135°Cutting tip angle Cylindrical drill handle
Compared with ordinary drill bits, it significantly reduces slipping. It is recommended to still use a center punch on smooth curved surfaces to achieve the best positioning effect.
Spiral flute optimization: chips are removed smoothly, less likely to stick, suitable for deep hole drilling.
best hard metal metric drill bits
*Drilling ordinary steel plates, angle iron, and square tubes (such as shelves, guardrails, and equipment brackets).
*For stainless steel thin plates (=2mm): must use low speed, cutting oil, and a bench drill or a stable handheld electric drill.
Detailed dimensions of torsion bar drill bits
Contains different sizes
It can be selected according to needs
The 1.5mm-6.5mm metric drill meets the needs of routine home operation, and high-quality products are also suitable for professional work operation
Dimension-coded storage boxes for easy sorting
Independent molded index slots: Each drill bit has a dedicated position, fixed firmly, never wobbling or colliding with each other, protecting the cutting edge.
Example of how to use it
Examples of incorrect usage
The drill bit does not work on the diagonal side of a hard object, which will cause it to slip and break in severe cases
Examples of correct usage
The torsion bar drill bit should be perpendicular to the item and provide the right forward pressure
Ways to improve efficiency and longevity
Adding cutting oil during use to help cool and lubricate the drill bit can improve efficiency and extend its lifespan.
