What is a TCT Hole Cutter?

A TCT (Tungsten Carbide Tipped) hole cutter is a specialized tool used for cutting precise holes in various materials, primarily metal. The carbide tips provide durability and longevity, allowing for clean and accurate cuts.

Key Features of TCT Hole Cutters

  • Size Availability: TCT hole cutters come in various sizes, typically ranging from 12mm to 100mm or more. Select a size that accommodates the material thickness and hole diameter you require.
  • Tip Design: The shape and design of the carbide tips play a significant role in performance. Look for tips designed for metal, as they will ensure cleaner cuts and longer tool life.
  • Shank Type: TCT hole cutters can come with different shank types (e.g., hex, round). Ensure compatibility with your power tools.
  • Material Compatibility: While most TCT hole cutters are versatile, check if they’re specifically designed for materials like stainless steel, mild steel, or other metals.
