Overview
The Starrett S5 127mm hole saw is a high-performance carbide-tipped cutting tool designed for drilling precise holes in metal workpieces. Built with hardened cutting edges and a tough alloy steel body, this saw combines proven Starrett engineering with carbide-enhanced durability. Ideal for maintenance, fabrication, and production environments where reliability and cutting speed matter.
Key Features
- Carbide-tipped teeth for enhanced heat and wear resistance
- Hardened steel construction with bonded alloy body
- Suitable for ferrous metals, stainless steel, cast iron, and non-ferrous alloys
- Fast, smooth cutting action with efficient chip clearance
- Reduced torque and minimal snagging on initial contact
- Bonded construction reduces risk of tooth shattering
