PFERD TOOLS 25203929 SPB DIN 1897 HSSE N 1,5 INOX Stainless steel (INOX) Twist drill bit 1.5 mm Total length 31 mm DIN 1

Drilling tools with cross-grinding for industrial applications Fully ground, right-rotating versions, which generate precise drill holes thanks to their high concentricity and exact centering. Twist drill bits offer PFERD in the STEEL (118° tip angle) and INOX (135° tip angle) versions. High performance drilling tools in the INOX model in HSSE-Co5 (M35) for industrial applications. Fully ground right-hand cut design with cross polished section, which produces accurate boreholes thanks to its high concentricity and exact centering. Extra-short twist drills according to DIN 1897 preferred for robot and machine use.

Benefits:
- Particularly suitable for tough and hard materials such as alloyed and high-strength steel, stainless steel (INOX).
- Stable tip design.
- Very long service life.
- Very good temperature resistance due to co-component.
- Very good chip removal.
- High run-out accuracy.
- Precise centering and low feed force thanks to cross-ground.

Application recommendations:
- Observe recommended speeds.
- When drilling metals, use high-quality cutting oil or coolant as far as possible. This promotes smooth running and extends the lifetime of the drill. Exception: Apply petroleum instead of cutting oil when machining aluminum.
- Remove the particles from the workpiece when machining stainless steel (INOX) to prevent corrosion. Clean the workpiece chemically or mechanically (etching/polishing, etc.).
