NWKC 26.50mm HSS Morse Taper Shank Drill Bit MK3 DIN 345

The NWKC 26.50mm HSS Morse Taper Shank Drill Bit is a high-performance cutting tool engineered for precision and durability in demanding metalworking environments. Manufactured in accordance with the DIN 345 standard, this drill bit features a robust high-speed steel construction that maintains its cutting edge even under significant thermal and mechanical stress. The integrated MK3 Morse Taper shank allows for a direct and secure connection to machine tool spindles, minimizing runout and ensuring consistent drilling accuracy during heavy-duty operations.

Advantages

The primary advantage of this drill bit lies in its specialized geometry and material composition, which facilitate efficient chip removal and reduced friction during the drilling process. By utilizing high-speed steel, the tool offers an excellent balance between hardness and toughness, preventing premature breakage or dulling. The Morse Taper MK3 interface provides superior torque transmission compared to standard cylindrical shanks, making it an ideal choice for large-diameter hole creation in industrial settings where stability and precision are paramount.

Suitable for

• Drilling large-diameter holes in structural steel and iron
• Industrial machining and manufacturing processes
• Maintenance and repair work in professional workshops
• Heavy-duty drilling operations on stationary drill presses

This drill bit may not be suitable for use with hand-held power drills, as it requires a machine spindle equipped with an MK3 taper socket for proper mounting and operation. Additionally, it is not intended for drilling hardened materials or ceramics, as these applications require specialized carbide-tipped tooling to prevent rapid tool wear.

Key specifications

• Diameter: 26.50mm
• Material: High-speed steel (HSS)
• Shank type: Morse Taper MK3
• Standard: DIN 345

To use this drill bit, ensure that the machine spindle is clean and free of debris before inserting the Morse Taper shank. Firmly seat the taper into the spindle to ensure a secure fit. Always use appropriate cutting fluid or lubricant to reduce heat buildup and extend the life of the tool. Begin the drilling process at a controlled speed and feed rate suitable for the material being processed, ensuring the workpiece is securely clamped to the machine table to prevent movement.

What to consider before purchase

• Verify that your machine tool spindle is compatible with an MK3 Morse Taper
• Ensure the drill press has sufficient power and torque for a 26.50mm diameter bit
• Confirm the material hardness of your workpiece is compatible with HSS tools

For optimal performance and tool longevity, always maintain a consistent feed rate and ensure adequate cooling during the entire drilling operation.
