An overhead router carries a high-speed spindle on an arm above the table and plunges it into the workpiece from above, which is how template work, lock and hinge mortises, recesses, slots and internal cut-outs are cut in doors and panels. This category holds 2 NETMAK machines: the FRS 900, with 910 mm between cutter and column on a 790 x 970 mm table at 630 kg, and the FRS 1250, which extends that reach to 1250 mm on a 960 x 1220 mm table at 850 kg. Both are supplied by quotation. Compare the two below and request a quote.

How to choose an overhead router

Reach decides the choice between these two machines, and almost nothing else does. The distance from cutter to column sets how far into a panel the spindle can work: the NETMAK FRS 900 offers 910 mm, the NETMAK FRS 1250 offers 1250 mm. Measure the deepest point you must reach on your largest part before comparing anything else. A lock mortise on a door edge is within reach of either machine, but a recess in the middle of a full door leaf or a wide panel is the case the FRS 1250 exists for. Spindle and travels otherwise match: both machines run 9000-18000 rpm on a 12-14 mm collet.

Table size and mass

Table size follows reach, and mass follows table size. The FRS 900 carries a 790 x 970 mm table in a 630 kg frame, while the FRS 1250 carries 960 x 1220 mm at 850 kg. Those 220 kg are not a disadvantage: mass is what keeps an overhead router from moving as the spindle plunges into hardwood, and a bigger table supports a door leaf that would otherwise need outboard stands. The cost is floor space and a heavier lift into position, so confirm access and floor loading in your workshop before specifying the FRS 1250.

Pneumatic head movement

Plunge control is what makes an overhead router a production machine rather than a hand tool on a stand. The FRS 900 raises its head pneumatically, so the operator’s hands stay on the workpiece and each plunge repeats at the same rate instead of depending on how hard the lever was pushed. Pneumatic operation also means the machine needs compressed air alongside its electrical supply – plan the compressor and the airline into the installation, not after it.

Power supply and installation

Plan the electrical supply before delivery. The FRS 900 is specified with a 3.2-4 HP motor, a rating that belongs to a three-phase installation in nearly every workshop, and both machines run spindle speeds of 9000-18000 rpm, which implies a frequency-controlled or high-frequency spindle drive rather than a simple switch. State the supply available in your shop – and whether you have compressed air – when you request a quote, so the correct configuration is quoted rather than corrected on site.

Floor space and extraction

Allow space around an overhead router equal to the largest panel you will place on it, not to the table. A 960 x 1220 mm table on the FRS 1250 will hold a door leaf, but the operator still has to turn that leaf, so leave clear working area on at least three sides. Extraction should be planned with the machine: routing at 9000-18000 rpm throws fine dust at head height beside the operator, and a hood connected to a chip extractor is the only practical control. Air lines, ducting and the electrical feed should all reach the same position.

Tooling and cost drivers

Budget cutters, collets and templates alongside the machine. Both NETMAK overhead routers take 12-14 mm collets, so tooling is straightforward, but production work depends on the template and clamping arrangement far more than on the router itself: a lock-mortise jig, hinge templates and reliable workpiece clamping decide cycle time and repeatability. Across this pair the price driver is reach, table size and frame mass – 910 mm and 630 kg against 1250 mm and 850 kg – plus tooling, delivery and installation. Because both machines are quoted rather than sold at a published list price, describe the parts you machine and we will recommend the FRS 900 or the FRS 1250.

როგორ ავირჩიოთ

Cutter-to-column reach
910 mm on the FRS 900 covers door edges and frame parts; 1250 mm on the FRS 1250 is what reaches into the middle of a full door leaf or a wide panel.
Table size
790 x 970 mm on the FRS 900 against 960 x 1220 mm on the FRS 1250 - the larger table supports a door leaf without outboard stands.
Machine mass
630 kg versus 850 kg; the extra mass steadies deep plunges in hardwood but demands floor space and access for the lift-in.
Spindle speed 9000-18000 rpm
Identical on both machines - run the low end for large-diameter cutters and hardwood, the high end for small cutters and clean template edges.
Collet 12-14 mm
Common to both models, so a cutter set moves between them; budget cutters and collets with the machine.
Compressed air
Pneumatic head raise on the FRS 900 needs a compressor and an airline at the machine position - plan it with the installation.
Motor rating
The FRS 900 is specified at 3.2-4 HP, a three-phase-class installation in practice; confirm the supply on your quotation.

ხშირად დასმული კითხვები

Should I choose the NETMAK FRS 900 or the FRS 1250?
Choose between the FRS 900 and the FRS 1250 on reach. The FRS 900 gives 910 mm from cutter to column on a 790 x 970 mm table at 630 kg, which covers lock and hinge mortises, slots and template work along the edges of doors and frame parts. The FRS 1250 gives 1250 mm on a 960 x 1220 mm table at 850 kg, which is what you need to reach a recess in the middle of a full door leaf or a wide panel. Spindle speed of 9000-18000 rpm and the 12-14 mm collet are the same on both.
What is the difference between an overhead router and a spindle moulder?
An overhead router carries the spindle above the workpiece on an arm and plunges down into it, so an overhead router cuts mortises, recesses, slots and template shapes anywhere on a panel. A spindle moulder carries the cutter below, in the table, and shapes an edge as the workpiece passes a fence, which is what mouldings, rebates and cope-and-stick frame joints require. Most joineries end up with both machines because neither does the other's work.
What power supply and services does an overhead router need?
An overhead router needs a three-phase-class electrical supply in practice - the FRS 900 is specified with a 3.2-4 HP motor - plus compressed air, because the head is raised pneumatically on the FRS 900. Spindle speeds of 9000-18000 rpm on both machines mean a controlled spindle drive rather than a simple on-off switch. State the voltage available in your workshop and whether you have a compressor when requesting a quote, so the correct configuration is specified.
How much space and extraction does an overhead router need?
An overhead router needs clear space equal to the largest panel you place on it, on at least three sides, because the operator turns the workpiece on the table rather than feeding it through: the FRS 1250 with its 960 x 1220 mm table will hold a door leaf, but that leaf still has to be rotated. For extraction, routing at 9000-18000 rpm throws fine dust at head height next to the operator, so connect a hood at the spindle to a chip extractor and run the ducting, the airline and the electrical feed to the same position.
What does an overhead router cost?
The cost of an overhead router is driven by reach and frame size first - 910 mm and 630 kg on the FRS 900 against 1250 mm and 850 kg on the FRS 1250 - then by the cutter and collet package, the templates and clamping you specify, delivery to your workshop and installation and commissioning. Both NETMAK overhead routers are sold by quotation rather than at a published list price, so send us the parts you machine and the reach you need and we will quote the appropriate model.
What tooling do I need besides the machine?
Besides the overhead router itself, budget cutters and collets - both the FRS 900 and the FRS 1250 take 12-14 mm collets, so one cutter set serves either machine - and, more importantly, the templates and clamping. A lock-mortise jig, hinge templates and secure workpiece clamping decide cycle time and repeatability on an overhead router far more than the machine specification does, so specify them at quotation stage rather than improvising later.
