Bosch Hole Saw for Brass/Cast Iron/NF Metal/Steel/SS 30mm 20mm

The Special for Sheet Metal Hole Saw offers durability while cutting holes through metal. Made of bi-metal HSS (high-speed steel) containing 8% cobalt alloy, this hole saw has less risk of tooth breakage and higher heat resistance for extreme resilience and a long product lifetime. The configuration of the teeth on the Vario tooth strip is ideal for sawing through thin material with reduced wear on the cutting edge. Furthermore, a depth-stop feature prevents breakthroughs to protect the work surface. Use this hole saw when cutting through sheet metal with a thickness of less than 5 mm, such as mild steel and stainless steel. The Special for Sheet Metal Hole Saw features Bosch's unique power-change adapter with the fastest arbour system on the market. It allows for locking and unlocking the hole saw and pilot drills in one click.
