This 9‑piece set features eight 1/2 in. x 1/2 in. indexable tool holders and a boring bar, each with a black oxide finish and marked shank size. Fitted with uncoated carbide inserts with positive rake angles and chip breakers, the tools provide smooth cutting action and long life on aluminum and other non‑ferrous materials without coating residue. Includes holders QA08R‑20B for cut‑off and grooving, SER0500J11 for threading, SCLCR08‑2J and SCLCL08‑2J for 95‑degree right‑hand and left‑hand turning, SDNCN08‑2J for 62.5‑degree turning, SWGCR08‑2J for 90‑degree turning, SCDCR08‑2J for 45‑degree turning, SCBCR08‑2J for 75‑degree turning, and a S08Q‑SCLCR2 boring bar (min. bore 5/8 in.). Ideal for turning, facing, taper turning, chamfering, external grooving, parting off, threading, and internal boring, the uncoated inserts provide free cutting and excellent chip control on aluminum, brass, and plastics. Suitable for benchtop and floor lathes with 6–12 in. swing and 1/2 in. tool posts or quick‑change holders. Nine uncoated carbide inserts are installed, with additional replacement inserts, extra insert screws, hex keys, and a stainless steel 6 in. 4R ruler included for setup and calibration. Tools and accessories are organized in a fitted aluminum case for safe storage and transport. Designed for machinists, engineers, and hobbyists who require reliable non‑ferrous cutting performance, this set complements quick‑change tool posts and provides durable, easy‑to‑maintain holders with readily available replacement insert kit (Item # 3988‑0012INSERTS). Accusize Industrial Tools 1/2 in. Shank 9‑Piece Indexable Carbide Turning Tool and Boring Bar Set, 3988‑0012, equips machinists and engineers for turning work on aluminum and other non‑ferrous materials. The set contains eight indexable tool holders and a complementary boring bar, each with a 1/2 in. נ1/2 in. shank, black oxide finish, and clear markings. Uncoated carbide inserts are selected for free‑cutting performance on softer alloys. Their positive rake geometry reduces cutting forces, and built‑in chip breakers encourage controlled chip flow and a smooth finish. When an edge dulls, rotate the insert to a fresh edge to resume cutting without downtime. The tool holders cover all common turning tasks—from cut‑off and grooving to threading and turning at multiple lead angles—plus a boring bar for internal machining with a minimum bore of 5/8 in. Together they support turning, facing, tapering, chamfering, external grooving, parting off, threading, and internal boring. Each holder is machined from rigid alloy steel and fits standard 1/2 in. tool posts and quick‑change holders on lathes with 6–12 in. swing. Nine uncoated inserts are 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 during storage and transport. With the dedicated replacement insert kit (Item # 3988‑0012INSERTS) available, this set offers a durable, easy‑to‑maintain solution for clean, controlled cutting on aluminum, brass, and similar materials in professional or home workshops.
