RUKO KEB-HSS-TiAlN Ø39,0 mm jadrový vrták, 30 mm hĺbka rezu, Weldon 19 stopka

On steel construction sites and in metalworking shops, the RUKO KEB-HSS-TiAlN Ø39.0 mm annular cutter drills precise holes through structural steel, plates, and profiles. The TiAlN coating reduces friction and withstands high temperatures, making it suitable for demanding drilling tasks.

Key specifications

• Cutting diameter: 39.0 mm
• Cutting depth: 30 mm
• Material: High-speed steel (HSS)
• Coating: TiAlN (Titanium Aluminum Nitride)
• Shank type: Weldon 19 (3/4 inch)

Why choose it

The TiAlN coating increases tool life by up to 100% compared to uncoated HSS cutters. It offers excellent wear resistance and heat resistance up to 800°C, allowing higher cutting speeds and improved productivity. The annular cutter design removes only a ring of material, leaving a solid core that is automatically ejected, which reduces power consumption and machining time.

Ideal use cases

• Drilling large-diameter holes in steel plates and profiles
• Use with magnetic drilling machines or pillar drills with appropriate adapter
• Working with steel, stainless steel, cast iron, and non-ferrous metals

Good to know

The cutter has an overall length of approximately 65 mm and features optimized chip evacuation for efficient drilling. It is compatible with Weldon 19 shank tool holders, a common standard for annular cutters.
