Description

Turning Tool Holder MTFNR/L 91°, Indexable Insert Holder, Lathe Tool

The Turning Tool Holder MTFNR/L 91° is an ISO turning tool holder for external longitudinal, facing, and contour turning with indexable inserts of the TN family (TNMG, TNMM, TNMA, 60° triangular) at a 91° approach angle. This angle is specialised for universal applications with an optimised balance between longitudinal and facing stability.

M clamping with top clamp and centre hole secures a reproducible insert seat at varying cutting loads and interrupted cuts. The black-oxidised tempered steel body (40-43 HRc) withstands medium cutting loads. The 91° approach angle offers an optimised geometry for combined longitudinal and facing operations without frequent tool changes. The negative TN insert geometry (60° triangular) with six cutting edges and a high material cross-section also handles rough cutting conditions. The holder is proven for flexible job shop production with mixed turning tasks. The R/L variant choice follows the turret layout.

The MTFNR/L 91° is the proven universal holder for flexible job shop production with indexable inserts of the TN family (TNMG, TNMM, TNMA) and an optimised angle balance.

Scope of delivery: 1 MTFNR/L holder (without indexable insert) including shim, pin, clamp, screw, and wrench.

Note: The illustration shows the right-hand version (R).

Gute Schulterbearbeitung

91 Grad passt für mich sehr gut, sauberes Schulterdrehen und die Klemmung hält bei mir auch bei knackigerer Zustellung. Verarbeitung sehr sauber.

Klemmhalter Klemmhalter 91 Grad Serienfertigung

Den Halter setze ich auf unserer Haas ST-30 in mehrwöchiger Serienfertigung von 42CrMo4-Wellen ein, die Platten sitzen über alle Wechsel spielfrei und die Maßhaltigkeit der Konturen bleibt konstant. Solide Verarbeitung erkennbar.

Halter überzeugt in der Praxis

Den Klemmhalter habe ich auf der Haas ST-20 mehrere Wochen in verschiedenen Materialien laufen lassen. Nichts ist auffällig, die Wendeplatten sitzen stabil und die Wiederholgenauigkeit stimmt. Auch nach mehreren Plattenwechseln bleibt die Einstellung sauber. Für unseren Alltag eine gute Investition.

91°-Halter für Planaufgaben nützlich

Der 91°-Halter hält die trigonale Platte sauber, keine Bewegung beim Drehen. Mit der passenden Platte läuft er zuverlässig. Klemmung ist stramm, Plattensitz sauber gefräst. Für Planaufgaben und leichte Schruppgänge eine solide Grundlage.

Halter sitzt bombenfest im Revolver

Auf einer Haas ST-20 im Einsatz bei 42CrMo4. Für Längs- und Plandrehen bei mir der Standard. Stabiler Grundkörper, Schrauben ziehen sauber. Würde ich wieder kaufen.

Fair für den Preis

Gute Preisgestaltung, das Werkzeug sieht wertig aus, im Einsatz in 42CrMo4 ersten Eindrücken nach brauchbar, ich beobachte weiter. Weniger Geld, vergleichbare Leistung, fertig.
