Cle-Line 25098 79 mm Hole Saw

The Cle-Line 25098 is a bi-metal hole saw with a 79 mm cutting diameter and M3 designation. It is built for electricians, plumbers and maintenance technicians who need clean holes in sheet metal, steel plate or plastic. The bi-metal construction resists tooth breakage and extends cutting life on tough materials. This accessory fits standard arbors for use with hand-held drills or drill presses.

Check Arbor Compatibility And Material Thickness

Verify that your existing arbor accepts the M3 mounting configuration before ordering. Confirm the workpiece thickness does not exceed the saw’s cutting depth capacity. Ensure your drill delivers sufficient torque at low speed for 79 mm diameter cutting. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Fits Standard Arbors And Frees Pilot Bit Changes

The hole saw mounts on common quick-change arbors so it integrates with current drill setups without new hardware. Its bi-metal teeth reduce the need for frequent sharpening or saw swaps during repetitive jobs. The design clears chips efficiently, keeping the cut straight and reducing binding. Use with cutting fluid to further extend tool life.

Questions about this item

Does the Cle-Line 25098 hole saw include an arbor or pilot bit, or must they be purchased separately?

The Cle-Line 25098 79 mm bi-metal hole saw is sold as the saw blade only; a compatible M3-thread arbor and pilot bit are not included and must be bought separately.

Which size should I choose between the 3-1/8 inch and 79 mm listings for the Cle-Line 1887?

Both figures describe the same cutting diameter; 3-1/8 inch and 79 mm are equivalent, so select the single Cle-Line 25098 model that matches the hole size you need.

What does the 79 mm diameter mean when the Cle-Line 25098 is mounted in a drill?

When chucked in a drill, the Cle-Line 25098 cuts a clean 79 mm (3-1/8 in.) hole through metal, wood or plastic, limited only by the saw’s cutting depth and the arbor length you pair with it.
