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.

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.

Additional Notes

  • Contact and delivery. Ensure you choose the correct type of delivery, have a dedicated contact person/number, and are ready on day of delivery. Freight companies charge an additional fee if delivery exceeds 30 minutes.
     
  • Only one shipping 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 machine, stand, tooling, and accessories.
     
  • A "commercial address" has a sign with company name, a public entrance and posted hours of operation. 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.
     
  • A "limited access" designation is required for "Secured Locations" (schools, colleges, universities, university hospitals, military bases, government facilities, etc). Please provide accurate details on delivery in special instructions.
     
  • "Terminal Pickup" allows for pickup at local terminal. If 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 near highways (usually miltiple intersecting) and industrial centers. Only certain terminals allow pick-up.
     
  • "Residential delivery" does not include moving machine into home/garage/workshop or any setup. Delivery is to start of driveway on the street that the delivery truck can access. (See inside delivery below.)

 

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.

 

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.

Inside Delivery

For many years we have offered INSIDE DELIVERY for an added charge (as set by freight carriers). Unfortunately, most carriers have stopped this practice for liability, cost, or other reasons and we can no longer reliably offer it. If you really need Inside Delivery, please give us a call and we can try to help with your specific situation. Our recommendation however has always been to call some friends or find someone local. Saves some money and lets you meet the neighbors.... 

Alternatively, companies like Navis Pack & Ship (www.gonavis.com) or similar may be able to help you pack up a machine, or move it into your home/shop.
