WALTHER karbidový špirálový vrták 6,8 mm, 5xD, DIN 6537 L, TiAlN povlak, vnútorné chladenie

For deep-hole drilling in demanding materials, this WALTHER solid carbide twist drill delivers precision and reliability. The 6.8 mm diameter with 5xD drilling depth and internal coolant supply ensures efficient chip evacuation and extended tool life in steel, stainless steel, cast iron, and non-ferrous metals.

Highlights

• Solid carbide (VHM) construction for high wear resistance and rigidity
• TiAlN coating reduces friction and heat, suitable for high-speed machining
• Internal coolant channels direct fluid to the cutting edge for better cooling and chip removal
• Precision ground with h7 shank tolerance for accurate hole sizing and stable clamping
• 140° point angle and optimized flute geometry for deep holes up to 5xD

In daily use

This drill is engineered for production environments where consistent hole quality and long tool life are critical. The cylindrical HA shank with 8 mm diameter fits standard collets and hydraulic chucks, while the right-hand cutting direction and two flutes provide balanced cutting forces. The DIN 6537 L standard ensures compatibility with common tool holders and machines.
