Fein 63134270051 HSS Nova 25 core drill bit, 27mm & 25mm cutting depth (3/4" Weldon)

Fein 63134270051 is an HSS Nova 25 core drill bit designed for fast, clean holemaking in metal when used with a compatible mag drill or core drilling machine. With a 3/4" Weldon shank and a 27mm cutting diameter, it’s a practical choice for fabricators and maintenance teams who want reliable, repeatable results on site or in the workshop.

This 63134270051 core bit uses an annular cutting style to remove only the material around the perimeter of the hole, helping to reduce effort compared with drilling the full diameter. The 25mm cutting depth suits common structural and platework tasks where consistent hole size matters.
