VersionSTEEL


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 offers spiral drills in the STEEL (118 ° point angle) and INOX (135 ° point angle) versions.

High-performance drilling tools in the STEEL in HSSG (M2) 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.
Suitable for general use on steel, cast steel, grey cast iron, annealed cast iron, bronze, brass, aluminium.
Easy centring.
Long tool life.
Recommendations for use
Observe the recommended rotational speeds.
When drilling metals, use a high-quality cutting oil or cooling lubricant, 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.) .
