Fein TCT Ultra 50 Core Drill Bit With 3/4" Weldon Holder 57mm | 63127321010

Fein 63127321010 TCT Ultra 50 Core Drill Bit (57mm) with 3/4" Weldon Holder

Fein 63127321010 is a TCT (carbide-tipped) core drill bit designed for fast, accurate metal core drilling where long service life and clean cutting matter. With a 3/4" Weldon holder and 50mm cutting depth, it’s a practical choice for workshop and site work using compatible magnetic drilling machines.

This 57mm TCT Ultra 50 core drill bit uses a conical flute to support efficient chip removal and a multi-edge cutting design to help reduce chatter for smoother holes. The HM Ultra 50 range is built for continuous use and high heat resistance.

Key Features

• Carbide-tipped (HM) cutting geometry: Designed for tough, repetitive metal drilling with excellent wear resistance.
• Heat resistance up to 800°C: Built to cope with demanding cutting conditions during continuous use.
• 50mm cutting depth: Suitable for producing deeper annular holes in plate and structural steel without constant re-positioning.
• 3/4" Weldon holder: Common shank standard for secure mounting on compatible magnetic drilling machines and arbors.
• Conical flute design: Helps move swarf away from the cut for smoother progress and reduced clogging.
• Multi-edge cutting design: Aims to deliver stable, chatter-reduced cutting for cleaner, more accurate results.
