Needle are meant for piercing things. So, the pointed tips allows the needle to exert high pressure on the surface to be pierced.

We know,

Pressure = Force/Area

So, for small surface area, ie. For pointed tips small force can produce large pressure.

Thus, pointed tips of needle help piercing surfaces easy.
