Rotabroach HSS 26mm Mag Drill Bits, 8 Flutes

The Rotabroach RAP260 is a 26 mm diameter annular cutter designed for use with magnetic drilling machines, optimised for cutting through mild and structural steel up to ~700–900 N/mm². Its M2 heat-treated high-speed steel body, precise shank tolerance, and aggressive cutting geometry reduce vibration and wear. With a cutting depth of ~25 mm and U-groove flutes for efficient chip evacuation, this magnetic drill bit (mag drill bit) is suited for fabrication, construction, rail, and industrial applications. Supplied through Enrgtech, the RAP260 balances speed, precision, and tool durability in demanding drilling tasks.

What Makes the Rotabroach RAP260 Mag Drill Bit Stand Out?

The RAP260 magnetic drill bit stands out by combining heat-treated M2 alloy, tight shank tolerances, optimised 20° clearance angles, and deeper-wall strength. This annular cutter delivers enhanced cutting stability, reduced vibration, and extended tool life.

Functional Highlights of the Product:

• Diameter: 26 mm
• Cutting depth: ~25 mm
• Material: Heat-treated M2 (HSS)
• Clearance angle: 20° (optimised for stability)
• Wall thickness: ~4.6 mm for greater strength
• U-groove flutes for efficient chip evacuation
• Tight shank tolerance for concentricity and reduced breakage
• Suitable for structural steel and general fabrication use (≤ 700 N/mm²).
