NWKC HSS Drill Bit 22.5mm with MK2 Taper Shank

The NWKC HSS drill bit with a 22.5 mm diameter and MK2 taper shank is a professional-grade cutting tool engineered for high-performance drilling in metal. Constructed from high-speed steel, this drill bit provides the necessary hardness and heat resistance required for demanding industrial environments. Its design ensures stability and precision, making it a reliable choice for heavy-duty machining tasks where accuracy and material removal efficiency are paramount.

Advantages

This drill bit offers exceptional durability due to its high-speed steel composition, which maintains its cutting edge even under significant thermal stress. The integrated Morse taper MK2 shank allows for a secure and self-centering fit in compatible machine tool spindles, minimizing vibration and ensuring consistent drilling results. The optimized geometry facilitates smooth chip evacuation, preventing clogging and extending the overall lifespan of the tool during continuous operation.

Suitable for

• Drilling holes in structural steel and iron
• Industrial metalworking and machining
• Maintenance and repair operations in workshops
• Use with drill presses and milling machines equipped with MK2 spindles

When it may not be suitable

This drill bit is not intended for use in handheld power drills, as it requires a machine tool spindle with a Morse taper connection. It is also not optimized for drilling in soft materials like wood or plastic, where specialized geometry would be more effective.

Key specifications

• Diameter: 22.5 mm
• Shank type: Morse Taper MK2
• Working length: 155 mm
• Total length: 253 mm
• Material: High-speed steel (HSS)

How to use

To use the drill bit, ensure the machine spindle is clean and free of debris before inserting the MK2 taper shank. Apply firm pressure to seat the taper securely into the spindle. Always use an appropriate cutting fluid or lubricant to reduce friction and heat buildup during the drilling process. Start the machine at a recommended speed for the material being drilled and apply steady, controlled feed pressure to achieve a clean hole.

What to consider before purchase

• Verify that your machine tool spindle is compatible with the MK2 taper standard
• Ensure the drill press has sufficient power for a 22.5 mm diameter bit
• Check that the total length of 253 mm provides enough clearance for your specific workpiece

Usage recommendations

Always wear appropriate personal protective equipment, including safety glasses and gloves, when operating drilling machinery. Regularly inspect the cutting edges for signs of wear and sharpen or replace the bit as necessary to maintain optimal performance.
