Description

Boring Bar MTQNR/L 105°, Indexable Insert Holder

The Boring Bar MTQNR/L 105° is designed for negative 60° triangular inserts of the TN family (TNMG, TNMM, TNMA) at a steep 105° approach angle. The specialised approach angle opens up undercuts and profile work in the bore.

M clamping with top clamp and centre hole secures the TNMG insert at the steep 105° approach angle for unusual internal contour geometries. The slim boring bar body is built to reach deep and tight bores without the tool clamping exceeding the available envelope. The black-oxidised CrMo steel construction is tempered and withstands high cutting loads. R and L versions cover right-hand and left-hand tool stations on different lathe types.

When internal turning with the standard TN insert shape at the steep 105° angle, the MTQNR/L delivers contour access in unusual bore geometries.

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

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

Review with rating of 4 out of 5 stars

Funktioniert bisher

Der 105°-Halter macht seinen Job, Plattensitz ist sauber. Für ein endgültiges Urteil noch zu früh, bisher aber alles unauffällig.

Gute Verarbeitung

Werkzeug macht bei mir einen guten Job. Ruhiger Lauf, ordentliche Schaerfe und stabile Schneide. Im Vergleich zu teureren Werkzeugen hält es gut mit. Bin rundum zufrieden.

Stirndrehen klappt gut

Die spitzwinklige Bohrstange erlaubt mir Plandurchgänge an Innenflächen, die ich sonst mit zwei Werkzeugen fahren müsste. Die Klemmung sitzt fest, der Schaft bleibt steif und die Oberfläche kommt sauber.

Bohrstange mit T-Platten-Winkel

Innenkontur mit T-Plattenwinkel läuft sauber, Platte sitzt im Sitz. Zugänglichkeit in Hinterschnitten ist top, bin zufrieden.

Flachbohrungen gut machbar

Die 105-Grad-Bohrstange arbeitet radial schonend, bei dünnwandigen Teilen ein klarer Vorteil. Klemmung sitzt zuverlässig und auch bei mittleren Stahlbohrungen bleibt das Bearbeitungsbild sauber. Für mich eine gute Ergänzung.

Guter Halter für Hinterschnitte

Der steilere Einstellwinkel ermöglicht enge Freistiche, die Stange hält dabei sauber ihre Linie. Bin für den Kurs sehr zufrieden und werde wieder bestellen.

Für enge Konturen brauchbar

Mit 105° kommt man an manche Innenkonturen ran wo normale Stangen aufgeben. Stabil verarbeitet, Platte sitzt präzise. Nicht alltäglich, aber wenn es gebraucht wird, sehr dankbar.

Erster Eindruck okay

Verarbeitung ist ordentlich, aber noch nicht lange im Einsatz. Bisher keine Probleme, mal sehen wie sich das auf Dauer entwickelt.

Bohrstange 105 Grad im Preis ok solide

Die Stange für Stirnbearbeitung innen ist eine günstige Ergänzung im Bestand. Für den Werkstattbedarf im Kleinbetrieb ist das Werkzeug preislich sehr attraktiv, die Ausführung wirkt wertig und die Werkzeugstandzeit auf einem für meine Stückzahlen angemessenen Niveau.
