Twist drill bit KWB 217080 1 pc Right hand rotation

The KWB 217080 twist drill bit is a high-performance, extra-long tool designed for precision drilling in demanding industrial applications. Engineered with a right-hand rotation and a type N geometry, this drill bit ensures efficient material removal and consistent performance across a wide range of metallic and synthetic surfaces. Its robust construction and specialized tip design make it a reliable choice for professionals requiring deep-hole drilling capabilities.

Advantages

This drill bit features a precision-ground finish that enhances cutting accuracy and longevity. The 135-degree tip angle, combined with the cross-ground point according to DIN 1412 C, allows for excellent centering and reduced feed pressure, preventing the bit from wandering on the workpiece surface. Its extra-long design provides the necessary reach for deep drilling tasks, while the industrial-grade material composition ensures durability and resistance to wear during intensive use.

Suitable for

• Drilling in steel and alloyed steel
• Working with cast steel and die castings
• Processing sintered steel
• Drilling in non-ferrous metals
• Applications involving hard plastics

When it may not be suitable

This drill bit is not intended for use on masonry, concrete, or extremely hardened materials that require specialized carbide-tipped masonry drills. Due to its extra-long length, it may be prone to vibration or snapping if used in handheld drills without proper support or if the drilling speed is not correctly managed.

Key specifications

• Standard: DIN 340
• Rotation: Right-hand cut
• Tip angle: 135 degrees
• Point geometry: Cross-ground (DIN 1412 C)
• Type: N
• Shank type: Cylindrical
• Material finish: Self-colour

How to use

Insert the cylindrical shank of the drill bit securely into a compatible drill chuck, such as a geared rim chuck. Ensure the bit is centered and tightened firmly before starting the operation. Begin drilling at a low speed to establish a pilot hole, then gradually increase the speed according to the material being processed. Always maintain a steady, perpendicular angle to the workpiece to prevent the bit from bending or breaking, especially when drilling to the full depth of the bit.

What to consider before purchase

• Verify that your drill chuck is compatible with the cylindrical shank diameter.
• Ensure the extra length of the drill bit is appropriate for your specific project depth.
• Check that your drilling equipment supports the required speed for the material being drilled.

Usage recommendations

For optimal results and to extend the life of the drill bit, use a suitable cutting oil or lubricant when drilling into metals. Always wear appropriate eye protection and secure the workpiece firmly with clamps before beginning the drilling process.
