Description

Drilling tools with cross grinding for industrial uses. Fully ground, right-hand turning versions that produce precise drill holes thanks to their high concentricity and exact centring. PFERD TOOLS offers spiral drills in the STEEL (118 ° point angle) and INOX (135 ° point angle) versions.

High-performance drilling tools in the INOX in HSSE-Co5 (M35) version for industrial uses. Fully ground right-hand turning version with cross grinding that produces precise drill holes thanks to their high concentricity and exact centring.

Advantages

Very good chip removal.
High concentricity.
Exact centring and low feed force thanks to cross grinding.
Particularly well suited for tough and hard materials, such as alloyed and high-strength steel, stainless steel (INOX).
Robust tip profile.
Very long tool life.
Very good temperature resistance due to Co content.

Recommendations for use

Observe the recommended rotational speeds.
When drilling metals, use a high-quality cutting oil or coolant, if possible. This facilitates smooth running and extends the drill tool life. Exception: when working on aluminium, use kerosene instead of cutting oil.
When working on stainless steel (INOX), remove any particles that break away from the workpiece in order to avoid corrosion. Clean the workpiece chemically or mechanically (etching/polishing, etc.).

Safety notes

Wear eye protection!
Follow the safety instructions!
