The HiTorque Deluxe Bench Mill 6550 is the deluxe middleweight in our mill lineup. A significant step up in size, rigidity, and power compared to a mini mill, it is approximately 100 lbs. lighter than our large bench mills. Weighing in at 245 lbs., this mill can be placed on a bench with the help of some friends and its base dimensions of 9.1" x 16.1" will fit on most benches.

The deluxe features added to this HiTorque bench mill include:

- A 3-axis tablet display DRO connected via Bluetooth to magnetic scales on the table and column. The DRO system provides accurate measurement for the X, Y, and Z axis in increments 0.0002" and comes factory installed on the mill.

- Electrically interlocked spindle lock for easy, safe tool changes

- Machined aluminum handwheels

Like our other HiTorque bench mill, the model 6550 has the following standard features:

A 750 Watt (1 hp) brushless DC motor provides abundant spindle power and tremendous low-end torque. The drive allows for spindle speeds from 100 to 2500 RPM continuously in both forward and reverse. A belt drive from motor to spindle eliminates any failure from gears breaking. NSK quality spindle bearings ensure years of quiet operation.

The combination of a large table (27.6" x 6.3") and extensive travel along X, Y, Z-axis (19.7", 5.7", 11.8") provides a large work envelope. Precision ground ways ensure smooth and accurate movement. Adjustable gibs are on all dovetail ways. A fine feed knob on the Z-axis provides for precise control.

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.

A digital spindle speed display and a separate digital depth gauge 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 0.001") provide accurate readings. Ball thrust bearings on feed screws ensure smooth movement.

At, 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 SX2.7 built to specifications.

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

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.

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.

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 ( or similar may be able to help you pack up a machine, or move it into your home/shop.
