High-performance drilling tools in HSSE-Co5 (M35) type for industrial uses.
Fully ground, right-hand turning version with cross grinding.
PFERD drills are completely ground spiral drills.
They are precision ground both in the chip flute and the guide chamfer as well as at the drill tip.
They also have cross grinding. These drills are suitable for highly precise positioning on work pieces and support centring during
drilling.
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 tool life. Exception: when working on aluminium, use kerosene instead of cutting oil.
• In order to avoid corrosion, remove any particles which develop when working on stainless steel (INOX) from the work piece. Clean the work piece chemically or mechanically (etching/polishing, etc.).
