the Advantages of TCT annular cutter with weldon shank
Patented Triple-Edge Cutting Geometry
Unlike standard cutters that use a single-cutting edge, CHTOOLS features a unique Inner, Middle, and Outer layered edge design. This configuration fragments metal chips into smaller pieces, ensuring effortless chip removal and preventing "slug sticking" or tool binding.
01
Full-Process CNC Precision Manufacturing
Every annular cutter is manufactured using fully automated CNC grinding. This guarantees perfect concentricity (minimal runout) and a superior Ra 0.4 surface finish, resulting in holes that are cleaner, more accurate, and require no secondary deburring.
02
Premium Micro-Grain Tungsten Carbide (TCT)
We select only high-grade, ultra-fine micro-grain carbide tips. These tips offer exceptional hardness and thermal stability, allowing you to drill through hardened steel and stainless steel with a tool life 30% longer than the industry average.

Applicable industry
Steel structure, bridge engineering, shipbuilding industry, oil rig, railway construction, machinery manufacturing, electric power, etc.
TCT annular cutter with weldon shank 's FAQ
Q:1.What is the primary difference between TCT and HSS annular cutters?
+
-
A: TCT (Tungsten Carbide Tipped) cutters feature carbide inserts that are significantly harder than HSS (High-Speed Steel). TCT bits can operate at higher RPMs with less heat buildup, making them essential for drilling thick plates (>20mm) and hard materials like stainless steel.
Q: 2. What is a TCT annular cutter?
+
-
A: TCT annular cutters are designed with spiral flutes and geometrically arranged tungsten carbide tips for efficient cutting at high speeds with less heat resistance.
Q: 3.How does the layered geometry improve performance?
+
-
A: The layered design splits the cutting load across three distinct edges. This reduces the cutting force required from the machine, lowers vibrations, and ensures that chips are broken down for smoother ejection through the spiral flutes.
Q: 4. What is the difference between HSS and TCT annular cutters?
+
-
A: HSS cost less than their TCT counterpart but have a significantly shorter lifespan and operate at a slower speed. They are a popular choice of cutter for those smaller, quicker projects.
Q: 5. What does "TCT" stand for in industrial drilling?
+
-
A: TCT stands for Tungsten Carbide Tipped. It refers to the specialized grade of cemented carbide used at the cutting edge to provide maximum wear resistance and thermal stability in heavy-duty drilling applications.
