Fein 63134530051 HSS Nova 25 core drill bit – 53mm, 3/4" Weldon, 25mm cutting depth

Fein 63134530051 is an HSS core drill bit designed for fast, accurate holemaking in metal when used with a compatible 3/4" Weldon (annular cutter) holder. With a 53mm cutting diameter and 25mm cutting depth, it’s a practical choice for installers and fabricators who need clean, controlled holes with reduced material removal compared with twist drills.

Part of the Fein Nova 25 range, this 53mm core bit is supplied as a single cutter and is suited to mag drills and core drilling machines that accept 3/4" Weldon shank tooling.

Key Features

• HSS Nova 25 design: High-speed steel core bit construction for metal drilling applications.
• 53mm cutting diameter: Ideal for larger clearance holes where a standard twist drill would be slow and material-intensive.
• 25mm cutting depth: Suitable for typical plate and section drilling tasks within the cutter’s depth of cut.
• 3/4" Weldon shank: Industrial-standard fitting for use with compatible core drilling machines and magnetic drills.
• Metric sizing: Clear metric dimensions for straightforward selection and repeatable results.
