Lenox 2-3/4 in Bi-Metal Speed Slot Hole Saw (70 mm) – Fast Cutting, Durable Design

Overview

The Lenox 2-3/4 in Bi-Metal Speed Slot Hole Saw is built for metal and wood tasks, delivering faster starts and cleaner holes. With a 70 mm diameter and T3 tooth geometry, this tool is designed to handle demanding jobs where precision and consistency matter.
