Fein TCT Ultra 35 Core Drill Bit With 3/4" Weldon Holder 13mm | 63127715010

Fein 63127715010 HM Ultra 35 annular core drill bit (13mm) with 3/4" Weldon shank

Fein 63127715010 is a carbide-tipped annular core drill bit designed for fast, accurate hole cutting in metal, with a 3/4" Weldon shank for use with compatible magnetic drills and core drilling systems. It’s a practical choice for workshop and fabrication work where clean holes and reduced tool changes matter.

Part of the HM Ultra 35 range, this 13mm core drill uses a conical flute for efficient chip removal and a 3-flute design for smooth, controlled cutting. The design is intended for continuous use, helping maintain performance during repetitive drilling tasks.

Key Features

• Carbide-tipped cutting edges: Built for wear resistance and consistent performance when drilling metal.
• HM Ultra 35 range design: Intended for continuous use in demanding workshop and fabrication environments.
