110mm Horizontal/Vertical Rotary Table with Disengageable Worm Gear
The 110mm horizontal/vertical rotary table combines compact dimensions, controlled 90:1 gearing and fast free rotation for precise milling, drilling and angular-positioning operations.
Use it horizontally for circular machining and bolt-hole patterns or mount it vertically for indexing, slotting and operations around a horizontal axis. Its 110mm table, 2MT center hole and three 11mm T-slots provide a versatile workholding platform without consuming the space required by a larger rotary table.
Why Choose This 110mm Rotary Table?
This model is designed for machinists who need more control than basic manual positioning but still want fast setup adjustments. The worm gear can be easily disengaged, allowing the table to rotate freely during initial positioning. Re-engage the gear to make controlled angular adjustments using the handwheel and vernier scale.
- Use horizontally or vertically
- Compact 110mm precision-positioning platform
- 90:1 gear ratio for controlled table movement
- Disengageable worm gear for rapid free rotation
- 10-second vernier for fine angular settings
- Full 360° graduated table
- 2MT center hole for compatible centers and setup tooling
- Three 11mm T-slots for flexible workholding
Fast Positioning and Fine Angular Control
The 90:1 worm-gear ratio means that one complete rotation of the handwheel moves the table 4°. This predictable movement simplifies calculations for many common angular and indexing setups.
The table is graduated through a complete 360°, while the 10-second vernier supports finer settings than the primary graduation scale alone. This combination is useful when machining arcs, radial features and precisely positioned holes.
Disengage the Worm Gear for Free Rotation
Setting up a workpiece does not always require slow geared movement. The easily disengaged worm gear allows the operator to rotate the table freely to reach an approximate position quickly.
Once the workpiece is near the required angle, the worm mechanism can be re-engaged for controlled final positioning. This helps reduce setup time during jobs that require frequent or significant angular changes.
Horizontal and Vertical Machining Capability
In the horizontal position, the rotary table is suitable for circular milling, curved slots, radial drilling and machining features around a vertical axis.
In the vertical position, its 86mm center height allows workpieces to rotate around a horizontal axis. This configuration is useful for angular indexing, end machining and compatible tailstock-supported work.
| Mounting Position | Typical Operations |
|---|---|
| Horizontal | Arcs, circular profiles, radial holes and bolt-circle patterns |
| Vertical | Angular indexing, end features, slots and circumferential operations |
Compact 110mm Table for Smaller Machine Setups
The nominal 110mm table diameter provides useful clamping space while maintaining a compact footprint. Its horizontal overall height is only 80mm, helping preserve the working distance between the machine table and spindle.
With a listed weight of 19.55 lbs, the unit offers a practical balance between setup stability and portability for machine shops, maintenance departments, prototype work and compact milling equipment.
Three 11mm T-Slots for Workholding
Three equally positioned T-slots provide mounting points for compatible clamps, fixtures and workpieces. Each slot has a published width of 11mm, approximately 7/16″.
The 2MT center hole can accept compatible Morse-taper centers and alignment tooling. Verify all chuck adapters, mounting plates, centers, clamps and fasteners separately before ordering.

Compatibility Checklist Before Ordering
Confirm the following dimensions against your machine and intended setup:
- Available machine-table space for the 280mm overall handle length
- Spindle clearance with the table mounted horizontally
- 86mm center height when mounted vertically
- Machine load capacity for the table, fixture and workpiece
- Compatibility with the 2MT center hole
- Compatibility with the three 11mm T-slots
- Required chuck, adapter plate, clamps or tailstock
Chucks, adapter plates, dividing plates, tailstocks and clamping accessories are not specified as included. Purchase decisions should be based on the listed components and specifications.
Setup Tips for Better Machining Results
Install the rotary table on clean, undamaged machine surfaces and secure it with a rigid clamping arrangement. Indicate the rotary axis relative to the machine spindle before performing precision work.
When using the worm drive, approach final angular positions from the same direction whenever possible to reduce the influence of backlash. Use suitable cutting parameters, minimize workpiece overhang and always follow established shop-safety procedures.
Frequently Asked Questions
What makes this rotary table different from a standard 4-inch model?
This model has a nominal 110mm table, 90:1 gearing, three 11mm T-slots and a disengageable worm mechanism. These characteristics position it as a compact metric-oriented table with both rapid free rotation and fine geared adjustment.
Can the table be used vertically?
Yes. It can be mounted horizontally or vertically. The published center height in the vertical position is 86mm.
How far does the table move with one handwheel rotation?
One complete handwheel rotation moves the table 4°, based on the 90:1 gear ratio.
Can the table rotate without using the handwheel?
Yes. The worm gear can be disengaged to permit free rotation during initial positioning. It should be correctly re-engaged before using geared angular adjustment.
Does the table accept Morse taper tooling?
Yes. The center hole has a No. 2 Morse taper, commonly identified as 2MT or MT2. Confirm the dimensions of any center or accessory before installation.
