GT Precision Modular Vise Jaws are a versatile jaw system developed for use with GT-series precision machine vises, including GT100, GT125, GT150, GT175, GT200 and GT300 models.
Different machining jobs require different workholding surfaces. Instead of changing the entire vise, operators can select the appropriate modular jaw style to match the workpiece shape, clamping position and machining process. This improves setup flexibility and helps workshops build a more practical CNC workholding solution.
Zhenghao Machinery is a China-based precision machine tool accessory manufacturer founded in 2016. We support distributors, machine tool accessory brands and machining-equipment suppliers with standard vise jaws, replacement parts and OEM-customized clamping solutions.
The GT modular jaw system includes several common jaw styles for different workholding requirements:
Jaw Type | Name | Typical Application |
A | Flat Jaw | General-purpose clamping of flat or square workpieces |
B | Step Jaw | Multi-level clamping and elevated workpiece positioning |
C | Lattice Jaw | Improved gripping contact for selected workpiece surfaces |
D | Groove Jaw | Locating or clamping workpieces with matching grooves or profiles |
E | Threaded Jaw | Workholding configurations requiring threaded fixing points |
F | V-Type Jaw | Clamping round bars, shafts, tubes and cylindrical components |
G | Square Jaw | Supporting square, rectangular or profile-shaped workpieces |
Note: Please confirm your vise model, jaw mounting dimensions, workpiece geometry and required clamping method before ordering.
A modular jaw system gives machine shops more workholding choices without purchasing multiple dedicated vises. Flat, stepped and V-type jaws can be selected according to the part shape and machining operation.
These jaws are available for the following GT vise sizes:
GT100
GT125
GT150
GT175
GT200
GT300
GT modular vise jaws can be used in CNC milling, drilling, grinding and general precision machining applications where repeatable workpiece positioning is required.
For machine vise brands, industrial distributors and tool accessory importers, Zhenghao Machinery can support OEM jaw programs based on drawings, samples or functional requirements.
Step Jaw Width: 3 mm
Vise Model | Available Step Depths (mm) |
GT100 | 3, 5, 8, 13 |
GT125 | 3, 5, 8, 13, 18, 23 |
GT150 | 3, 5, 8, 13, 18, 23, 28 |
GT175 | 3, 5, 8, 13, 18, 23, 28 |
GT200 | 3, 5, 8, 13, 18, 23, 28 |
GT300 | 3, 5, 8, 13, 18, 23, 28 |
Step jaws are useful when the workpiece needs to be held at a selected height, when additional clearance is needed for machining, or when different clamping levels are required during a setup.
Vise Model | Large V-Type Jaw Diameter Range (mm) | Small V-Type Jaw Diameter Range (mm) |
GT100 | 6–16 | 4–10 |
GT125 | 9–24 | 7–18 |
GT150 | 13–38 | 9–24 |
GT175 | 15–40 | 9–24 |
GT200 | 15–42 | 9–24 |
GT300 | 15–42 | 9–24 |
V-type jaws help stabilize cylindrical workpieces, such as round bars, pins, shafts and tubing, while reducing the risk of rolling during machining and setup.

To receive an accurate quotation, please send us your vise model, technical drawing, sample, target quantity, material requirement and application details.
The standard series covers GT100, GT125, GT150, GT175, GT200 and GT300 precision machine vises. For compatibility with another vise brand or model, please provide the jaw drawing, mounting dimensions or a physical sample for evaluation.
For shafts, cylindrical parts, round bars or tubing, choose the V-type jaw. Please refer to the diameter ranges listed above and confirm the diameter of your workpiece before placing an order.
Step jaws are used to clamp workpieces at different heights or provide extra machining clearance. They are especially useful for parts that require elevated positioning, multi-step clamping or access to more workpiece surfaces.
