Fein 63134200051 3/4" Weldon Holder HSS Nova Core Bit - 20mm x 25mm

Fein 63134200051 HSS Nova 25 Core Drill Bit – 20mm diameter, 25mm cutting depth, 3/4" Weldon

Fein 63134200051 is an HSS Nova 25 core drill bit designed for fast, accurate hole cutting in metal when used with a 3/4" Weldon holder system. It’s a practical choice for trade users who need repeatable results for fabrication, installation and workshop drilling tasks.

With a 20mm cutting diameter and 25mm cutting depth, this HSS annular cutter helps remove less material than a traditional twist drill, supporting efficient drilling where clean, consistent holes are required. The 63134200051 uses metric sizing for straightforward selection on site.

Key Features

• HSS annular cutter design: Core drilling action removes only the material needed for the hole, helping improve efficiency compared with drilling out the full diameter.
• 3/4" Weldon shank: Industry-standard Weldon fitting for secure location in compatible holders and magnetic drilling machines.
• 20mm cutting diameter: Sized for common clearance and fixing holes in metal fabrication and installation work.
• 25mm cutting depth: Suitable for drilling through typical steel sections within the stated depth capacity.
• Metric dimensions: Clear metric sizing makes it easier to match to drawings, fixings and hole requirements.
