• Premium quality steel
• 4/6 TPI variable tooth pattern
• 38mm (1 1/2”) cutting depth
• Holesaws/arbors fully interchangeable with most other brands

Applications

Sheet metal, cast iron, Aluminium, wood, plywood, plastics and pipe.

Recommendations

Ensure the recommended speed is used for different diameters of holesaw.

Use the correct cutting fluid when making holes in metal, other than cast iron which should be cut dry.

Use correct level of pressure when hole cutting. Too much or too little can damage cutting edges.

Pilot drills should be correctly assembled to ensure they do not extend beyond cutting teeth further than the material thickness being cut.
