The LittleMachineShop.com HiTorque 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. 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.

The lathe includes a chip tray, a backsplash guard, and spreaders to give the feet a broader stance.

The LittleMachineShop.com model 4100 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.

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 do 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.
