DELIXI ELECTRIC Cross Impact Electric Hammer Drill Bit Concrete Wall Penetration Tungsten Steel Alloy Wall Drilling DLX-YSZ6 14×350

The drill bit and drill body are welded using high melting point pure copper material.

Compared to common brass welding materials with lower melting points and purity, the pure copper welding ensures higher durability.

Resistant to melting and deformation under high temperatures during drilling.

Prevents tooth loss and maintains drill integrity during use.
