Hole Saws - Carbide Multi-Purpose MPH

Starrett MPH carbide multi-purpose hole saws are made for the tradesperson who moves between materials on the same job. They cut confidently across wood, plastic, thin metal and masonry board without changing tools. Tungsten carbide teeth give a long service life, even when you switch between softer materials and more abrasive ones like masonry board. With diameters from 19mm to 159mm, the MPH range covers common pipe and cable holes, downlight openings and larger service penetrations for general trade use. How to choose: choose MPH when you do not know exactly what you will cut, or when one job involves several materials. If you work mainly in abrasive or nail-embedded materials, compare it with the CT range; for deep holes in thick abrasive material, see CTD. Usage tips: adjust the drill speed to the material, running slower in metal and larger diameters, and clear the core between holes. A sharp pilot drill keeps the hole saw accurately centred.
