Grooving turnover knives are a type of cutting tool that is commonly used in the woodworking industry for making grooves or channels in wood. They are designed to be used with a grooving machine or a shaper, and are available in a variety of sizes and shapes to suit different applications. In this article, we will explore the features and benefits of grooving turnover knives.

Features of Grooving Turnover Knives:

1. Material:

Grooving turnover knives are made from a variety of materials, including high-speed steel (HSS), carbide, and diamond. HSS knives are the most affordable but are not as durable as carbide or diamond. Carbide knives are the most popular due to their durability and versatility. They can be used for a wide range of applications and are suitable for both handheld and table-mounted routers. Diamond knives are the most expensive but are the most durable and can be used for cutting hard materials like glass and stone.Grooving Turnover Knives

2. Shape:

Grooving turnover knives come in a variety of shapes, each with its own specific use. Some of the most common shapes include:

  • – Straight Knives: These knives have a straight cutting edge and are used for making straight grooves or channels in wood.
  • – V-Groove Knives: These knives have a V-shaped cutting edge and are used to create decorative grooves in wood.
  • – Cove Knives: These knives have a concave cutting edge and are used to create decorative edges on wood.
  • – Chamfer Knives: These knives have an angled cutting edge and are used to create beveled edges on wood.
  • – Dado Knives: These knives have two parallel cutting edges and are used to create wide grooves or channels in wood.

3. Size:

Grooving turnover knives come in a range of sizes, and it’s important to choose the right size for the job. The size of the knife will depend on the width and depth of the groove that you need to make.

4. Cutting Edge:

Grooving turnover knives have a sharp cutting edge that is designed to cut through wood with precision and accuracy. The cutting edge is made from a small piece of carbide or diamond that is brazed onto the body of the knife.

Benefits of Grooving Turnover Knives:

  • 1. Versatility: Grooving turnover knives are suitable for a wide range of applications, including creating decorative grooves, making channels for electrical wiring, and cutting dadoes for joints.
  • 2. Precision: Grooving turnover knives are designed to cut through wood with precision and accuracy. This allows for clean, straight cuts that are free of splinters and tear-out.
  • 3. Durability: Carbide and diamond grooving turnover knives are extremely durable and can withstand a lot of wear and tear. This means that they can be used for longer periods of time without needing to be sharpened or replaced.
  • 4. Easy Replacement: When a grooving turnover knife becomes dull or damaged, it can be easily replaced without having to replacethe entire cutter head or shaper. This makes maintenance and repairs more cost-effective and less time-consuming.
  • 5. Improved Efficiency: Grooving turnover knives can help to improve efficiency in the woodworking shop by allowing for faster and more precise cuts. This can save time and increase productivity, ultimately leading to greater profitability.
  • 6. Better Surface Finish: Because grooving turnover knives are designed to make clean and precise cuts, they can produce a smoother and more precise finish on the wood. This is especially important for finishing work, where a high-quality surface finish is essential.
  • 7. Safety: Grooving turnover knives are designed with safety in mind. They are typically made with a protective coating to help prevent kickback and other safety hazards. Additionally, they are designed to be used with specific machinery that has safety features built-in.

In conclusion, grooving turnover knives are a versatile and valuable tool in the woodworking industry. They are available in a range of sizes and shapes, and can be made from a variety of materials to suit different applications. Their precision, durability, and ease of replacement make them a popular choice for woodworkers who need to make grooves or channels in wood. By choosing the right grooving turnover knife for the job and following proper safety protocols, woodworkers can achieve clean and precise cuts that will improve efficiency, increase productivity, and ultimately lead to greater profitability.
