A solid carbide drill bit with internal coolant and HRC 55 hardness is a high-performance tool for CNC machining that is designed for drilling through hard metals. Key features include its high hardness (HRC 55) for durability, solid carbide composition for wear resistance, and internal coolant channels that cool the cutting tip and flush away chips, allowing for high-speed drilling.
Key features and specifications
- HRC 55: This refers to the hardness rating of the drill bit, indicating it is designed to withstand high temperatures and pressures, making it ideal for working with hard materials like stainless steel, alloy steel, and gray cast iron.
- Solid Carbide: Made from a tungsten carbide composite, this drill bit offers superior hardness, wear resistance, and rigidity compared to high-speed steel bits.
- Internal Coolant: The drill has built-in channels that deliver coolant directly to the cutting point. This cools the bit, reduces heat build-up, extends its lifespan, and helps flush chips out of the hole.
- CNC Specific: These bits are designed for use in CNC machining centers, which provide the high rigidity and precise control needed to operate them effectively and safely. They are not for use with manual or standard power drills.
- Precision and Performance: They feature high-precision grinding for accurate hole creation and ground flutes for efficient chip removal, which increases accuracy and productivity.
- Drilling Lengths: They often come in various lengths, indicated as a multiple of the drill’s diameter (e.g., 3D, 5D, 7D), which determines the depth of the hole that can be drilled.
