Maykestag Speeddrill+ Universal Solid Carbide Drill Bit 2.1mm 3xD ALTINDUR
High-performance 2.1mm solid carbide short-series drill with 3xD drilling depth, internal coolant supply, ALTINDUR coating and a 140° point angle for precise, efficient drilling across a broad range of engineering materials.
The Maykestag Code 6718 Speeddrill+ Universal is a precision solid carbide drill designed for professional machining where accuracy, stability and reliable tool life matter. Manufactured to DIN 6537 K, this short-series drill combines a rigid design with Type N geometry, a 140° drill point and internal coolant channels for controlled high-performance drilling up to 3xD.
The 2.1mm version features a precision h7 cutting diameter tolerance, a 4mm h6 shank and two cutting edges. Its 55mm overall length and 20mm flute length provide the geometry specified by Maykestag for this diameter, supporting accurate and repeatable hole production when used in a suitable precision machine and toolholding system.
The Code 6718 is designed specifically for drilling depths up to three times the drill diameter. The short DIN 6537 K configuration provides greater rigidity than a longer drill of comparable diameter, while the internal coolant supply delivers coolant directly towards the cutting zone. This combination is particularly valuable in production environments where repeatability, chip control and dependable cutting-edge performance are important.

Why Choose Maykestag?
Maykestag manufactures precision cutting tools for professional machining applications where repeatability, dimensional accuracy and dependable cutting performance are essential. The Code 6718 range brings together solid carbide construction, internal coolant delivery, a short rigid drilling geometry and ALTINDUR coating to create a highly capable universal drilling solution.
Its broad material suitability makes the Speeddrill+ Universal particularly useful in workshops and production environments that machine several different material groups and require a dependable drill platform rather than a highly specialised drill for only one workpiece material.
Precision, Rigidity and Cooling Working Together
Precision drilling places considerable demands on machine accuracy and tool rigidity. With a 2.1mm cutting diameter, the short construction helps minimise unnecessary tool deflection, while the h7 cutting diameter and h6 shank tolerances support accurate positioning and concentric running. Internal coolant channels further assist the drilling process by carrying coolant towards the cutting zone, helping manage heat and move chips away from the cutting edges.
