Maykestag Speeddrill 4.0-Inox HPC Solid Carbide Stub Drill 11.2mm 3xD

Maykestag Speeddrill 4.0-Inox HPC Solid Carbide Stub Drill 11.2mm 3xD

Professional 11.2mm HPC solid carbide stub drill from the Maykestag Speeddrill 4.0-Inox range, manufactured to DIN 6537K with a short 3xD drilling depth, four guide chamfers, internal coolant supply, 140° point geometry and NANODUR coating.

The Maykestag Code 6887 Speeddrill 4.0-Inox is a high-performance solid carbide drill designed for precise, controlled drilling in demanding steels and stainless steels. Its short 3xD configuration provides a rigid drilling setup, while four guide chamfers support stable guidance of the drill in the bore. Internal coolant channels deliver cutting fluid directly towards the cutting zone, helping with cooling and chip evacuation during suitable machine-drilling applications.

What is an HPC solid carbide stub drill? An HPC (High Performance Cutting) solid carbide stub drill is a short, rigid drilling tool designed for productive machining where dimensional accuracy, stable guidance and reliable cutting performance are important. Solid carbide construction provides high rigidity and wear resistance, while the short drilling geometry helps minimise tool deflection. The Code 6887 additionally incorporates internal coolant supply and four guide chamfers for controlled high-performance drilling. Product highlights

Why Choose Maykestag?

Maykestag precision cutting tools are designed around clearly specified tool geometry, dimensional tolerances, cutting materials and application data. With high-performance drilling tools, these characteristics are particularly important because tool rigidity, cutting-edge geometry, coolant delivery and accurate guidance all contribute to bore quality, machining reliability and tool life.

The Code 6887 Speeddrill 4.0-Inox range combines solid carbide construction with short 3xD geometry, four guide chamfers, internal coolant supply, a 140° point angle and NANODUR coating. The combination is designed for professional CNC and machine-drilling applications where repeatable high-performance drilling is required.

Designed for High-Performance Drilling

The Speeddrill 4.0-Inox geometry combines a rigid short-series construction with four guide chamfers to help stabilise the drill as it enters and travels through the workpiece. Internal coolant channels supply coolant directly through the tool, supporting temperature control and chip removal from the cutting zone. Together with its solid carbide construction, NANODUR coating and 140° point geometry, the Code 6887 is designed for productive and accurate drilling across its recommended steel and stainless-steel applications.
