Maykestag VHM Solid Carbide Centre Drill 0.8mm DIN 333 A

Product information

Maykestag VHM Solid Carbide Centre Drill 0.8mm DIN 333 A Precision 0.8mm solid carbide centre drill manufactured to DIN 333 A, featuring RN geometry, Form A design, 120°/60° cutting geometry and two cutting edges for accurate centre-hole preparation on workpieces from 4–6mm diameter. The Maykestag Code 6525 solid carbide centre drill is a precision cutting tool designed for producing accurate centre holes before subsequent turning, drilling or other machining operations. Manufactured from VHM solid carbide, it combines high rigidity with excellent dimensional stability, helping the small 0.8mm pilot section maintain accurate positioning under suitable machining conditions. What is a centre drill? A centre drill is a short, rigid cutting tool used to create an accurately positioned centre hole in a workpiece. The small pilot section establishes the centre while the larger angled cutting section forms the required conical seat. This controlled geometry provides an accurate starting point for machining operations and is especially useful where precise alignment and repeatability are important. Product highlights • VHM solid carbide construction: Provides excellent rigidity, dimensional stability, wear resistance and cutting-edge strength for precision machining. • DIN 333 A: Manufactured to the specified dimensional and geometric requirements for Form A centre drills. • 0.8mm pilot diameter: Precision d1 diameter for producing small and accurately located centre holes. • RN geometry: Right-hand cutting, normal-helix geometry designed for controlled and dependable centre drilling. • Form A: Standard centre-drill form designed for producing conventional centre holes. • 120°/60° cutting geometry: Precisely formed point and centre-hole geometry for controlled cutting and accurate centring. • Two cutting edges: Z = 2 cutting-edge configuration provides balanced cutting action during centre-hole preparation. • Compact 25mm overall length: Short, rigid construction helps minimise deflection and supports accurate positioning. • 4–6mm workpiece range: Maykestag specifies this 0.8mm centre drill for workpieces in the 4–6mm diameter range. Why Choose Maykestag? Maykestag precision cutting tools are engineered for professional machining applications where geometry, dimensional accuracy and consistency are essential. Centre drilling is often the first precision operation performed on a component, which means the accuracy of the centre hole can directly influence the alignment and quality of subsequent machining. The Code 6525 series combines solid carbide construction with DIN 333 A geometry, an RN cutting design and carefully controlled dimensional tolerances. The result is a rigid precision centre drill suited to workshop, toolroom and production environments where repeatable positioning and dependable cutting performance are required. Accurate Centre-Hole Preparation With a 0.8mm pilot diameter, 3.15mm body diameter and compact 25mm overall length, this centre drill is designed to provide a highly rigid cutting setup. Its solid carbide construction is particularly valuable at small diameters, where resistance to deflection and accurate edge geometry are important. The 120°/60° geometry creates the pilot and conical centre profile in a controlled operation, helping establish an accurate reference for subsequent machining.
