Here is an elaboration of the parameters of this drill:
1. Recommended drilling depth: This is the maximum depth to which it is recommended to drill with a given drill bit. This includes both the technical limitations of the tool and optimal machining results.
2. Drill tip angle: This is the angle at which the drill blades are made. This angle is crucial to the effectiveness of drilling in various materials. A proper tip angle helps minimize friction and provides better guidance for the drill bit, which translates into efficiency and precision in the drilling process.
3. 2-Cutting-Blade Drill 2-Slot*: The term "2-blade" means that the drill has two cutting blades. The number of blades affects the speed of drilling and the quality of the hole. "2-blade" suggests the presence of two counter-directional bald spots (thin elongation strips) that help evacuate chips and cool the blades.
4. Smooth cylindrical shank according to DIN 6535-HA: This is a standard cylindrical shank that meets the specified DIN 6535-HA standards. It is a cylindrical shank that provides stable clamping of the drill bit in the machine spindle. The DIN 6535-HA standard may specify specific requirements for the tolerances and quality of the cylindrical shank.
5. Solid carbide tool: Means the tool is made entirely of a hard and durable material such as carbide. Solid carbide tools are known for their strength and longevity, which translates into longer life and less need for replacement.
6. Coating on the cutting part: This is an additional layer of material covering the cutting part of a drill bit. These coatings can have various properties, such as reducing friction, increasing wear resistance, facilitating chip evacuation, or increasing tool life. The coating allows the drill bit to operate more effectively and efficiently, and to be more resistant to high loads and extreme machining conditions.
