BACHIN Rotary Table 90° 3″ Cross Slide Drill Press Vise
The BACHIN rotary table combines a compact 3″ cross slide with a 90° rotating work surface, ideal for precision milling and drilling tasks on small to mid-size machines. Its aluminum alloy construction emphasizes durability without excessive weight, while a vernier-style reading enhances angle accuracy during setup. With an adjustable X55 X Y travel (80 mm and 67 mm respectively) and a 1.5 mm ring offset, this vise provides repeatable positioning for light to medium-duty operations. The dual rotatable handles offer convenient front-to-back adjustment, and a robust screw mechanism maintains clamping stability during heavy cuts.
VEVOR Milling Vise 4 Inch
VEVOR’s 4-inch milling vise is designed for precision clamping on bench setups, combining a high-hardness iron body with a smooth, flat clamping surface. It’s built to withstand repeated use in demanding environments, featuring a powerful clamping force and a 360-degree swiveling base for flexible workpiece orientation. The precision screw delivers accurate parallelism and squareness, making it suitable for milling, drilling, and light index work where steady, repeatable holding power matters most.
VEVOR 6 Inch ACCU Lock Down Vise
This 6-inch ACCU Lock Down Vise from VEVOR emphasizes high stiffness and long-term service. Its jaw alignment is built for precision, and a robust screw mechanism ensures smooth operation without deformation. With a 6″ jaw width and a 5.9″ jaw opening, it accommodates larger workpieces while maintaining tight tolerances. The design focuses on minimizing runout and maximizing repeatable clamping force for milling, drilling, and light turning tasks in workshop settings.
VEVOR Rotary Table for Milling Machines 4”
The VEVOR 4-inch rotary table is designed for precise positioning, indexing, and clamping, especially in small milling machines. It features a 3.1″ chuck and a 360-degree graduated dial, with a 1:36 worm gear ratio enabling fine adjustments. This model supports curved surfaces, elongated holes, and precise drilling, suitable for automotive, mold-making, and general machining tasks. The table’s compact footprint makes it a practical addition for hobbyists and professional shops alike seeking reliable rotational indexing.
VEVOR 5-Inch 3 Jaw Chuck Dividing Head Set
The VEVOR 5-inch dividing head set combines a robust headstock with a 3-jaw chuck, enabling precise material division and indexing. Tiltable from 10 degrees below horizontal to 90 degrees vertical allows handling varied workpiece sizes. The set includes direct and interchangeable indexing plates to achieve different hole configurations, supporting accurate divisions for milling, drilling, and machining operations where repeatable angular placements are essential.
Buying Guide
Key purchase considerations when selecting a rotary or index vise for milling:
- Clamping force and stability: Look for heavy-duty cast iron or aluminum-aloy builds with minimal flex. A high clamping force reduces movement under load and preserves tolerances during milling or drilling.
- Rotation and indexing accuracy: A vernier or digital readout improves repeatability. Check the rotation range (0–90 degrees, full 360 degrees) and the presence of a precise dial or scale for indexing tasks.
- Jaw size and opening: Choose jaw width and opening that match your typical workpieces. A larger jaw can handle bigger stock, but smaller vises often offer tighter tolerances for small parts.
- Base and mounting: A 360° swiveling base provides flexibility in orientation, while a rigid base prevents drift. Ensure compatibility with your milling table and T-slot sizes.
- Material and finish: Hardened steel or high-grade aluminum alloys balance strength and weight. A smooth surface reduces marring of workpieces and eases clamping adjustments.
- Accessories and compatibility: Consider included chucks, jaws, or indexing plates. Ensure the unit fits your machine’s spindle, table size, and any required adapters.
- Maintenance and service: Look for brands offering replacement screws, jaws, and calibration references. Durable threading and corrosion resistance extend life in workshop environments.
In practice, the best choice depends on your typical workflow. For compact benches or small parts, a 3″ to 4″ rotary table with a swiveling base can deliver reliable indexing and angled cuts. For larger workpieces or heavy-duty milling, a 6″ ACCU Lock Down vise or a robust 6″ rotary table provides greater clamping stability and versatility. If you frequently perform precise divisions and repetitive angles, investing in a dividing head with interchangeable plates offers significant long-term value.
