Features and Benefits

Drill Fix DFSP

DFSP is the new name of the now extended Drill Fix DFS indexable drilling platform. The standard diameter range is now expanded starting from .551-2.125" (14-55mm) in L/D ratios 2 x D, 3 x D, 4 x D, and 5 x D. Like the DFS, the DFSP combines the economically squared outboard insert with the superior centering capabilities of the trigon inboard insert. DFSP indexable drills offer increased metal removal rates combined with high surface quality and hole straightness. Boost your productivity even further and achieve outstanding results in steel, stainless steel, and cast iron with the latest Beyond insert grades.

Higher Productivity and Profitability Versatility Reliability Customization LP geometry for outboard SP.X inserts and DS geometry for inboard DFT inserts

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. 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 DFSP 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 centers to reach tolerance optimization. Eccentric chuck available as standard. Quick and easy change of insert grade and/or geometry to address material and application changes. Benefit from high accuracy holes independently from feed rates applied. Gain outstanding results by applying the Beyond grades for DFT and SPGX/SPPX. High wear resistance at interrupted cuts due to squared outboard insert. Make use of the DFSP cartridge solution to extend your diameter range up to 3.35" (85mm) in L/D ratios up to 5 x D. Intermediate diameters, multistep drills, and other non-standard shanks are available. Contact our engineered solution team for available offers. Enables excellent performance and process stability in applications with long chipping materials. Use for low carbon steel, difficult stainless steel, and non-ferrous materials where long chips can be an issue. Available in grade KCU40 .
