Kennametal DFS Indexable Drill Inserts

Higher Productivity and Profitability

• Achieve highest metal removal rates and excellent chip evacuation due to advanced chip flutes and non-central and increased cooling channels.
• Make use of squared outboard inserts that offer four economic cutting edges where needed.
• Benefit from a complete product portfolio offering standard L/D ratios up to 5 x D.

Versatility

• Drill holes up to 5 x D in steel, cast iron, ductile iron, stainless steel, and non-ferrous materials.
• Use where speed and economy are prime considerations.
• Apply DFS drills to straight holes, inclined entries and exits, interrupted cuts, and rough or welded entry surfaces.
• Use X-offset on turning machines to adjust the drill diameter, eliminating the need for specials in many applications and on machining centres to reach tolerance optimisation.
• Eccentric chuck available as standard.

Reliability

• Benefit from high-accuracy holes independently from feed rates applied.
• Gain outstanding results by applying the Beyond DFS inserts.
• High wear resistance at interrupted cuts due to squared outboard insert.

Customisation

• Intermediate diameters, multistep drills, and other non-standard shanks are available.
• Smaller and larger diameters available.
