The LittleMachineShop.com HiTorque 6450 Mini Mill is the best in its class. It has the most power, the most torque, the most features and upgrades, and the largest table in its class. It is also proof that all mills are not the same.

Most noticeable is the LED mirror display which clearly and elegantly organizes the key controls for the mill. The panel features a start/stop button, spindle direction button, a Z-axis fine feed knob, and a variable speed knob. The fine feed has a resolution of 0.001" for precise milling operations. The spindle speed is displayed in a large easy-to-read digital display.

The 6450 mill also comes equipped with a 3-axis tablet display DRO connected via Bluetooth to magnetic scales on the table and column. The DRO system provides measures for the X, Y, and Z-axis in increments .0002" and comes factory installed on the mill.

A 500 Watt brushless spindle drive motor and belt drive provides tremendous power and low-end torque. There are NO gears in the spindle drive. The drive allows for spindle speeds from 100 to 2500 RPM continuously in both directions. NSK quality spindle bearings ensure smooth and quiet operation. An electrically interlocked spindle lock ensures easy and safe operation.

This mill has a solid dovetail column (it does not tilt side to side). This construction is significantly stiffer than the tilting column on other mini mills. This model also includes an air spring head support for even movement through the Z-axis range of travel.

The models 4190 & 6450 mini mills come equipped with an electrically interlocked spindle lock. This mechanism makes tool changes easier, faster and safer. When engaged, the plunger automatically drops into the locking hole as the spindle is rotated. An electromagnetic interlock disables power to the motor, locking the spindle. The HiTorque Mini Mill has drill press handles for drilling and fast motion of the mill's head. The R8 spindle ensures wide tool availability.

The large mill table has attractive aluminum hand wheels and 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. A latch handled cabinet provides easy access to control boards.

Chris' Tips

Take a look at the HiTorque 6450 mini mill in action.

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.

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 many 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 the user's guides for our machines.

Shipping

These machines ship by freight truck because they are simply too heavy and bulky for UPS Parcel Service. If your location will be difficult for larger truck/Semi-trailer, please let us know.

We normally ship truck orders a day or two after we receive the order. For local orders transportation usually takes no more than a day or two. For orders going across county or over water the transportation time can be up to a week or longer.

We add the following shipping cost to your order total:

We ship machines only to the US and Canada.

Destination	*Local	Continental US
Freight Terminal (pick-up) Within 50 miles / 1 hour of travel Note: Not all terminals allow pickup	$99	$179
Commercial Address (inc. Limited Access Sites) Set hours / No delivery appointment Includes limited access (e.g. Schools, Military, Gov. Bldgs) DOES NOT include liftgage service**	$99	$199
**Liftgate: Add liftgate if forklift or loading dock is not available onsite.		+ $50
Residential Address Includes delivery appointment and liftgage for ALL Residential businesses or limited access facilities (e.g. schools) requiring appointment or liftgage	$99	$249

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

**Liftgate service is included in local delivery and residential delivery. A loading dock or forklift is assumed in commercial deliveries. If these are not available, please add this extra service.

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.)

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).
Hemisphere Customs Brokerage which handles all customs clearance requirements. This is a flat fee of $108 on any shipment.
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.

Quotes

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.

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.
