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 HSSG (M2) drill bit for industrial use on STEEL. 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.
Designed for universal use on steel, cast steel, grey cast iron, annealed cast iron, bronze, brass, aluminum.
Easy centering.
Durable.

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!
