Nine-piece set includes eight 3/8 in. נ3/8 in. indexable tool holders and a matching boring bar; each holder has a smooth black oxide finish and is engraved with its style and size; uncoated carbide inserts with positive rake angles and chip breakers are optimized for aluminum and other non‑ferrous metals. Holder lineup: QA06R‑20J for cut‑off and grooving; SER0375J11 for threading; SCLCR06‑2J and SCLCL06‑2J for 95° right‑ and left‑hand turning; SDNCN06‑2J for 62.5° turning; SWGCR06‑2J for 90° right-hand turning; SCDCR06‑2J for 45° right-hand turning; SCBCR06‑2J for 75° right-hand turning; and a S06M‑SCLCR2 boring bar for internal machining down to 1/2 in. bore. Includes ten extra 10-carbide inserts. Supports turning, facing, tapering, chamfering, external grooving, parting off, threading, and boring operations on aluminum, brass, copper, plastics, and other soft materials; designed for benchtop and small engine lathes with 6–10 in. swings and 3/8 in. tool posts or quick‑change holders. Set includes nine uncoated inserts installed, plus replacement inserts, spare insert screws, hex keys for adjustments, and a stainless steel ruler for setup; all components are stored in a fitted aluminum case for safe transport and organization. Engineered for machinists, engineers, and hobbyists seeking dependable non‑ferrous cutting performance; supported by replacement insert kit Item # 3988‑0038INSERTS for continued productivity. The Accusize Industrial Tools 3/8 in. Shank 9‑Piece Indexable Carbide Turning Tool and Boring Bar Set, 3988‑0038, equips machinists and engineers with a practical selection of holders for accurate work on aluminum and other non‑ferrous materials. The set comprises eight 3/8 in. נ3/8 in. tool holders and a matching boring bar, all finished in black oxide for corrosion resistance and etched with style and size for quick identification. Uncoated carbide inserts are selected for their free‑cutting performance on softer alloys. Each insert features a positive rake angle to minimize cutting forces and a built‑in chip breaker for controlled chip flow and smooth surfaces. When a cutting edge dulls, rotate the insert to another edge and continue working without interruption. The holders handle essential turning tasks: QA06R‑20J manages cut‑off and external grooving; SER0375J11 is configured for threading; SCLCR06‑2J and SCLCL06‑2J provide 95‑degree right‑ and left‑hand turning; SDNCN06‑2J offers 62.5‑degree turning; SWGCR06‑2J covers 90‑degree turning; and SCDCR06‑2J and SCBCR06‑2J supply 45‑degree and 75‑degree turning. The S06M‑SCLCR2 boring bar enables internal turning, facing, and chamfering with a minimum bore of 1/2 inch. Designed for bench and mini lathes with swings around 6–10 inches, the holders fit standard 3/8 in. tool posts and quick‑change systems. Nine uncoated inserts are factory installed, and the kit includes replacement inserts, spare insert screws, two hex keys, and a 6‑in. stainless steel ruler for layout and setup. A fitted aluminum case organizes and protects the tools for storage and transport. With a dedicated replacement insert kit (Item # 3988‑0038INSERTS) available, this set provides dependable, precise cutting performance for machining aluminum, brass, copper, plastics, and other soft materials in professional or home workshops.
