Turning Tool Holder MSBNR/L 75°, Indexable Insert Holder, Lathe Tool
£67.48
Available, delivery time: 1-3 days
- MSBNR/L turning tool holder with 75° approach angle for longitudinal and face turning with favourable cutting force distribution – the shallow approach angle directs forces into the shank for stability and enables high depths of cut per pass
- Quenched and tempered tool steel body for high bending stiffness and smooth cutting behaviour even during heavy roughing and interrupted cuts
- Compatible with all SN.. indexable inserts in square geometry – as a double-sided negative insert, up to eight usable cutting edges are available for particularly low cost per cutting edge
- Lever clamping for high clamping forces and secure insert positioning even with aggressive cutting parameters and varying stock allowances
- Available in right-hand (MSBNR) and left-hand (MSBNL) versions for bilateral machining strategies and flexible accessibility
- 75° approach angle creates a large contact length on the main cutting edge and distributes the edge load more evenly than steeper approach angles – this reduces localised loading and extends tool life
- Free rake face through lever clamping ensures unobstructed chip flow – particularly advantageous at high material removal rates in roughing operations

Turning Tool Holder MSBNR/L 75°, Indexable Insert Holder, Lathe Tool
The MSBNR/L tool holder with a 75° approach angle is a heavy-duty turning holder for medium to heavy longitudinal and face turning with SN.. indexable carbide inserts. The combination of a shallow approach angle, square negative insert, and lever clamping makes this turning tool a robust workhorse for roughing operations where high metal removal rates and process reliability are the priority. The 75° approach angle directs a significant portion of the cutting forces axially into the shank, reducing the radial load on both the holder and workpiece. This stabilises the cutting process at high depths of cut and allows greater material removal per pass than steeper holders. The square SN insert geometry supports this approach with a long, load-bearing main cutting edge, and as a double-sided negative insert with up to eight cutting edges, it minimises tooling costs per component. The lever clamping system holds the insert securely even under heavy cutting conditions, leaving the rake face completely clear to ensure unobstructed chip evacuation even at high chip volumes. The body, made from heat-treated tool steel, provides the rigid foundation needed to fully exploit the performance of this approach angle and insert geometry combination.
The MSBNR/L is recommended for workshops that rely on a proven combination of lever clamping and square inserts for roughing, expecting greater depth of cut and smoother cutting from the 75° angle than from 45° or 90° holders. Scope of delivery: 1 MSBNR/L holder (without indexable carbide insert) incl. washer, pin, clamp, screw, and wrench.
