Precision Matthews PM-728VT guide to specs, setup, and buyer considerations
What the Precision Matthews PM-728VT is designed to do
The Precision Matthews PM-728VT is a bench-type vertical milling machine for serious home shops, prototype rooms, repair benches, and small machine shops that need more rigidity and travel than a mini mill, but do not have the space, power, or handling equipment for a full-size knee mill. Based on Precision Matthews product data reviewed on October 9, 2026, the PM-728VT combines a square-column cast-iron structure, R8 spindle, 1 hp brushless DC motor, belt drive, variable spindle speed, and a 7 x 28 in table.
The buying decision is not only about whether the machine can cut the required materials. Buyers also need to confirm that its travel, 380 lb packaged unit weight, 110 V power requirement, 4000 rpm top speed, and freight delivery requirements fit the work, the shop layout, and the available lifting plan.

Verified specifications that shape the buying decision
Published specifications are most useful when they are tied to real shop constraints. The PM-728VT is a bench mill, but its weight and travel put it above many lighter benchtop machines. Precision Matthews lists the machine as made in Taiwan, with Taiwan also shown as the country of origin in its shipping data. The company lists a five-year warranty, although its FAQ language describes warranty support as parts-focused rather than a repair-service commitment. Buyers should review the current warranty terms before ordering.
| Specification area | Published PM-728VT data | Why it matters |
|---|---|---|
| Mill type | Bench type vertical mill | Requires a strong stand, bench, or dedicated base rather than a knee-mill footprint. |
| Table size | 7 x 28 in | Determines vise size, fixture capacity, and part support. |
| Travels | X 19 in, Y 10 in, Z 16 in, quill 3 in | Sets the practical envelope for parts, fixtures, and tool changes. |
| Spindle | R8 taper, 7/16-20 drawbar thread | Supports a common tooling ecosystem for small mills and knee mills. |
| Motor and drive | 1 hp brushless DC motor, belt drive, variable speed | Reduces gear-change complexity and supports speed changes during varied work. |
| Speed range | 75 to 4000 rpm on current product data | Useful for small cutters and aluminum, but not a substitute for true high-speed machining. |
| Cutting capacity | Drilling 0.75 in, end milling 1 in, face milling 3 in | Indicates intended capability, not an invitation to run maximum cuts in all materials. |
| Power | 110 V, single phase, 60 Hz, 20 A circuit, NEMA 5-15P plug | Attractive for garage and small-shop users without three-phase service. |
| Shipping weight | Approximately 440 lb crated | Requires a plan for liftgate service, pallet movement, and final placement. |
One specification needs careful reading. The manual summary available through ManualsLib describes variable spindle speed from 100 to 4000+ rpm, while the current Precision Matthews product specification table lists 75 to 4000 rpm. For purchasing and publishing decisions, the current product page should be treated as the active sales reference. Owners should still follow the manual supplied with their specific machine.
Rigidity, travel, and spindle choices in practical use
The PM-728VT’s appeal comes from its combination of weight, square-column construction, and travel. Precision Matthews lists the machine at about 370 lb without the stand. The current product table lists 380 lb for the unit in packaging and 440 lb shipping weight. In a compact mill, mass helps resist vibration, but it does not make the machine behave like a full-size toolroom mill. Tool sharpness, cutter diameter, stickout, vise rigidity, setup quality, and feed discipline still drive surface finish and tool life.
The 19 in X-axis travel and 10 in Y-axis travel are generous for this class. Y travel is especially important because many benchtop mills become tight front-to-back once a vise, parallels, edge finder, and cutter clearance are included. The 16 in Z-axis travel and 16.25 in spindle-to-table maximum also help with tool changes and taller setups, although long drills, boring heads, and drill chucks can use up vertical space quickly.
The R8 spindle taper is a practical advantage. R8 tooling is widely available, familiar to many machinists, and suitable for collets, end mill holders, drill chucks, fly cutters, and boring heads. A 4000 rpm top speed is adequate for many steel and aluminum operations with moderate-size cutters. Very small carbide end mills, engraving tools, PCB work, or high-speed aluminum strategies may require more spindle speed than the stock head provides. That does not make the machine unsuitable; it defines the work range it fits best.
DRO, accessories, and configuration choices
Precision Matthews lists a quill or spindle depth DRO as standard equipment. That is useful for drilling, spot-facing, and controlled downfeed work, but it is not the same as a full three-axis table and head DRO. The optional three-axis DRO choices are listed as MX-100M numerical or MX-200M graphical displays. Precision Matthews notes that both use the same scales and differ by display type. The company also states that the third axis on the optional three-axis DRO reads head movement, not quill movement, so a buyer who orders the full DRO setup can read head position and quill movement through separate measuring systems.
The accessory package affects the real purchase price and the first setup. Standard accessories listed by Precision Matthews include a chip tray, way cover set, drawbar, R8 spindle taper, quill depth DRO, and spindle locking wrench. Optional equipment includes a dedicated stand with leveling feet and factory-installed DRO choices. The stand listing describes a 32 in stand height and a mill table surface height of 40.5 in when mounted on that stand, with a stand net weight of 100 lb. That working height will suit many standing users, but buyers should still consider posture, lighting, chip control, and whether the machine will be used seated or standing.
An X-axis power feed is also offered for the PM-728VT platform. Precision Matthews describes it as a bolt-on Align power feed kit made to fit the PM-728VT, PM-833T, and PM-940TV family, with variable speed control, rapid traverse, table stops, and no drilling requirement. For repetitive passes, facing, slotting, and improved surface finish, power feed can do more than save effort. It can help keep feed more consistent than hand cranking.
Shop setup, delivery, and footprint planning
With compact mills, the hidden issue is often logistics rather than cutting capacity. Precision Matthews lists a machine footprint of 30 in deep, 41 in wide across the X-axis, and 44.5 in high without the stand. With the optional stand, the listed height is 76.5 in. These figures are minimum clearance references, not the full working envelope. A practical installation also needs room for table travel, handwheel access, tool changes, chip cleanup, lighting, coolant or mist decisions, and safe movement around the machine.
The current shipping data lists a skid size of 34 x 34 x 42 in and a shipping weight of about 440 lb. That is manageable for some small shops, but it still requires a clear handling plan. Depending on curbside unloading, driveway conditions, floor transitions, and final mounting height, a pallet jack, engine hoist, gantry, forklift, or other rated lifting method may be needed. The PM-728VT manual also gives installation guidance involving lifting and stabilizing the headstock. Those instructions should be followed with proper equipment and a second person when required.
Power planning is simpler than it is with industrial three-phase equipment. The current product data lists 110 V single-phase power, 60 Hz, a 20 A circuit requirement, and a NEMA 5-15P plug on an approximately 5 ft cord. Buyers should still check the electrical details before installation. A suitable circuit, proper grounding, adequate lighting, and keeping cords clear of chips and coolant are basic requirements for a safer, more reliable setup. See also: Materials.
Availability and pricing notes as of October 2026
Machine-tool pricing and availability can change quickly, so this section should be read as a dated snapshot rather than permanent information. On the Precision Matthews product page reviewed on October 9, 2026, the PM-728VT was shown with a listed price range of $3,699.99 to $4,899.99 depending on configuration. The same page showed the base machine and both DRO configurations as available on backorder, with a lead-time note dated September 29, 2026 and an estimated arrival of mid-to-late October 2026 for the PM-728VT and both DRO-equipped variants.
The page also described flat-rate freight shipping in the 48 U.S. states and optional liftgate service. Those costs and terms are order-specific and should be verified at checkout because accessories, delivery location, inside delivery requests, or carrier limitations can change the final logistics plan. For buyers outside the contiguous United States, Precision Matthews states that Hawaii, Alaska, Puerto Rico, and international shipments need to be quoted by the sales team.
Where the PM-728VT fits and where it has limits
The PM-728VT fits users who want a compact manual mill with meaningful travel, common R8 tooling, variable speed, a heavier structure than entry-level mills, and the option to add a DRO and power feed. It is well aligned with small-part machining, tooling modifications, aluminum and steel work within reasonable depth-of-cut expectations, prototype brackets, model engineering, maintenance parts, and educational shop use.
It is less suitable for users who need production-level material removal, large workpieces, long-bed travel, built-in flood coolant systems, automatic tool changing, or CNC performance out of the box. Precision Matthews does publish ball-screw kit information for CNC conversion, but a conversion is a project, not just a specification choice. Users considering CNC should budget for motors, drives, controls, enclosure decisions, lubrication, backlash management, limit switches, and the time needed to commission and troubleshoot the system.
A fair way to evaluate the PM-728VT is to see it as a serious bench mill, not as a small knee mill replacement or a high-speed machining center. Within that frame, its published combination of 10 in Y travel, 4000 rpm top speed, R8 spindle, brushless belt drive, and 110 V power gives it a useful balance for many non-production shops.
Buyer checklist before placing an order
- Confirm current price, availability, and lead time because the October 2026 listing showed backorder status.
- Decide whether the base quill DRO is enough or whether the three-axis DRO should be ordered from the start.
- Measure the intended shop location for width, depth, height, table travel, and operator access.
- Plan how a 440 lb crated machine will move from curbside delivery to its final location.
- Verify that the shop has a suitable 110 V, 20 A electrical circuit.
- Choose a stand, bench, or base that can support the machine safely and resist vibration.
- Budget for a vise, collets, clamping kit, parallels, indicators, cutters, cutting fluid, and measuring tools.
- Read the manual before lifting, tramming, adjusting gibs, running the spindle, or changing belts.
Frequently asked questions
Is the Precision Matthews PM-728VT a mini mill?
No. It is a bench-type mill, but its published 370 lb machine weight without the stand, 7 x 28 in table, and 19 x 10 in X-Y travel place it above typical mini-mill territory. It is still compact compared with a knee mill.
Does the PM-728VT use R8 tooling?
Yes. Precision Matthews lists an R8 spindle taper and a 7/16-20 drawbar thread. That matters because R8 tooling is common and widely supported in small-shop milling.
Is a three-axis DRO necessary?
It is not strictly necessary, especially for basic manual work, but it is a valuable option for repeatability, layout work, hole patterns, and reducing counting errors. The standard quill DRO only measures spindle or quill downfeed, while the optional three-axis DRO covers the table and head movement.
Can the PM-728VT run on normal shop power?
The current product data lists 110 V, single phase, 60 Hz operation with a 20 A circuit requirement. That makes it easier to place in a garage or small shop than many three-phase industrial mills, but the circuit should still be verified before installation.
What is the main limitation buyers should understand?
The PM-728VT is capable for its size, but it remains a bench mill. It should be used with realistic cutter sizes, conservative setups, rigid workholding, and suitable feeds and speeds rather than treated as a full-size production machine.
