Chris Chris' Tips
DISCONTINUED - This HiTorque Mini Mill has been replace by the 3990 HiTorque Mini Mill, Solid Column with Air Spring.

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.

The LittleMachineShop.com HiTorque Mini Mill does not come with a drill chuck as many other mini mills do. That's because the drill chucks provided by the factory do not meet our quality standards (read: they're junk). We had them put the value of the drill chuck into other parts of the mill, like the large X-Y table that is unique to LittleMachineShop.com.

Get one of these drill chucks and you will be in business.

Here are data sheets for the machines that we sell.

Here's what you need to convert the HiTorque Mini Mill to CNC. (But be sure you look at the CNC milling machines that we sell before you start).

Here are the user's guides for our machines.

Shipping

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:

. Local Far West Other Continental US
Delivery to commercial address $59 $115 $145
Delivery to school or secured location $79 $155 $175
Liftgate, additional Incl. $20 $20
Delivery to freight terminal $115 $115 $145
Delivery to residential address (includes liftgate) $79 $175 $195

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

"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.

For Canadian shipments we will provide an all-inclusive quotation for shipping, brokerage, and taxes. The brokerage fees are $108. The taxes vary by province. If you have a customs broker or want to self-clear customs please let us know.

We ship machines only to the US and Canada.

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:
