Drill bits with cross grinding for industrial use. Fully ground, right-hand turning to produce precise drill holes due to their high concentricity and exact centering. PFERD offers spiral drills STEEL (118 ° point angle) and INOX (135 ° point angle) versions. High-performance HSSE-Co5 (M35) drill bit for industrial use on INOX and other non-ferrous metals. The fully ground right-hand turning design with cross grinding provides an exact centering drill tip and a high level of concentricity.
Special features
- Ideal for tough and hard materials, such as alloyed and high-strength steel, stainless steel (INOX).
- Robust tip profile.
- Very durable.
- Very good temperature resistance due to Co content.
- Very good chip removal.
- High concentricity.
- Exact centering and low feed force thanks to cross grinding.
Recommendations for use
- Observe the recommended rotational speed.
- When drilling metals, use a high-quality cutting oil or cooling lubricant, if possible. This facilitates smooth running and extends the drill service life. Exception: when working on aluminum, use kerosene instead of cutting oil.
- To avoid corrosion when working on stainless steel (INOX), remove any particles that break away from the workpiece. Clean the workpiece chemically or mechanically (etching/polishing, etc.).
Safety notes
- Wear eye protection.
- Follow the safety instructions.
