PFERD 20057 - HSS Twist Drill Jobber Length M35 17/64" INOX

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.).
