HSS Drill Bit 41.00 mm, MK4 Taper Shank, DIN Standard, Oxidized Finish

The HSS drill bit with a 41.00 mm diameter is a professional-grade cutting tool engineered for heavy-duty drilling operations in metal. Featuring a robust MK4 Morse taper shank, this drill bit is designed for secure and stable mounting in industrial drill presses and milling machines. The tool is manufactured in accordance with DIN standards, ensuring high precision, dimensional accuracy, and reliable performance in demanding workshop environments.

Advantages

The primary advantage of this drill bit is its high-speed steel construction, which provides excellent hardness and heat resistance during prolonged drilling tasks. The oxidized finish serves a dual purpose by enhancing the surface hardness for superior wear resistance and facilitating smoother chip evacuation, which prevents clogging and reduces friction. The MK4 taper shank ensures a rigid connection, minimizing vibration and allowing for efficient power transmission from the machine spindle to the cutting edge.

Suitable for

• Heavy-duty drilling in structural steel and cast iron
• Industrial metalworking and manufacturing applications
• Operations requiring high precision in drill presses and milling machines

This drill bit may not be suitable for handheld power drills, as the MK4 taper shank requires a specific machine spindle interface. It is also not intended for drilling in soft materials like wood or plastic where high-speed steel geometry might cause tearing rather than clean cutting.

Key specifications

• Diameter: 41.00 mm
• Shank type: MK4 Morse taper
• Material: High-speed steel (HSS)
• Surface finish: Oxidized
• Standard: DIN compliant

To use this drill bit, ensure the machine spindle is clean and free of debris before inserting the MK4 shank. Secure the workpiece firmly in a vice or clamp to prevent movement during the drilling process. Apply appropriate cutting fluid or coolant to the contact point to manage heat buildup and extend the lifespan of the cutting edges. Begin drilling at a low rotational speed, gradually increasing it as the bit penetrates the material.

What to consider before purchase

• Verify that your machine tool is equipped with an MK4 Morse taper spindle
• Ensure the drill press has sufficient power and torque to handle a 41.00 mm diameter bit
• Check the compatibility of your cooling system for deep hole drilling

For optimal results and to prevent premature wear, always maintain a consistent feed rate and ensure the drill bit is properly lubricated throughout the entire drilling operation.
