A mini vertical milling slide is the most direct way to add milling capability to a compatible mini lathe; a fly cutter and boring-head set can add useful cutting operations when the machine and tooling match. The products below are accessories, not complete lathe-and-mill machines. The ASSORTS slide is best suited to owners of specified 7 x 14 mini lathes, while the boring-head sets and fly cutter serve milling setups with matching connections.
| Product | Best For | Key Detail |
|---|---|---|
| ASSORTS Mini Vertical Milling Slide | Compatible 7 x 14 mini lathes | Slide, vise, and mounting plate |
| ASSORTS Fly Cutter | Facing and surface finishing | 75 mm head with replaceable insert |
| TINVHY 2-Inch Boring Head Set | Adjustable boring on R8 setups | Micrometer lead screw |
| iCarbide 2-Inch Boring Head Set | Boring with included bars and inserts | R8 arbor and six bars |
| iCarbide 3-Inch Boring Head Set | Larger boring-tool package | R8 arbor and six bars |
ASSORTS Mini Vertical Milling Slide
Best for: Owners of a compatible 7 x 14 mini lathe who want a dedicated vertical slide for milling-style work. The package includes a 2-inch steel vise and a base plate designed for direct mounting on the cross slide rest of the specified mini-lathe size.
The 90 x 50 mm fixed base is intended to provide a stable mounting platform. The product description also lists graded cast iron construction, ground working surfaces, a painted body, and a chrome-plated handle. It is the most directly relevant choice here for adding a milling slide to a small lathe.
Limitation: The listed mounting description specifies a 7 x 14 mini lathe. Check your machine’s slide, T-nut, and bolt arrangement before choosing it; compatibility with other lathes is not established by the supplied details.
ASSORTS 3-Inch Fly Cutter
Best for: A milling setup that needs a single-edge tool for facing and surface finishing. The cutter has a 75 mm head, a ground 3/4-inch straight shank, and an indexable holder with a replaceable carbide insert.
A fly cutter uses one cutting edge, and the listed product features identify fine surface finish as a reason to choose this tool over many face mills. It may suit a buyer assembling accessories around a milling slide, provided the machine accepts its shank and has suitable clearance.
Limitation: The listed shank is 3/4 inch straight. Confirm that your holder can accept it. The product information does not specify machine compatibility or cutting parameters.
TINVHY 2-Inch R8 Boring Head Set
Best for: Buyers with an R8-compatible milling spindle who want an adjustable boring head and carbide bars in one set. The head measures 2 inches, the boring-bar hole is 1/2 inch, and the listed maximum offset is 5/8 inch.
The set’s micrometer lead screw is described as providing 0.0001 direct-reading adjustment. Its steel construction is specified as balancing hardness and toughness. These details make it a useful option to compare when controlled boring adjustments matter.
Limitation: The R8 shank and 1/2-inch bar size are essential fit requirements. Verify the spindle and bar dimensions before purchase; an R8 tool is not automatically compatible with every lathe milling attachment.
iCarbide 2-Inch R8 Boring Head Set
Best for: Milling setups that need an R8 arbor, a 2-inch boring head, and a group of 1/2-inch-shank boring bars. The package lists six bars and included inserts, including TBGT 06, TPGT 09, and TPCT1103 types.
Compared with the TINVHY set, the supplied details emphasize the included tooling rather than a micrometer lead-screw accuracy figure. Choose this set if the listed assortment of bars and inserts fits your planned work and you want those components packaged together.
Limitation: The product description does not give the same adjustment-accuracy figure listed for the TINVHY set. Check the included bar and insert specifications against your machining needs.
iCarbide 3-Inch R8 Boring Head Set
Best for: Buyers comparing a larger boring head with an R8 arbor and a six-piece set of 3/4-inch boring bars. The listing also includes inserts identified as TBGT 06, TPGT 09, and TPCT1103.
Choose this set over the 2-inch iCarbide option when the 3-inch head and larger listed bar shank better match the intended milling setup. It was selected to represent a larger-format boring package among the supplied options.
Limitation: Confirm that your spindle accepts an R8 arbor and that the 3/4-inch bars suit the head and job. The listing does not establish suitability for a particular lathe milling attachment.
Buying Guide: Choosing Lathe Milling Accessories
Will the accessory mount to your lathe?
Start with the machine’s mounting geometry. The mini vertical slide is described for direct mounting on a 7 x 14 mini lathe cross slide using T-nuts and bolts. Compare your machine’s dimensions and mounting points with the product details rather than assuming that similarly sized lathes share a fit.
Does the spindle connection match?
Boring heads in this selection use R8 arbors. That connection must match the receiving spindle or holder. The fly cutter instead lists a 3/4-inch straight shank, so check its holder separately. Connection size is a key compatibility check, not a minor detail.
Which tool matches the operation?
- Choose a vertical slide when the goal is to position work for milling-style operations on a compatible mini lathe.
- Choose a fly cutter for single-edge facing work when the shank and available clearance suit the setup.
- Choose a boring head for adjustable boring, comparing head size, bar diameter, included bars, and adjustment details.
What should you compare in boring-head sets?
Compare the arbor, head size, bar-hole diameter, bar quantity, and included inserts. The TINVHY listing specifies a micrometer lead screw with 0.0001 direct-reading accuracy. The iCarbide listings focus on their included bars and inserts. These descriptions provide different comparison points, so select based on the stated requirements of your work.
Frequently Asked Questions
Can these products turn a standard lathe into a milling machine?
Not by themselves. The slide is an accessory described for a specific mini-lathe format. The other products are cutting or boring tools that require a compatible machine, holder, and setup.
Which listed product is most directly intended for a mini lathe?
The ASSORTS mini vertical milling slide is the most direct match because its description specifies mounting on a 7 x 14 mini lathe cross slide.
Do the boring heads use the same bar size?
No. The 2-inch sets list 1/2-inch bars, while the 3-inch iCarbide set lists 3/4-inch bars. Confirm the size before ordering.
Is an R8 boring head compatible with every lathe?
No. An R8 arbor requires a matching R8 spindle or holder. Check the machine’s specifications before selecting an R8 tool.
