Fein TCT Ultra 50 Core Drill Bit With 3/4" Weldon Holder 46mm | 63127310010

Fein 63127310010 TCT Ultra 50 core drill bit, 46mm, 3/4" Weldon holder

Fein 63127310010 is a TCT core drill bit designed for fast, accurate hole-making in metal, using a 3/4" Weldon holder for secure fitment on compatible magnetic drilling machines and core drilling setups. The TC Ultra 50 range is built for tough workshop and site use, helping reduce tool changes on repeat drilling tasks.

With a 46mm diameter and 50mm cutting depth, this model is suited to producing clean annular holes while maintaining smooth cutting action, thanks to its multi-flute design and chip evacuation geometry.

Key Features

• TCT (carbide-tipped) cutting edges: Designed for high wear resistance and consistent cutting in demanding metal drilling applications.
• TC Ultra 50 design: Built for continuous use with strong durability for repetitive hole-making work.
• Conical flute geometry: Helps promote efficient chip removal to support smoother drilling and improved productivity.
• 3-flute cutting design: Aims to reduce chatter for controlled cutting and more accurate results.
• High heat resistance: Suitable for heavy-duty drilling conditions with heat resistance up to 800°C.
• 3/4" Weldon holder: Common industrial shank type for secure drive and reliable torque transfer on compatible machines.
