Bigger. Stronger. Faster.
The LittleMachineShop.com HiTorque Large Bench Mill 6700 is our largest mill -- a significant step up in size, rigidity, and power compared to a mini mill, or even our bench mill. This benchtop mill provides a larger table, more travel, and more horsepower.
A 1000 watt (1-1/3 hp) brushless DC motor provides abundant spindle power and tremendous low-end torque. A simple belt change switches between low range and high range, giving you continuously variable spindle speeds from 80-5000 rpm.
The 29.1" x 7.1" (740 mm x 180 mm) table provides a large work area.
The HiTorque Bench Mill incorporates a true quill and drill press-style handles for easy drilling. A button on the end of each handle reverses the spindle to make tapping easy.
Like our smaller mills, the 6700 HiTorque Large Bench Mill has an R8 spindle for wide tool availability.
The control panel includes a digital spindle speed display. A separate display provides digital position readout for the quill.
A handy magnetic "tool box" on the side of the column provides a convenient place for the spindle wrench and drawbar wrench.
This mill is a version of the SIEG SX3.5.

These machines ship by truck because they are simply too heavy and bulky for UPS Parcel Service. We normally ship truck orders a day or two after we receive the order. We add the following shipping cost to your order total:
Other Continental US
Delivery to commercial address
Delivery to school or secured location
Delivery to freight terminal
Delivery to residential address (includes liftgate)
"Far West" refers to ten western states: CA, OR, WA, AZ, NV, ID, UT, NM, CO, WY.
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.
We ship machines only to the US and Canada.
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.
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.
The shipping charges shown above cover the cost of shipping the machine and anything else that you purchase with it, including a second (and third) machine, up to 700 pounds total.
A "commercial address" has a company name, a public entrance and posted hours of operation. If you do not have a forklift or loading dock at your place of business, you must add the liftgate fee. 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.
Schools, colleges, universities, university hospitals, military bases, government facilities and other secured locations are charged a limited access fee that is included in the amounts in the chart above.
If you choose Terminal Pickup, and there is not a terminal within 30 miles, we will confirm with you that you still want Terminal Pickup.
Liftgate service is included in the residential delivery fee. The trucking company will call you to schedule the delivery.
We offer inside delivery which gets the machine inside one doorway or into your garage:
