Annular Cutters for Metal Drilling | TCT & HSS Types
Annular cutters, also known as core drills, are designed for efficient and precise hole cutting in metal. Compared to traditional hss drill bits, annular cutters remove only the material at the edge of the hole, resulting in faster drilling, less energy consumption, and cleaner cuts.
As a professional manufacturer and supplier, we offer a full range of annular cutters in both TCT (Tungsten Carbide Tipped) and HSS (High-Speed Steel) types to meet different industrial and construction needs.
Our annular cutters are widely used with magnetic drilling machines in steel fabrication, bridge construction, shipbuilding, railway engineering, heavy equipment manufacturing, and industrial maintenance. Available in various cutting depths and diameters, they deliver excellent hole accuracy, long service life, and reliable performance for both on-site and workshop applications.
Types of Annular Cutters
TCT Annular Cutters
TCT annular cutters are designed for high-performance and heavy-duty applications. With carbide-tipped cutting edges, they provide excellent durability and are suitable for cutting hard materials.
- Ideal for steel plates, stainless steel, and alloy materials
- High wear resistance and longer lifespan
- Suitable for industrial and continuous use
- Available with optional titanium coating
HSS Annular Cutters
HSS annular cutters are a cost-effective solution for general-purpose metal drilling. They are widely used for softer materials and standard applications.
- Suitable for mild steel and general metal
- Lower cost compared to TCT cutters
- Easy to resharpen and maintain
- Ideal for light to medium-duty work
Applications
Annular cutters are widely used in:
- Steel structure fabrication
- Railway and bridge construction

FAQ
What is the difference between TCT and HSS annular cutters?
TCT annular cutters use carbide tips and are more durable, making them suitable for hard materials. HSS cutters are more economical and suitable for general-purpose drilling.
Which annular cutter is better for stainless steel?
TCT annular cutters are recommended for stainless steel due to their higher hardness and wear resistance.
What machines are annular cutters used with?
Annular cutters are typically used with magnetic drills and other industrial drilling machines.
