Starrett Bi-Metal Deep Cut Hole Saw Cutting Depth

The Starrett Bi-Metal Deep Cut Hole Saw line is built for heavy-duty hole cutting in metal, steel and wood. Each hole saw has a deep cup, so it can cut thicker material in a single pass. That cuts down on repeated passes and re-drilling. Use these saws with handheld drills, fixed drills and drill presses.

Key Features:

• Bi-metal construction: Hardened, heat-resistant, positive-rake high-speed steel (HSS) teeth are paired with a tough alloy body and cup. The saw resists shattering and holds up in demanding work.
• Aggressive cutting: The teeth penetrate material quickly and clear chips and swarf well. You may not need a separate constant-pitch or variable-pitch hole saw.
• Dual-pitch tooth design: The variable tooth spacing cuts a wide range of materials and thicknesses. It cuts smoothly with little tendency to bite or snag in thinner gauge material.
• Deep cutting capacity: The extra cup depth suits thicker wood, heavy-wall tube and metal thicker than 1/8 inch (3 mm).
• Multi-material versatility: It cuts wood, steel, stainless steel, cast iron and plastics, which suits plumbing, electrical, HVAC, fabrication and general construction work.

Starrett has made precision tools and cutting products for generations. These bi-metal hole saws are a durable choice for professionals and serious DIYers. For best results in metal, use cutting oil or lubricant, keep the feed pressure steady, and use a pilot bit to start the cut.
