JK 22MM HOLE SAW BI-METAL (7/8")

Product Description

The JK 22 mm (7/8″) Hole Saw Bi‑Metal is a high‑performance drill accessory used for cutting clean, circular holes in wood and other materials such as drywall, plastic and light metal when used with an appropriate arbor. It features bi‑metal construction with HSS‑based cutting edges that combine strength and flexibility for long life and smooth cutting. Bi‑metal hole saws are wider‑diameter alternatives to twist drill bits, making them ideal for through‑holes where regular bits can’t cut efficiently.

Key Benefits and Features

• Bi‑metal construction: High‑speed steel teeth welded to a flexible alloy body provides durability and wear resistance during repeated cutting tasks.
• HSS cutting edges: High‑speed steel helps resist heat and wear when cutting through wood, plastics and light metals.
• Efficient dust and chip removal: Slots in the saw body help clear debris as you cut for faster drilling and cleaner holes.
• Wide applicability: Suitable for wood, drywall, plastics and other softer materials (with correct speeds and arbor).
• Standard size: 22 mm (7/8″) diameter easily matches common hole requirements for cable glands, conduit feeds and pipe penetrations.

Essential Specifications
