Starrett SM19 Carbide Tipped Hole Saw

The Starrett SM19 is a carbide tipped hole saw with a 19mm cutting diameter. It belongs to the power and pneumatic accessories category for automotive and trade use. The tool is supplied new and ready for immediate workshop deployment. Professional users select it for clean cuts in demanding materials.

Carbide tooth geometry and cutting depth

Carbide tips maintain sharpness longer than bi-metal equivalents when cutting stainless steel, cast iron or abrasive composites. The cutting depth is fixed by the saw body and cannot be extended for thicker workpieces. Users must clear chips frequently to prevent binding and overheating during deep cuts.

Arbor mounting and common fitting issues

The hole saw mounts on a standard arbor with a pilot drill for centering. The pilot drill must project far enough to engage before the teeth contact the workpiece. Misalignment or a worn pilot drill causes wandering holes and premature tooth damage.
