MAYKESTAG Speeddrill 4.0 Universal Solid Carbide Drill 4.5mm 5xD ANTRADUR

Maykestag Speeddrill 4.0 Universal Solid Carbide Drill 4.5mm 5xD ANTRADUR

Professional 4.50mm HPC solid carbide drill from the Maykestag Speeddrill 4.0 Universal range, featuring ANTRADUR coating, 5xD drilling depth, internal coolant supply, four guide chamfers and a 140° point angle.

The Maykestag Code 6877 Speeddrill 4.0 Universal is a high-performance solid carbide drill developed for accurate and productive holemaking across a broad range of engineering materials. Manufactured to DIN 6537 L and designed for drilling depths up to 5xD, it combines rigid solid-carbide construction with two cutting edges, four guide chamfers and internal coolant supply for controlled, dependable drilling.

This 4.50mm version has a precision h7 cutting diameter, a 6.00mm h6 shank and a 140° drill point. Internal coolant channels deliver coolant directly through the tool towards the cutting zone, while the ANTRADUR coating provides the specialised coated cutting surface specified by Maykestag for this Speeddrill 4.0 series. Its Type N geometry and universal application profile make it particularly versatile for workshops and production environments machining steels, stainless steels, cast iron and selected non-ferrous materials.

Designed for Stable and Accurate Holemaking

The Code 6877 geometry combines two cutting edges with four guide chamfers to support accurate drill guidance as the tool progresses through the workpiece. The 140° point geometry provides the cutting profile specified for the range, while the internal coolant channels bring coolant directly to the working end of the drill. This is especially valuable during deeper 5xD drilling, where effective cooling and chip control become increasingly important.
