Dolphin Spiral Tin Step Drill

The "Dolphin Spiral Tin Step Drill" is a type of cutting tool used for drilling holes with multiple diameters in a single operation. Here's an overview of its features: 1. **Step Drill Design**: - The step drill features a design with multiple steps or increments in diameter along the length of the drill bit. Each step allows for drilling holes with different diameters without the need for changing tools, making it efficient for various hole-sizing operations. 2. **Spiral Flutes**: - The drill bit has spiral flutes, which are the grooves or channels along the length of the drill. Spiral flutes help to evacuate chips efficiently during drilling, reducing the risk of clogging and improving the cutting performance. 3. **Tin Coating (Titanium Nitride)**: - The drill bit is coated with Tin (Titanium Nitride). This coating provides enhanced wear resistance, reduces friction during drilling, and prolongs tool life. Tin-coated step drills are suitable for drilling in a wide range of materials, including metals, plastics, and composites. 4. **Application**: - The Dolphin Spiral Tin Step Drill is suitable for drilling holes with multiple diameters in various materials. It is commonly used in applications where precise hole sizing and efficiency are required, such as in sheet metal fabrication, electrical work, plumbing, and automotive repair. 5. **Versatility**: - The step drill offers versatility, allowing users to drill holes with different diameters using a single tool. This reduces the need for multiple drill bits and saves time during the drilling process. The tin coating enhances the tool's performance and durability in various drilling applications. Overall, the Dolphin Spiral Tin Step Drill is a versatile and efficient cutting tool suitable for drilling multiple-sized holes in different materials. Its step design, spiral flutes, and tin coating make it ideal for various hole-sizing tasks in industries such as manufacturing, construction, and maintenance.
