RS PRO 102 mm Diameter HSS Bi-Metal Hole Saw for Ferrous, Wood, Plastic, Non-Ferrous Metal 215-861

RS PRO 215-861 is a 102 mm diameter bi-metal hole saw made with high-speed steel (HSS) designed for precision cutting of ferrous metals, wood, plastics, and non-ferrous metals to a cut depth of up to 32 mm. This durable drill bit features a hardened cutting edge welded firmly to an alloy steel body, enhancing toughness and reducing the likelihood of shattering under heavy load during industrial or construction work.

The 6 teeth per inch (tpi) alternate set blade design maximizes cutting efficiency, providing smooth and accurate holes that meet demanding industrial standards. Although the arbor is not included, it can be purchased separately depending on the hole saw size, with 32 to 152 mm diameter hole saws requiring a 9.5 mm arbor for mounting.

This hole saw is widely used by plumbers, electricians, and builders for drilling holes for pipe installations, wiring, drainage pipes, door hardware, vents, and light fixtures. The design ensures less effort is needed from power drills, which contributes to energy savings and preserves battery life in cordless tools.

Applications span industrial, construction, HVAC, manufacturing, and agricultural settings where reliable and precise circular hole cutting is essential. The bonded bi-metal construction balances hardness and flexibility, allowing use with power drills on various tough materials.

The RS PRO brand is recognized globally for rigorous testing and quality assurance, making this model a trusted tool in professional environments requiring durability and accuracy.
