Description
Information
Drilling with burrred: Reduce the number of holes and check various cutting conditions to ensure proper tool handling
Lower forward and backward speed Use harder aluminum and wood Choose the right cutting parameters When drilling a metal with high hardness needs to be slower than a normal drill.
Wide Application
Widely used for drilling stainless steel, aluminum alloy, iron, copper, brass, hard wood, hard plastic and other metal materials.
Round shank
This universal shank is easy to use with drilling machines and bench drills, and can be used for stable drilling.
- Choosing the right lubricant is beneficial for cutting and cooling.
- Makes cutting easier, improves dimensional accuracy, and extends tool life.
Twist Drill Bit
4341 high speed steel, high hardness, good toughness, high strength, abrasion resistance, used in mechanics and machinery factories.
- Dual coating of gold titanium and black nitride improves lubricant application and makes drilling smooth.
- More durable and corrosion resistant than regular black surfaces.
- Sharp spiral flute for fast, clean and smooth cutting
