MAYKESTAG Speeddrill 4.0-Inox HPC Solid Carbide Drill 5.4mm 5xD NANODUR

Maykestag Speeddrill 4.0-Inox HPC Solid Carbide Drill 5.4mm 5xD

High-performance 5.4mm solid carbide drill from the Maykestag Speeddrill 4.0-Inox series, engineered for demanding stainless-steel drilling with a 140° point, four guide chamfers, internal coolant supply and wear-resistant NANODUR coating.

The Maykestag Code 6897 Speeddrill 4.0-Inox is an HPC solid carbide drill developed for productive and accurate machining of stainless steels and other demanding materials. Manufactured to DIN 6537 L in a long 5xD design, it combines a rigid solid-carbide construction with optimised cutting geometry, internal coolant channels and four guide chamfers for controlled guidance and excellent hole roundness.

This 5.40mm version features a 6.00mm precision shank, 44mm cutting length and 82mm overall length. The specialised INOX geometry and NANODUR coating are designed to withstand the thermal and abrasive conditions encountered when drilling stainless steels, helping to maintain cutting-edge stability and reliable performance during high-performance production drilling.

Product highlights

• Speeddrill 4.0-Inox: High-performance drill geometry developed specifically with stainless-steel and difficult-material machining in mind.
• Solid carbide construction: Provides high rigidity, dimensional stability and excellent resistance to cutting-edge wear.
• 5xD drilling depth: Long-series geometry designed for drilling to depths of approximately five times the drill diameter.
• DIN 6537 L: Manufactured to the recognised dimensional standard for long-series solid carbide drills.
• Four guide chamfers: Provide additional support and guidance inside the hole, helping achieve excellent roundness and stable drilling.

• Special INOX geometry: Developed for reliable, high-performance drilling in stainless steels and other demanding materials.
• NANODUR coating: High-performance coating developed for demanding drilling applications and improved wear resistance.
• Type N geometry: Precision drill geometry designed for effective chip formation and controlled cutting.
• DIN 6535-HA shank: Cylindrical precision shank for accurate and secure tool holding.

Engineered for Stainless-Steel Drilling

Stainless steels can generate considerable heat at the cutting edge and may work-harden when machining conditions are not correctly controlled. The Speeddrill 4.0-Inox combines specialised cutting geometry, a wear-resistant coating, internal coolant supply and rigid solid-carbide construction to support efficient chip formation and heat removal. The four guide chamfers provide additional support as the drill travels through the workpiece, helping maintain alignment and hole quality throughout the drilling cycle.
