Specification
Brand : HARFINGTON
BulletPoint1 : SIZE: Cutting edge diameter: 14mm, shank diameter: 1/2", flute length: 75mm/2.95 inch, total length: 150mm/5.91 inch, package content: 1Pcs x Reduced Shank Drill Bit
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 standard 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 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 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,the nitriding black finish enhances the drill bit's wear and corrosion resistance, thereby extending the drill bits' lifespan.

2. The 118° Standard Point tip angle is the traditional standard angle, enabling quick penetration into materials and broad applicability, suitable for wood, plastic soft metal, and other materials drilling, widely used in daily operation, more appropriate for home and light industry use, simple operation, strong adaptability.

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 large drill bit, it’s best to start by drilling smaller holes. This makes it easier to create larger holes accurately.When using a reduced shank 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.
