flintronic 100mm Bi-Metal Hole Saw

The flintronic 100mm bi-metal hole saw is a versatile cutter for making neat circular holes in soft metal, wood, PVC and plastic. It combines a heat-treated M42 bimetal band and high-speed carbon steel to deliver a balance of wear resistance and clean cutting, useful when fitting handles, locks or working with pipes and furniture.

Key features

This hole saw offers a non-binding clean edge design that helps reduce burrs and keeps cuts smooth. The integrated spring ejects the cut disc automatically, saving time when you need to remove offcuts. According to the manufacturer, the teeth are formed for impact resistance to reduce loss and extend service life. A thin protective oil layer prevents corrosion during storage, but you should wipe it before use and inspect the tool condition.

Where it shines

It makes sense if you need a general purpose hole cutter that handles a mix of materials around the home or workshop. The spring ejection and non-binding edge simplify repetitive holes, and the bimetal construction aims to give reasonable longevity under typical hobbyist and trade use. Ten in mind that sustained high speed will increase wear, so keep RPM within the suggested limit.

Getting the most from it

For cleaner results use steady pressure and a suitable pilot or arbor matched to your drill press or hand drill. Start at low speed for metal and increase gently for softer materials. You’ll like it if you often cut holes for door hardware, pipe runs or cabinet fittings, where a tidy finish matters. flintronic 100mm performs best with moderate speeds and regular inspection of the teeth. 😊🛠️🔩.
