Product description

Maykestag Solid Carbide Drill DIN 338 N ALUNIT® 3.90mm

High-performance 3.90mm solid carbide drill with ALUNIT® coating, manufactured to DIN 338 Type N with a 118° point angle and 5×D drilling depth for precision drilling in demanding materials.

The Maykestag Code 6157 is a solid carbide drill with ALUNIT® coating, designed for professional drilling applications. Manufactured to DIN 338 Type N, the drill features a 118° point angle, two cutting edges and a drilling depth capability of up to 5×D. The 3.90mm drill diameter is matched by a 3.90mm h6 shank for precise toolholding.

The ALUNIT® coating provides a hard, wear-resistant cutting surface designed to support reliable performance across a broad range of engineering materials. The DIN 338 Type N geometry provides a versatile configuration for precision drilling applications.

What is a solid carbide drill? A solid carbide drill is manufactured entirely from carbide rather than having a carbide tip brazed onto a steel body. The high rigidity and wear resistance of solid carbide make these drills particularly suitable for precision machining and demanding drilling applications.

Product Highlights

  • Solid carbide construction for high rigidity and wear resistance
  • ALUNIT® coating for enhanced wear resistance and cutting performance
  • 3.90mm drill diameter for precision hole production
  • DIN 338 Type N geometry for versatile drilling applications
  • 118° point angle for reliable centring and cutting performance
  • 5×D drilling depth capability
  • 2 cutting edges for efficient material removal
  • 3.90mm nominal h6 shank diameter
Why choose Maykestag solid carbide drills? Maykestag solid carbide drills combine rigid carbide construction, precision geometry and ALUNIT® coating technology to provide reliable drilling performance across a broad range of engineering materials. The Code 6157 series is designed for accurate, repeatable hole production in professional machining environments.
