Specification
Brand : HARFINGTON
BulletPoint1 : Size - Cutting edge diameter: 18.5mm, shank diameter: 1/2 inch, flute length: 3.2 inch, total length: 6 inch, split point: 118°
BulletPoint2 : Material - 4341 high-speed steel maintains excellent corrosion resistance and high strength, enabling effective drilling of medium-to-high hardness metals. The nitriding black actively resists oxidation and corrosion to extend drill bit durability.
BulletPoint3 : Feature - With their sharper 118° 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.
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. For larger holes, a small guide hole should be drilled first to ensure precision.
BulletPoint6 : Drilling Application: Ideal for drilling steel, copper, aluminum, brass, oak, maple, MDF, pine, PVC, polycarbonate, acrylic, ABS, nylon and composite materials

1. 4341 high-speed steel maintains excellent corrosion resistance and high strength, enabling effective drilling of medium-to-high hardness metals. The nitriding black actively resists oxidation and corrosion to extend drill bit durability.

2. With their sharper 118° 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. Suitable for soft metal and woodworking projects, widely used in daily operations such as home maintenance, suitable for processing medium hardness materials, such as copper, aluminum, iron, plastic, and wood

4. About the relationship between the bit and the speed, larger bits need lower RPM, smaller bits require higher RPM, and harder materials require lower RPM for better cutting performance and longer drill life.

5. When using a Reduced Shank 3-Flat drill bit, it's crucial to maintain a 90-degree vertical angle for precision and accuracy. Additionally, water or coolant should be used to reduce temperature and prevent overheating. This helps ensure optimal performance and extends the lifespan of the drill bit.
