EL-CUT NWKC HSS Taper Shank Drill Bit 35.00 mm, MK4, DIN 345

The EL-CUT NWKC HSS Taper Shank Drill Bit, with a diameter of 35.00 mm and an MK4 Morse Taper shank, is a high-performance tool engineered for demanding drilling operations. Manufactured from high-speed steel (HSS) and featuring an oxidized surface finish, this drill bit is built to withstand the rigors of industrial environments while maintaining structural integrity and cutting efficiency. It adheres to the DIN 345 standard, ensuring compatibility with standard machine tool spindles and consistent performance in metalworking tasks.

Advantages

The primary advantage of this drill bit lies in its robust high-speed steel construction, which provides excellent heat resistance and durability during prolonged use. The oxidized finish serves to reduce friction and improve chip evacuation, which is critical when drilling large diameter holes in steel. The Morse Taper MK4 shank design allows for secure mounting in machine spindles, providing high torque transmission and stability, which minimizes vibration and enhances the precision of the drilled hole.

Suitable for

• Drilling large diameter holes in structural steel and iron
• Industrial metalworking and heavy-duty workshop applications
• Use with stationary drilling machines and milling machines equipped with MK4 spindles

When it may not be suitable

This drill bit is not intended for use with handheld power drills due to its large diameter and Morse Taper shank design. It is also not optimized for drilling non-metallic materials like wood or plastics, where specialized geometry might be required for optimal results.

Key specifications

• Diameter: 35.00 mm
• Shank type: Morse Taper MK4
• Material: High-speed steel (HSS)
• Surface finish: Oxidized
• Standard: DIN 345
• Total length: 339 mm
• Working length: 190 mm

How to use

To use the EL-CUT NWKC drill bit, ensure the machine spindle is clean and free of debris before inserting the Morse Taper shank. Secure the bit firmly into the MK4 socket to ensure proper alignment and torque transfer. Always use a suitable cutting fluid or lubricant to reduce friction and heat buildup during the drilling process. Start the machine at an appropriate speed for a 35 mm diameter bit in steel, applying steady, controlled pressure to allow the cutting edges to remove material effectively without overheating.

What to consider before purchase

• Verify that your machine tool spindle is compatible with an MK4 Morse Taper
• Ensure your drilling equipment has sufficient power and torque for a 35 mm diameter bit
• Check that the machine's worktable can securely clamp the workpiece to prevent movement

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 or dulling to maintain drilling accuracy and prevent tool breakage.
