Specification
Brand : HARFINGTON
BulletPoint1 : Size - Cutting edge diameter: 9/16", shank diameter: 1/2", total length: 152.4mm/6inch, flute length: 76.2mm/3inch, Standard Point: 118°
BulletPoint2 : Material - The 4241 high-speed steel has improved toughness and provides hardness and wear resistance. It achieves a favorable balance between cost-effectiveness and practicality, it suitable for small equipment and light-duty machining. and the nitriding black finish enhances the drill bit's wear and corrosion resistance
BulletPoint3 : Feature - The 118° standard point tip angle is the traditional angle, enabling quick penetration into materials and broad applicability, making them the preferred choice for general metal and wood drilling, as well as common tasks like DIY, woodworking, and home repairs.
BulletPoint4 : Application - Suitable for soft metal and woodworking projects, widely used in daily operations such as home maintenance, suitable for processing medium hardness materials, such as thin stainless steel, copper, aluminum, iron, plastic, and wood
BulletPoint5 : Note - Ensure a 90-degree vertical angle is maintained between the drill and the material. When using a large size of drill bit, it’s best to start by drilling smaller holes. This makes it easier to create larger holes accurately

1. The 4241 high-speed steel material provides hardness and wear resistance. Furthermore, the nitriding black surface treatment enhances both wear and corrosion resistance, significantly extending the drill bit's lifespan.

2. With their sharper 118° standard point angle, twist drills can quickly and efficiently drill into materials, making them the preferred choice for general metal and wood drilling, as well as common tasks like DIY, woodworking, and home repairs.

3. These drill bits are suitable for soft metals and woodworking projects, making them popular for DIY tasks and home maintenance. They are well-suited for processing medium to low-hardness metals, such as common steel, aluminum alloy, and copper, as well as for drilling wood and plastic materials.

4. The relationship between the drill bit and speed is critical: larger bits require lower RPM, while smaller bits need higher RPM. Additionally, harder materials demand lower RPM for better cutting performance and extended drill bit life.

5. For optimal performance with a reduced shank drill bit, ensure a 90-degree vertical standard point angle is maintained between the drill and the material. For larger holes, a small guide hole should be drilled first to ensure precision.. Caution: This drill bit is unsuitable for stainless steel.
