Overview

Meet the DECKRKAT 2-Pack 7/8 inch TCT hole saw set, designed for metalworking pros and DIY enthusiasts who demand dependable, clean cuts. Each kit includes two hole saws at 22 mm diameter with a 1 inch cutting length, plus two spring-loaded pilot bits and two hex wrenches for quick bit changes. The tools arrive pre-oiled and ready for storage in a durable case, making organization part of the package.

Built for Tough Jobs

The tungsten carbide tipped cutting edges are crafted to deliver smooth, accurate holes through hard materials such as stainless steel, mild steel, copper, iron, aluminum, FRP, and various plastics. The tools feature a 3/8 inch 3-flatted shank that helps ensure a solid chuck grip across a wide range of drills, CNC machines, and handheld power tools. A note of caution: avoid concrete, stone, or tiles which can damage the cutting edges.

Kit Contents

• Two 7/8 inch hole saws with 1 inch cutting length
• Two spring-loaded pilot drill bits
• Two hex wrenches
• Rust-resistant plastic storage case

Tips for Best Results

• Start drilling with lower torque and speed when using only the pilot bit; increase as you engage the material
• Use cutting fluid to cool the edges and reduce heat buildup during extended cuts
• Keep the drill perpendicular to the workpiece and apply minimal feed pressure until the bit is seated
• Maintain steady rotation while exiting the material to prevent edge splintering

These hole saws are versatile across drills, CNC setups, and other power tools, delivering reliable performance where hard metal and robust plastics demand precision. While they excel in metalworking tasks, following the care steps—such as cleaning after use and oiling before storage—helps maintain edge quality and longevity.
