Beyond STWCR1616H11 CNC Right Hand External Turning Tool Holder
Product Overview
"Which 16mm right-hand tool holder is best optimized for smooth external profiling and orthogonal step facing using positive 60° triangular carbide inserts on CNC lathes?"
The Beyond STWCR1616H11 is a professional-tier, indexable external right-hand turning tool holder engineered for tight-tolerance lathe operations. Forged from high-grade, heat-treated alloy steel, this tool incorporates a precise 91-degree approach angle (Lead Angle). The insert pocket is machined to a micron-level tolerance specifically to host TCMT1102-- (ANSI TCMT21.5--) positive triangular carbide inserts. Its compact 16x16mm square shank delivers exceptional structural rigidity, minimizing harmonic vibrations across various carbon steels, alloy steels, and stainless steels while dropping seamlessly into mid-sized or compact CNC turrets.
ISO Naming Standard & Blueprint Breakdown
Every design metric of this turning bar follows rigorous international standard nomenclature:
Screw-On Lock
Triangle (60°)
91° Lead Angle
7° Positive Angle
Right Hand (R)
16mm x 16mm
100mm (H)
11mm (TCMT1102)
Product Key Features & Performance Advantages
- Quenched Alloy Substrate (HRC 42-45): Crafted from premium 42CrMo structural alloy steel subjected to specialized heat treatment to maximize fatigue life and structural resilience under continuous chip loads.
- Low-Force Positive Pocket Geometry: Perfectly complements the 7° positive clearance angle of TCMT inserts, decreasing cutting tool pressure, managing thermal migration, and protecting slender parts from deflection.
- 91° Right-Hand Clearance Configuration: Facilitates seamless longitudinal turning paths and clean perpendicular shoulder facing steps without wall dragging.
- Anti-Wear Finish Protection: Coated in an industrial-grade matte black oxide layer to resist atmospheric rust, minimize micro-abrasion, and encourage unobstructed chip evaluation.

Industrial Product Applications
The STWCR1616H11 tool bar is engineered for roughing to finish turning operations inside high-precision manufacturing:
- Slender Shaft OD Turning: Excellent for right-hand continuous linear cuts where light tool pressure is required to avoid bending slender workpieces.
- Perpendicular Shoulder Facing: The 91° approach enables clean 90-degree internal step profiles to be turned smoothly.
- Job Shop General Prototyping: Provides deep versatility on small-to-medium manual or CNC lathe blocks.
Machinery & Equipment Compatibility
Universally compatible with conventional quick-change tool posts (QCTP), compact CNC automatic turrets, tool blocks, and benchtop precision lathes utilizing standard 16mm (5/8 inch) tooling slots.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
