Bi-Metal Fast Cut Hole Saw 1-3/8

This Starrett hole saw is built for electricians, plumbers and metalworkers who need clean 35 mm holes in sheet metal, pipe or plastic. The bi-metal construction resists tooth breakage and stays sharp longer than standard carbon steel cutters. It fits standard arbors for use in handheld drills or drill presses. The tool is sold new and ready for immediate job-site use.

Cutting limits of the hole saw format

The 35 mm diameter fixes the maximum hole size; larger openings require a different saw or a step-drill approach. Cutting depth is limited by the saw cup height, so thick-walled pipe or plate may need multiple passes or a longer pilot bit. The saw is not impact rated, so it must be run in a rotary-only drill chuck. Hardened steels or abrasive composites will dull the teeth faster than mild steel or aluminium.

Installation and common issues

Mount the saw on a matching arbor, tighten the set screw and engage the pilot bit before starting the cut. Use cutting oil on metal to reduce heat and extend tooth life. The most frequent problems are the arbor loosening under vibration, the pilot bit walking on smooth surfaces and teeth chipping if the feed pressure is too aggressive. Clearing chips regularly prevents binding and overheating.

Questions about this item

Should I choose the 35 mm or 1-3/8 inch marking for my project?

Both markings refer to the same cutting diameter; 35 mm is the metric equivalent of 1-3/8 inches, so select whichever unit your drawings use.

What does the 35 mm diameter mean when the saw is mounted in a drill?

The saw will cut a clean 35 mm hole in sheet metal, wood or plastic at the rated speed of the arbor.

What shank interface does this hole saw use and what does it limit?

It fits a standard threaded arbor, which caps the maximum cutting depth to the saw’s cup height.
