NWKC HSS Taper Shank Drill Bit 39 mm MK4

The NWKC HSS Taper Shank Drill Bit with a 39 mm diameter is a professional-grade cutting tool engineered for demanding metalworking tasks. Featuring a Morse Taper 4 (MK4) shank, this drill bit ensures a secure and stable fit in industrial drilling machines, lathes, and radial drills. Manufactured from high-speed steel (HSS), the bit provides excellent heat resistance and structural integrity, allowing for consistent performance when drilling through tough materials.

Advantages

This drill bit stands out due to its robust construction and precision engineering. The high-speed steel composition maintains a sharp cutting edge even under high thermal loads, which is essential for maintaining accuracy in industrial environments. The Morse Taper 4 shank design facilitates rapid tool changes and provides superior torque transmission, minimizing the risk of slippage during heavy-duty operations. Its geometry is optimized for efficient chip evacuation, which prevents clogging and reduces the frequency of interruptions during deep hole drilling.

Suitable for

• Industrial metal drilling applications
• Heavy-duty drilling on lathes and radial drilling machines
• Creating large-diameter holes in steel and cast iron
• Precision engineering and manufacturing tasks

This drill bit is not suitable for use in standard handheld power drills or cordless drills, as it requires a machine tool equipped with an MK4 spindle. It is also not intended for drilling into masonry, concrete, or soft materials like wood where specialized geometry is required for optimal results.

Key specifications

• Diameter: 39 mm
• Shank type: Morse Taper 4 (MK4)
• Material: High-speed steel (HSS)
• Total length: 349 mm
• Working length: 200 mm

How to use

To use the NWKC HSS drill bit, ensure that the machine spindle is clean and free of debris before inserting the Morse Taper shank. Firmly seat the shank into the spindle to ensure a secure connection. Secure the workpiece tightly using clamps or a machine vice to prevent movement during the drilling process. Set the machine to the appropriate rotational speed and feed rate based on the material being drilled. Always apply a suitable cutting fluid or coolant to the drill point to reduce friction, dissipate heat, and extend the lifespan of the tool.

What to consider before purchase

• Verify that your machine tool is compatible with a Morse Taper 4 (MK4) shank.
• Ensure the machine has sufficient power and torque to handle a 39 mm diameter drill bit.
• Check the clearance of your machine to accommodate the 349 mm total length.
• Confirm the material compatibility for high-speed steel tools.

Usage recommendations: Regularly inspect the cutting edges for signs of wear or dulling. If the drill bit shows signs of overheating or excessive vibration, reduce the feed rate and increase the flow of coolant to maintain precision and prevent premature tool failure.
