Maykestag Speeddrill+ Universal Solid Carbide Drill Bit 6.8mm 3xD ALTINDUR

High-performance 6.8mm 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 6.8mm version features a precision h7 cutting diameter tolerance, an 8mm h6 shank and two cutting edges. Its 79mm overall length and 34mm 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.

Built for accurate short-hole drilling

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.

Product highlights

Solid carbide construction: Provides high rigidity, dimensional stability and wear resistance for professional precision drilling.
6.8mm precision cutting diameter: Manufactured to an h7 diameter tolerance for controlled hole production.
DIN 6537 K: Short-series drill geometry designed for rigid and accurate drilling applications.
3xD drilling depth: Designed for holes up to three times the nominal drill diameter.
Internal coolant supply: Coolant channels help deliver cutting fluid directly to the working area for improved cooling and chip evacuation.
ALTINDUR coating: Maykestag's specified high-performance coating for the Code 6718 range, supporting cutting-edge durability and wear resistance.
140° point angle: Precision point geometry suited to controlled machining in the materials recommended by Maykestag.
Type N geometry: Universal drill geometry intended for a broad selection of engineering materials.
Two cutting edges: Balanced two-edge cutting geometry for controlled and efficient drilling.
DIN 6535-HA shank: Precision cylindrical shank configuration for accurate concentric holding in suitable toolholders.

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 6.8mm 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.

What is ALTINDUR coating?

ALTINDUR is the coating specified by Maykestag for the Code 6718 Speeddrill+ Universal range. A hard tool coating forms a protective surface over the cutting edges and helps the drill withstand the friction, heat and abrasive wear generated during machining. This supports dependable cutting performance and helps preserve the accurately ground cutting geometry over a longer service period when the drill is used with the correct machining parameters.

The combination of ALTINDUR coating and solid carbide construction is particularly valuable in a universal drill intended to work across several steel grades, stainless steel, cast iron and selected non-ferrous materials.

What does DIN 6537 K mean?

DIN 6537 K identifies the short or stub-length form of this precision drill. The shorter construction increases rigidity and reduces the tendency of the drill to deflect compared with a longer tool. For the Code 6718 range, Maykestag specifies a drilling depth of up to 3xD, meaning up to three times the nominal drill diameter.

For this 6.8mm drill, the nominal 3xD drilling depth corresponds to approximately 20.4mm, subject to the workpiece material, machining conditions and application.

Why internal coolant matters

The Code 6718 incorporates internal coolant supply, allowing cutting fluid to be delivered through the drill towards the cutting zone. This helps control heat at the cutting edges and assists chip movement away from the hole. Effective coolant delivery is particularly valuable in production drilling, where heat and restricted chip space can affect cutting performance and tool life.

Understanding the h7 and h6 tolerances

The 6.80mm cutting diameter is manufactured to h7 tolerance, while the 8.00mm shank is manufactured to h6 tolerance. These precision tolerance classes help provide consistent drill dimensions and accurate toolholding, both of which are important for concentric running and controlled hole production.

Get the Right Cutting Data SpeedGuide Calculator

MaySpeedGuide: Maykestag recommends using the MaySpeedGuide to determine the appropriate cutting conditions for the tool, workpiece material and machining application.

Precision setup matters. With a 6.8mm solid carbide drill, accurate toolholding, minimum runout, correct cutting data and reliable coolant delivery are important for achieving good hole quality and protecting the cutting edges.
