Maykestag VHM Solid Carbide Centre Drill 3.15mm DIN 333 A

Precision 3.15mm VHM solid carbide centre drill manufactured to DIN 333 A, featuring Type RN geometry, Form A design, 120°/60° cutting geometry and two cutting edges for accurate centre-hole preparation on workpieces from 30–40mm diameter.

The Maykestag Code 6525 solid carbide centre drill is designed for producing accurately positioned centre holes before subsequent turning, drilling and other precision machining operations. Manufactured from VHM solid carbide, this 3.15mm version combines a rigid 8mm body diameter with a compact 50mm overall length, providing excellent stability for controlled and repeatable centre-hole preparation.

What is a centre drill? A centre drill is a short, rigid cutting tool used to produce an accurately positioned centre hole in a workpiece. The smaller pilot section establishes the centre while the angled cutting section forms the conical seat. This creates a defined reference for subsequent machining operations where accurate positioning, alignment and repeatability are important.

Product highlights

  • VHM solid carbide construction: Provides excellent rigidity, wear resistance and dimensional stability for professional centre-drilling applications.
  • DIN 333 A: Manufactured according to the specified standard for Form A centre drills.
  • 3.15mm pilot diameter: Precision d1 diameter for producing accurately located centre holes.
  • Type RN: Maykestag-specified geometry for the Code 6525 centre-drill range.
  • Form A: Standard centre-drill form for producing conventional centre holes.
  • 120°/60° cutting geometry: Defined geometry for forming the pilot and conical centre profile.
  • Two cutting edges: Z = 2 cutting-edge configuration for controlled centre drilling.
  • 50mm overall length: Compact construction supports rigidity and controlled machining.
  • 30–40mm workpiece range: Maykestag specifies this 3.15mm centre drill for workpieces within this diameter range.

Why Choose Maykestag?

Maykestag precision cutting tools are designed for professional machining applications where controlled tool geometry, dimensional consistency and dependable performance matter. Centre drilling is commonly carried out early in the machining process, making accurate positioning of the centre hole an important foundation for the operations that follow.

The Code 6525 range combines VHM solid carbide construction with DIN 333 A, Form A geometry and clearly specified dimensional tolerances. This provides a rigid and dependable centre-drilling solution for workshops, toolrooms and production environments requiring consistent centre-hole preparation.

Accurate Centre-Hole Preparation

This 3.15mm version combines a 3.15mm pilot diameter with an 8mm body diameter and 50mm overall length. Its 120°/60° cutting geometry forms the pilot and conical centre profile in a controlled operation, while the solid carbide construction provides the rigidity required for accurate positioning. Correct cutting data, secure workholding and accurate machine alignment are important for achieving dependable machining results and good tool life.
