Starrett DCH0034 Deep Cut Bi-Metal Hole Saw 19mm

This Dual-Performance Bi-Metal Hole Saw description combines two high-efficiency cutting tools designed for metal and mixed-material applications. Both models use a bi-metal construction with enhanced tooth materials to improve heat resistance and wear life, delivering aggressive material penetration and kerf clearance. The designs emphasize smooth, fast cutting with features that reduce binding and promote clean edges. One variant is optimized for faster cuts and thinner metal sections, while the other provides deeper cutting depth for thicker tubes and solid materials. The available sizes cover a wide range of interior and exterior work, including wood, plastic, plaster, and metal sheeting, making them suitable for plumbing, electrical, and general DIY or professional projects. Note that certain models specify depth capabilities and inclusions to match different project needs.
