Rotabroach HSS 12mm Mag Drill Bits, 4 Flutes

The Rotabroach RAP120 is a high-performance 12mm magnetic drill bit designed for precision hole-cutting in ferrous metals. Crafted from premium M2 high-speed steel, this short-series annular cutter features a 25mm cutting depth and a standard 19mm Weldon shank. Its unique tooth geometry and U-shaped recesses optimise chip removal and reduce friction, enabling faster, more accurate drilling than traditional twist bits. This tool is a staple for professionals seeking durability and a fine-finish hole.

Benefits of Using the Product

The Rotabroach RAP120 drill bit reduces physical effort and machine wear by requiring significantly less power to penetrate tough metal surfaces.

• Delivers superior accuracy and a burr-free finish, eliminating the need for secondary reaming.
• Increases productivity by cutting holes much faster than conventional HSS twist drills.
• Extends tool life through advanced heat treatment that resists brittleness and breakage.

Key Features & Suitable Environments

• Special Features:
• Enhanced Wall Thickness: A 4.6mm wall provides extra strength to withstand high-pressure drilling tasks.
• Precision Shank Tolerance: Tighter tolerances reduce vibration and concentricity issues during high-speed rotation.
• U-Shaped Recesses: Specialised flute design ensures efficient swarf evacuation and prevents clogging.
• Step-Hardened Teeth: Features a hardness of HRC65-67 for the teeth while maintaining a flexible shank.
• Typical Applications:
• General engineering, steel fabrication, and bridge construction.
• Maintenance and repair of railway tracks and rolling stock.
