Accusize Industrial Tools MDJNL‑12‑3B Indexable Turning Tool Holder, Left Hand, 3/4" Shank x 4‑1/2" OAL, with DNMG332 Carbide Insert, 2302-6016

This left‑hand MDJN L‑12‑3B turning tool holder offers the same robust construction and geometry as its right‑hand counterpart while accommodating set‑ups that require opposite orientation. It has a 3/4" square shank, 4‑1/2" overall length and 1" tool height, providing stability on engine lathes and CNC turning centres. The 3° side cutting edge angle and negative 55° diamond insert geometry support smooth chip flow in turning, facing and copy turning operations. A CVD‑coated DNMG332 insert is supplied, suitable for steel, stainless steel and cast iron. A hardened alloy steel body, finger clamp, clamp screw, lock pin and shim secure the insert and reduce vibration, making this holder a dependable choice for machinists and engineers seeking consistent results.

• Left‑hand MDJN L‑12‑3B turning tool holder with 3° side cutting edge angle for negative 55° diamond DNMG inserts, configured for left‑hand operations.
• 3/4" square shank with 4‑1/2" overall length and 1" tool height accommodates standard toolposts on manual or CNC lathes for stable cutting.
• Accepts DNMG33 CVD‑coated carbide inserts; one DNMG332 insert is included, providing wear resistance when machining steel, stainless steel and cast iron.
• Hardened alloy steel body with finger clamp, clamp screw, lock pin and shim secures the insert and dampens vibration for precise performance.
• Designed for machinists and engineers performing external turning, facing and profiling from roughing to finishing where a left‑hand orientation is required.
