The LittleMachineShop.com HiTorque Large Bench Mill 6770 is our largest mill. It is a significant step up in size, rigidity, and power compared to a mini mill, or even our other bench mills. This bench top mill provides a larger table, more travel, more horsepower, and more rigidity. Compare our standard features and specs to others in this size and price range.

A 1000 Watt (1-1/3 hp) brushless DC motor provides abundant spindle power and tremendous low-end torque. NSK brand Japanese-quality spindle bearings ensure years of quiet operation. A belt drive from motor to spindle eliminates any failure from gears breaking. A simple belt change switches between low range and high range, giving you continuously variable spindle speeds from 80-5000 rpm.

A factory installed, hard wired 3-axis DRO with easy to read display. Magnetic scales are mounted on the table and column. The DRO system provides accurate measurement for the X, Y, and Z axis in increments 0.0002".

The combination of a large table (29.1" x 7.1") and extensive travel along all axis (XYZ: 20.2", 8.5", 11.8") provides a large work envelope. Precision ground ways ensure smooth and accurate movement. Adjustable gibs are on all dovetail ways. Fine feed on Z-axis for precise control.

The mill has a solid (No-Tilt) head and rigid rectangular dovetail column which maintains head alignment (tram) at any height, ensuring years of rigid and "true" milling. Power head lift to raise or lower the mill head with the touch of a button. A handy magnetic "toolbox" on the side of the column provides a convenient place for the spindle wrench and drawbar wrench.

The mill has an R8 spindle for wide tool availability. A true quill and drill press-style handles make for easy drilling. Tapping-mode is another standard feature with a button on the end of each handle allowing you to reverse the spindle to make tapping easy. Electrically interlocked spindle lock for easy, safe tool changes

Standard features include a digital spindle speed display and a separate DRO for the quill which reads in inches and mm. You can automatically resume running at the last-used spindle speed. Spindle fine feed and position lock are also standard.

Large anodized handwheels on the X and Y axes and 10 TPI lead screws (Accurate to .001″) provide better accuracy readings than metric conversions. Ball thrust bearings on feed screws and split nuts on X and Y axes minimize backlash and ensure much smoother movements and less backlash.

We stand behind every machine we sell. If it’s not right, we’ll make it right and we have the in-house technicians and replacement parts in our U.S. warehouse to back it up.

*This mill is a version of the SIEG SX3.5 built to LittleMachineShop.com specifications.

**WARNING: At over 350 pounds, you and your buddies can't lift this onto your bench. You will need an engine hoist, forklift, or other mechanical assist to move this machine.

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

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.
