These directions will assist the user in properly cutting stainless steel tubes.

Inline Design recommends using a cold saw, band saw, preferably oil-fed. These saws will leave minimal burr and no heat marks. For round tubing, use 65S Stainless Steel Pipe Cutters.

For demonstration purposes, Inline Design is providing directions based on the use of the cut-off saw.

Caution: Wear protective ANSI-approved safety glasses, work gloves, and masks all the time.

Tools Required

  1. Cut-off saw
  2. Duct tape
  3. Abrasive disk/blade
  4. Paper towel
  5. Disk sander
  6. Inner/outer reamer tool*


  1. Place duct tape on the clamp of the cut-off saw and to all other areas where the tube will touch the metal to protect the surface from getting scratched while being cut
  2. Mark cutting point, clamp the tubing in place, and commence the cut
  3. Immerse the cut end into water to cool the cut tube
  4. File any sharp edges evenly with a fine metal file
  5. Clean the tube using a paper towel and some household cleaner
  6. Note: if necessary, ream/deburr the outside and inside of the tube. Be careful not to scratch the tubing while deburring; keep the deburr tool straight
  7. To polish the cut, follow instructions for maintaining stainless steel surface

NOTE: A small amount of surface corrosion is not uncommon after exposure to weather or salty conditions. We recommend using our passivation solution to prevent any surface corrosion from happening; more information is available on our Engineering Specifications Page.

  1. Mount the posts to the floor or the brackets to the wall before installing the handrail tube. Please refer to other instructions document found on our website for help in that operation
  2. Place the handrail tubing on the saddles. Mark the drilling points using a marker
  3. It’s very important not to skip this point otherwise the drill bit will skid. Remove the handrail then place it on a working table. Mark the drilling points with a center punch tool. Repeat this several times in the same location to give a good guide for the drill bit.
  4. Use the corresponding drill bit size shown in table above.
  5. Apply cutting fluid on the drill bit.
  6. Hold firm but without pressing too hard the hand-drill then gradually apply pressure to drill through the top rail with stopping a couple of times to reapply the cutting fluid. Complete all marked location.
  7. Replace the drill bit with the corresponding tap bit shown in table.
  8. Apply cutting fluid on the tap. Tapping is to be done at a slower speed then drilling. Start at a slow speed then increase the speed once the tap catches a couple of threads.
  9. Reverse the direction of the drill to remove the tap remembering to carefully keep the tap bit straight.
