An HSS conical cutter is a specialized cutting tool made of high-speed steel (HSS) that drills clean, variable-sized holes in thin materials like sheet metal and plastics. Its conical shape allows for rapid drilling and enlarging of holes without a pilot hole, and it is designed for smooth operation with high cutting performance. HSS makes the tool durable and heat-resistant, suitable for general metalworking and fabrication applications.
Key features and characteristics
- Material: High-speed steel (HSS), known for its toughness and ability to withstand heat.
- Design: A tapered, conical shape that allows it to cut and enlarge holes as it is advanced into the material.
- Application: Ideal for drilling variable-sized holes in thin materials (e.g., sheet metal, plastic, PC boards, alloys) up to 2mm thick.
- Performance:
- Delivers clean and reliable performance.
- Requires no pilot hole, increasing efficiency.
- Offers smooth operation and a high cutting achievement.
- Specifications:
- Often features a pointed 118° angle, though other angles exist.
- Has a right-hand cutting edge.
- May include features like surface without discoloration and precision-ground diameters for accuracy.
- Benefits:
- Durable and wear-resistant due to HSS material.
- Versatile for a range of materials.
- Can be used in less rigid machining environments compared to carbide tools.
