charge for entire pallet (up to 700 pounds total). The shipping charges shown above cover the cost of shipping the machine and anything else that you purchase with it, including a second (or third) machine, stand, tooling, and accessories. 
  • A "commercial address" has a company name, a public entrance and posted hours of operation. If you do not have a forklift or loading dock at your place of business, you must add the liftgate fee. If you are running a business at your residence without a public entrance and posted company name and hours of operation it is considered a residence and a not commercial address.
  • Schools, colleges, universities, university hospitals, military bases, government facilities and other secured locations are charged a limited access fee that is included in the amounts in the chart above.
  • If you choose Terminal Pickup, and there is not a terminal within 50 miles (or 1 hour), we will confirm with you that you still want Terminal Pickup. Terminals tend to be off highways (usually miltiple intersecting) and industrial centers. Only certain terminal allow pick-up. 
  • Liftgate service is included in the residential delivery fee. The trucking company will call you to schedule the delivery.

Some carriers offer Inside Delivery which gets the machine inside one doorway or into your garage. If you select this we will confirm availability before shipping:

  Local Far West Other Continental US
Inside Delivery

Gets the machine inside 1 threshold (NO stairs, NO gravel, NO tight corners, etc.)

This is simply pushing pallet jack to move crate a little closer to destination or up driveway into garage. NO Uncrating. NO Setup.

Once shipment in transit carrier can not change service or refund charge. CALL IF QUESTIONS...
