MAKITA D-21624 Bi-Metal Hole Saw 19 mm (3/4")

MAKITA D-21624 BIM Hole Saw 19 mm (3/4")
Makita hole saw SKU D-21624 is a hole saw in the Bi-Metal (BIM) Hole Saw lineup, recognized for durability and operational safety. The Bi-Metal design combines the best qualities of two materials: Saw Teeth (HSS): Uses High-Speed Steel (HSS) with ultra-high hardness to easily cut through metal and hard materials while maintaining sharpness. Body (Spring Steel): Uses spring steel that offers high flexibility, which helps prevent the hole saw body from shattering upon impact or binding, making it safer for operators than standard HSS hole saws. The 19 mm or 3/4 inch hole saw is a compact size ideal for drilling small openings, especially in electrical and plumbing jobs requiring high precision.
