MAGBIT MAG624 (624.4816) 3‑Inch Bi‑Metal Hole Saw — 1‑3/4‑Inch Cutting Depth

Overview

The MAGBIT MAG624 is a high-performance 3‑inch bi‑metal hole saw designed for demanding professions like electrical work and general construction. Its robust build and variable pitch design enable clean, rapid cuts through wood, thin metals, and plastic, making it a reliable tool for repeated use in structural framing and conduit installations.

Key Specifications

• Diameter: 3 inches

• Cutting Depth: 1‑3/4 inches — powerful enough to slice through standard 2×4 studs in a single pass

• Material: Steel alloy body with cobalt steel teeth for enhanced durability and long-lasting performance

• Tooth Design: 4/6 TPI (teeth per inch) with variable pitch for reduced vibration and faster cut rates

• Backing Plate: Heavy-duty 3/16-inch thick for structural integrity and resistance to warping

• Chip Removal Feature: Side cutouts, large gullets, and deep slot design allow for efficient debris ejection and heat dissipation — keeping the saw running cooler and sharper

Benefits

• Efficient and Deep Cutting: The extended 1‑3/4‑inch depth makes it ideal for drilling through thick framing, eliminating the need for flipping or repositioning. This is particularly useful when making holes for wiring runs through wall studs or floor joists.

• Durability You Can Trust: With a rugged steel alloy body, cobalt-reinforced teeth, and solid backing, this hole saw is built for prolonged heavy use.

• Cleaner, Faster Cuts: Variable tooth pitch and smart design features minimize vibration and burrs, delivering a smoother cutting experience.

• Improved Chip Ejection: The large gullets and side cutouts ensure that shavings are cleared rapidly, maintaining cutting efficiency and reducing heat build-up.
