Description

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.

Advantages

Very good chip removal.
High concentricity.
Exact centering and low feed force thanks to cross grinding.
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.

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.
