RUKO KEB-HSS-TiAlN-Mod.55-48,0 mm jadrový vrták

Professional machinists and metal fabricators rely on the RUKO KEB-HSS-TiAlN Mod.55 core drill bit for precise, large-diameter holes in steel, stainless steel, cast iron, and non-ferrous metals. Its 48 mm cutting diameter and 30 mm cutting depth make it suitable for structural steelwork, pipe fitting, and heavy equipment maintenance where accurate, clean bores are essential.

Key specifications

• Cutting diameter: 48 mm
• Cutting depth: 30 mm
• Material: High-speed steel (HSS)
• Coating: Titanium Aluminum Nitride (TiAlN)
• Shank type: Weldon shank, 19 mm (3/4 inch)
• Series: Mod. 55

Why choose it

The TiAlN coating provides high hardness, wear resistance, and heat resistance, reducing friction and extending tool life. The ground manufacturing process ensures precise cutting edges for accurate holes. The Weldon shank allows secure clamping in magnetic drilling machines, preventing slippage during heavy-duty operations.

Ideal use cases

• Drilling large holes in steel plates and beams
• Creating openings for pipes and conduits in stainless steel
• Maintenance and repair of heavy machinery
• Fabrication work in metal workshops

Good to know

The drill bit can be used with or without cutting fluid, depending on the application. It is compatible with pilot pins for guided starts. The dark grey/bronze appearance is characteristic of the TiAlN coating.
