The Model 4190 Deluxe HiTorque Mini Mill has all the features of our popular Model 3990 HiTorque Mini Mill, plus:

* 3-axis digital readout (DRO) with Bluetooth and 7" tablet display. The DRO is completely installed on the mill.

* Electrically interlocked spindle lock

* Machined aluminum handwheels and color keyed drill handles

The LittleMachineShop.com HiTorque Mini Mill for sale is the best in its class. It has the most power, most torque, and a larger table than other mills in its class.

This mini milling machine has a solid column. It does not tilt from side to side. This construction is significantly stiffer than the tilting column on other mini mills. This model also includes the air spring head support for even support through the Z-axis range of travel.

The 500 Watt brushless spindle drive motor provides tremendous low-end torque. And you can vary the speed from 100 rpm to 2500 rpm continuously. There are no gears to shift. And, with no gears, the HiTorque Mini Mill is the quietest in its class.

The large mill table provides 50% more table area than other mini mills. It also has 30% more travel in each direction. The resettable feed dials allow you to zero them at any point.

The HiTorque mini milling machine for sale has drill press handles for drilling and fast motion of the mill's head. It also has Z-axis fine feed with 0.001" resolution for milling operations.

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.

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

Chris Chris' Tips
Here's Using the Bluetooth DRO Display.

For more information on the Bluetooth DRO, visit the Bluetooth DRO Package page and the Android Tablet page.

You can compare the specifications for our mills.

Mini-Lathe.com has a review of our solid column mill.

The solid column is much more rigid than the tilting column.

Some people may feel that the tilting column is a feature, but I have used a mini mill for 10 years and never tilted the column on purpose.


Let's compare the LittleMachineShop.com Solid Column HiTorque Mini Mill to mini mills with a tilting column.

The tilting column on other folk's mini mills tilts 45 degrees from side to side. This has several advantages. First, it is possible to make some angled cuts. It's also easy to tram in the X-axis. One user (and only one) has described to me a cut that was impossible to make any way but using a tilting column.

This mill has a solid column. While it is harder to tram in the X-axis because you must use shims, it is not as easy to knock it out of tram as the tilting column mini mill. The solid column has thicker walls than the tilting column, and a stiffer joint where it joins the base, so the column is significantly more rigid than the tilting column.

LittleMachineShop.com no longer sells mills with a tilting column. That is an indication of how much better the solid column is.

Here are data sheets for the machines that we sell.

March 1, 2022 - Recent and unprecedented price increases in truck freight and gas prices, 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.

Notes

  • 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 thedelivery 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.
