      Is this good for 4? sewer line cleaning applications?
      ByAug 10, 2023
      1 Answer | 
      Answer This Question

      This drill is designed for high-torque applications like drilling large holes and mixing materials. However, it's not specifically designed for sewer line cleaning. For sewer line cleaning, specialized equipment like drain augers or pressure washers are typically recommended.

        Does this tool come with a case or is there a case available for this?

        Answer This Question

        Mine did not come with a case. Haven’t looked for one either. Put mine in a padded soft sided cooler case that was laying around gathering dust. It does the job just fine.

          Hi Douglas! The 1/2 in. 450 RPM Compact Drill ( 1660-6) is a tool-only product.

            Mine just came in a cardboard box. Might have to build a box for it.

                If you own one of these: Does the Milwaukee 1660-6 drill have a variable speed control dial? Contradictory answers, one owner says no and posted a photo of theirs straight from the box. Milwaukee rep wrote that it does. The Milwaukee factory manual indicates only the 1623-20 (apparently discontinued) model had this feature. Just want to know. Thanks.

                      Unfortunately answer by Milwaukee Electric is wrong. I just opened the box with 1660-6 it is fixed single speed 450 rpm. Direction can be changed. Download the manual and see for yourself - single speed. Or read my review below with pictures. "Made in China".

                          Very good for mortal. I mix drywall mud dozens of times a day and never an issue. My last one lasted 10 years and I abuse it daily.

                                Milwaukee broke twice drilling railroad ties. Rated for 1.5” wood bit used a 5/8”. 1st stripped shaft threads holding chuck in reverse. Paid shipping to repair. Took 6 weeks. 2nd time sheared reverse chuck screw. Got refund, bought Makita 1/2” Spade H drill 9 amps. Drilled 8 holes in 23 ties with 5/8” bit. You can’t drill railroad ties without reversing especially old ties which are 7x9 oak/locust and throughly impregnated with creosote. Get the Makita, save time, hassle and get the job done.
