Maykestag VHM Solid Carbide Centre Drill 1mm DIN 333 A

Product information

Maykestag VHM Solid Carbide Centre Drill 1mm DIN 333 A Precision 1mm 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 4–8mm diameter. The Maykestag Code 6525 solid carbide centre drill is a precision cutting tool designed for producing accurately positioned centre holes before subsequent turning, drilling or other machining operations. Manufactured from VHM solid carbide, its compact construction provides excellent rigidity and dimensional stability, helping the 1mm pilot section maintain precise alignment under suitable machining conditions. 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 small pilot section establishes the centre while the angled cutting section forms the required conical seat. This controlled geometry creates an accurate reference point for subsequent machining and is especially valuable where alignment, concentricity and repeatability are important. Product highlights • VHM solid carbide construction: Provides high rigidity, dimensional stability and excellent wear resistance for precision centre drilling. • DIN 333 A: Manufactured to the specified dimensional and geometric requirements for Form A centre drills. • 1mm pilot diameter: Precision d1 diameter designed for accurately locating and producing small centre holes. • RN geometry: Right-hand cutting, normal geometry for controlled centre-drilling performance. • Form A: Conventional centre-drill form for producing standard centre holes. • 120°/60° cutting geometry: Precisely formed geometry for producing the pilot and conical centre profile. • Two cutting edges: Z = 2 configuration provides balanced cutting action during centre-hole preparation. • 31.5mm overall length: Compact construction provides high rigidity and helps minimise deflection. • 4–8mm workpiece range: Maykestag specifies this 1mm centre drill for workpieces within the 4–8mm diameter range. Why Choose Maykestag? Maykestag precision cutting tools are engineered for professional machining applications where geometry, dimensional accuracy and repeatability matter. Centre drilling is frequently the first precision machining operation performed on a component, so an accurately produced centre hole can play an important role in the alignment and quality of the operations that follow. The Code 6525 range combines solid carbide construction with DIN 333 A geometry, Type RN design and tightly controlled dimensions. This provides a rigid and dependable centre-drilling solution for professional workshops, toolrooms and production environments where repeatable positioning and accurate machining are essential. Accurate Centre-Hole Preparation With a 1mm pilot diameter, 3.15mm body diameter and compact 31.5mm overall length, this centre drill provides a highly rigid cutting setup. Its solid carbide construction is particularly valuable at small diameters where resistance to deflection and precise cutting-edge geometry are important. The 120°/60° geometry produces the pilot and conical centre profile in a controlled operation, creating an accurate reference for subsequent machining.
