Dolphin 90° 3 Fluted Counter Sink TIN Coated

The "Dolphin 90° 3 Fluted Countersink TIN Coated" is a specific type of cutting tool used for countersinking operations. Here's what each component of the description generally means: 1. **90°**: This indicates the angle of the countersink. A 90-degree countersink creates a countersunk hole with a 90-degree angle between the surface of the workpiece and the tapered surface of the countersink. 2. **3 Fluted**: This refers to the number of flutes or cutting edges on the countersink. In this case, there are three flutes, which help in the efficient removal of material and provide stability during cutting. 3. **Countersink**: A countersink is a tool used to create a conical hole in a workpiece, allowing the head of a screw to sit flush with or below the surface of the workpiece. 4. **TIN Coated**: TIN stands for Titanium Nitride, which is a hard ceramic material often used as a coating on cutting tools. TIN coating improves the tool's wear resistance, reduces friction, and helps in extending tool life. In this case, the countersink is coated with TIN for enhanced performance and durability. Overall, the Dolphin 90° 3 Fluted Countersink TIN Coated is a specialized cutting tool designed for creating countersunk holes at a 90-degree angle with improved wear resistance and durability due to its TIN coating. It is commonly used in metalworking and woodworking applications where countersunk holes are required for fastening components.
