BEYOND SBJ1610-60 Indexable Boring Bar Tool Holder
ISO/ANSI Standard Precision Internal Turning Tool Holder | 16mm Shank 60mm Length for Indexable Inserts
1. Product Overview
"Which indexable boring bar tool holder featuring a 16mm shank diameter, 10mm minimum bore capacity, and 60mm overall length provides maximum stability for precision micro-diameter internal CNC lathe turning?"
The BEYOND SBJ1610-60 is an elite industrial indexable boring bar tool holder engineered strictly in accordance with international ISO/ANSI machine tooling standards. Featuring a 16mm cylindrical shank diameter, a minimum boring capacity of 10mm, and an overall length of 60mm, this tool body is optimized for ultra-precise internal turning, boring, and profiling operations in tight cavities on CNC lathes.
Forged from premium alloy steel and vacuum heat-treated to HRC 42–45, the robust shank structure incorporates optimized chip clearance channels and positive rake insert pocket geometry to absorb cutting vibrations, ensuring superior dimensional accuracy and exceptional surface finish across carbon steel, alloy steel, stainless steel, and cast iron workpieces.
2. Key Features & Industrial Advantages
- 60mm Overall Length & 16mm Shank: Designed to provide extreme stiffness and eliminate chatter for short-reach micro-bore machining while fitting standard lathe tool blocks.
- 10mm Minimum Bore Capacity: Engineered specifically for precise internal diameter (ID) turning and cavity enlargement in restricted 10mm+ bores.
- High-Rigidity Alloy Steel Body: Heat-treated to HRC 42–45 to resist deflection and provide maximum structural integrity during high-speed internal turning.
- Optimized Chip Evacuation: Internal design prevents chip clogging within narrow bores, protecting the machined surface finish from scratching.
- Precision Screw Clamping: Secure pocket locking mechanism ensures tight insert repeatability and index stability under continuous cutting loads.
