Description Up for sale is a massive, premium collection of 53 vintage Bokum Tool Company (Detroit) industrial machinist tools. This entire lot consists of New Old Stock (NOS) tooling that has never been used. Perfect for manual lathes, CNC machines, or screw machines, this collection features incredibly sharp, factory-ground edges. Incredible Variety of Profiles Included. Bokum Style A: Flat-bottom boring bars for cutting clean 90-degree internal corners. Bokum Style B& J: Standard internal boring, profiling, and shoulder relief tools. ? Bokum Style C (9/16 H-3-C): Internal threading and recessing tools. ? Specialty Grooving & Chamfering:? Dedicated internal O-ring/retaining ring grooving and back-chamfering cutters. ? Micro-Tooling: Stepped-down, small-diameter bars for intricate instrument or watchmaker-scale internal work. External Swan-Neck Cutters: Curved profiles designed for external turning and facing operations. If you operate a manual lathe, CNC machine, or screw machine, this is an instant upgrade to your tooling arsenal, offering a complete matrix of factory-sharp cutting profiles. X Comprehensive Profile & Size Breakdown. Bokum Style A (Flat-Bottom Boring): Includes solid HSS and premium brazed-carbide variants (including clearance-relief heads) engineered to machine flat-bottom blind holes with crisp 90-degree internal corners. Bokum Style B (Standard Boring & Facing): The core workhorse profiling bars featuring sweeping, angled front faces to machine clean internal cylinders and faces. Bokum Style C (Internal Threading): Features precise 60-degree V-point cutters ground perfectly to chase or cut internal screw threads. Bokum Style J & Specialty Profiles: Hard-to-find alphabet variants including shoulder clearance-relief tools, double-ended cutting inserts, and flat-top T-head internal square grooving cutters (for O-ring and retaining snap-ring seats). Micro-Boring Master Series: Includes highly sought-after miniature Size O0B and Size OB / H-O-B small-bore tools (with long-reach neck variants) perfect for instrument makers, model engineers, and watchmakers. These tools are vintage, unused, factory-sharp, and have never touched metal. Some minor cosmetic surface oxidation/storage patina is present on select shanks, which is typical for vintage steel and does not affect the cutting performance. Brand: Bokum Tool Co. (Detroit / Madison Heights). Type: Lathe Boring, Bars, Tradining Grooving, Tools. Material: Solid HSS (High-Speed Steel) & Premium Brazed Carbide-Tipped Due to decades of careful storage, some shanks exhibit cosmetic surface rust bloom/patina which easily cleans off and does not impact tool integrity. What you see in the gallery layout is exactly what you will receive. Please be patient if you are overseas.
