Solid Carbide High Performance IQ-Drill, Internal Cooling, 4 Chamfer, H7 Tolerances

IQ-DRILL four-chamfer, 5xD and 8xD with/without interior cooling supply. We optimize your production.

1. This new development from Karnasch meets hightest demands on drill quality. Reming after drilling is often not necessary any more.
2. 4 chamfer are optimal adjusted on the drill-diameter and develop new applications. This additional guide-chamfer stabilizes already on the very beginning of drilling and is responsible for the further drilling process.
3. IQ-drill guarantees maximal alignment accuracy and coaxiality in particular for drilling depths exceeding 5xD.
4. Because of the extraordinary self-centering- ability, also by interruption drill holes, the alignment and concentricity stays almost constant.

Intermediate sizes are available at short notice.

USAGE:

Advantages IQ-Drill: - no center drilling - no predrilling - no counterboring - no drill bushing - high surface quality / reamer quality - high alignment accuracy - tolerance H7

XFN-2 NANO Coating

For steels from soft to medium hard.

• Coating technology: Sputtering
• Micro hardness: 3500 HV0.05
• Coating material: TiAlN
• Coating thickness: Diameter-related
• Max. operating temperature: 1000 degrees C

This universally applicable XFN-2 Nano coating is very well suited for universal use in drilling. By an optional finishing of the already droplet-free coating, an optimal chip transport is guaranteed.

H7 Tolerances
