Answer
Laser vs Waterjet vs CNC for a Bracket: Which Route to Quote
Pick the route by the bracket’s features, not by habit. Here is how each one behaves and what to send.
For a flat bracket, laser cutting is the default route in sheet, with the profile tolerance set in the quote. Waterjet cuts cold, no heat-affected zone, and handles far thicker plate with a wider kerf. CNC milling is quoted at ±0.005 in typical, with called-out features quoted from the print, but cuts the bracket from solid. When a bracket needs one machined feature, a reamed hole or a flat face, laser cut plus machining as one order beats a fully milled bracket.

What each process does to a flat bracket
A laser melts or vaporizes a narrow path through sheet, a waterjet erodes it with abrasive in water, and a mill removes everything that is not the bracket. Wikipedia’s laser cutting article at en.wikipedia.org/wiki/Laser_cutting puts kerf widths as small as 0.004 in (0.10 mm), a small heat-affected zone, and an as-cut surface roughness of 125 to 250 microinches. The result is a flat blank with square holes and slots, a slight edge taper on thick plate, and a heat-tinted or lightly hardened skin on steel and stainless. For a clearance-hole bracket in 0.125 in 5052 or 0.187 in A36, that is the whole job.
A waterjet leaves a cold, sandblast-textured edge and a much wider slot. The water jet cutter article at en.wikipedia.org/wiki/Water_jet_cutter gives an abrasive kerf of 0.04 to 0.05 in (1.0-1.3 mm), a taper of less than 1 degree on most cuts, and no heat damage to the surface or edges. Milling makes none of those compromises but pays for them differently: the bracket is cut from plate or bar, so material removal and setups drive the price, and the third dimension is free. Pockets, counterbores, a faced mounting pad and a reamed bore all come out of the same fixture.
Where laser stops and waterjet or plasma takes over
The laser route has a practical ceiling on thickness, and the print decides where a given bracket sits against it. Name the material and thickness on the print, and the quote says which route it takes. As a reference, Wikipedia notes that common industrial systems of 1 kW or more cut carbon steel from 0.51 to 13 mm (0.020 to 0.51 in). Above that, edge quality falls off faster than the numbers suggest: more taper, more dross on the bottom edge, and slower cutting that shows up in the quote.
Waterjet has no such ceiling in practice. The same Wikipedia article puts waterjet capacity at up to 6 in (150 mm) of metal, so a 1.0 in steel or 1.5 in aluminum bracket blank is a waterjet part, cold-cut, with the taper controlled by slowing the cut or tilting the head. Plasma is the third option for thick carbon steel where the edge will be machined or welded anyway; it is fast and rough, and a print that needs a finished edge should not expect one from plasma. Heat-sensitive sheet is the other waterjet case: G10/FR4 chars under a laser, so it goes to waterjet rather than the laser at whatever thickness the print names.
Heat-affected zone and edge finish, side by side
The laser edge is hot; the waterjet edge is not. On steel and stainless the laser leaves a thin heat-affected zone and an edge whose color depends on the assist gas: bright under nitrogen, oxidized when oxygen reaches the cut, and it may still show gold or blue tint on stainless. That edge matters when a tap, reamer or weld follows the cut, and when the part is a bearing or wear surface. On 5052 and 6061 the effect is small and mostly cosmetic. The waterjet edge is matte and slightly rough from the abrasive, with no hardness change, which is why heat-treated and pre-hardened plate, laminates and anything that will be welded heavily often go to waterjet.
A mill leaves a machined surface, typically the best of the three where it counts, and it is the only route that gives you a flat face perpendicular to a bore. Edge finish, though, is rarely the deciding factor on a bracket. Most brackets bolt to something and are painted or anodized; a deburred laser edge under powder coat looks like a machined edge under powder coat. Where the edge is the working surface, a wear strip or a gib, that is a machined part, and the custom CNC brackets page covers which alloys are worth machining from solid.
How tolerance works on each route
Laser and waterjet land close together on a cut profile; milling starts from a general number and adds called-out features on top of it. For a laser-cut or waterjet-cut bracket the quote states the tolerance used on the profile. CNC-machined metals are quoted at ±0.005 in typical on size and location, with called-out features quoted from the print. ISO 2768 is the usual default when a print gives no tolerance. As a reference for the process itself, the Wikipedia water jet article gives accuracy down to 0.005 in (0.13 mm) and repeatability to 0.001 in.
What those numbers do not say is as important. Both cut processes leave some taper on thick plate, so a laser-cut hole in 0.500 in plate is not the same size through its full depth. A milled or reamed hole is, and a reamed dowel hole to a H7 fit or a bore called out to ±0.0005 in on the print is a machined feature by definition. ASME Y14.5 callouts for position and perpendicularity belong on the print when the bracket locates something; the laser cut tolerances page explains how a laser tolerance is written on the print, and CNC machining tolerances covers the machined side.
When the bracket needs a machined feature
One reamed hole does not make a bracket a milled part. The usual answer is laser cut plus machining as one order: the profile and clearance holes are cut from sheet, then the two locating holes are reamed, the counterbore is added, or the mounting face is milled flat, and the finished bracket is inspected once against the print. That keeps the material removal to the feature that needs it. The tapped and machined as one order page covers how to draw it: leave the machined holes undersize on the DXF, call the finish size and tolerance on the PDF print, and mark the datum face.
A fully milled bracket makes sense when the third dimension is the point: a stepped or angled mounting pad, pockets to save weight, a bore whose axis is not perpendicular to the sheet, or thick stock in a shape that a cut blank cannot become. Those go through CNC milling as machined parts, and a milled bracket runs on the machined-parts schedule, 4-6 weeks standard. Laser routes carry no such number here: lead time on a laser-cut bracket is quoted per job, rush available. The custom CNC brackets page shows how both routes are drawn and quoted.
Cost drivers, a decision list, and what to send
Price on a bracket follows material removal, setups, thickness and quantity, in roughly that order. A cut process removes only the kerf, so material cost is close to the blank weight; a milled bracket pays for the plate it starts from and the time to turn most of it into chips. Each secondary operation adds a setup, spread thinner across 50 pieces than across 1. Thicker sheet cuts slower on a laser and much slower on a waterjet. None of that produces a figure without a print, which is why the machining cost page talks drivers only.
By feature: clearance holes and a flat profile in sheet, quote laser. The same in plate thicker than the laser route handles well, or in heat-sensitive stock, quote waterjet. Any reamed hole, tapped hole to a depth, counterbore, flat face or perpendicularity callout, quote laser cut plus machining as one order. Pockets, angled pads, non-perpendicular bores or thick stock in a 3D shape, quote milled. For the cut routes send a DXF of the profile plus a PDF print with material, grade, thickness, quantity and every callout; the laser file guide lists them. For a milled bracket send a STEP plus the PDF. The laser-cut parts hub explains the one-order route; the quote form takes any file type and a person answers in 24-48 hours.
Questions
Before you send a job.
01 Is laser cutting or waterjet more accurate for a bracket?
Profile tolerances are close, and for either cut the quote names the number. The laser holds a tighter profile in thin sheet because its kerf is narrower; the waterjet wins on thick plate because it has no heat-affected zone and its taper can be controlled. As a reference, the Wikipedia water jet article gives waterjet accuracy down to 0.005 in (0.13 mm). Neither holds a fit through a hole; that is a machined feature.
02 At what thickness should a bracket go to waterjet instead of laser?
There is no single number to design to: the thickness on the print decides it, and the quote says which route it takes. As a reference, Wikipedia puts common industrial lasers of 1 kW or more at carbon steel up to about 0.51 in (13 mm). Past that, edge taper and bottom-edge dross grow and the cut slows, so a 1.0 in steel bracket blank is a waterjet part. Heat-sensitive stock changes the answer at any thickness: G10/FR4, pre-hardened plate and laminates go to waterjet even at 0.125 in.
03 Does the heat-affected zone from laser cutting matter on a bracket?
Usually not on a painted or anodized clearance-hole bracket in 5052, 6061 or mild steel. It matters when a tap or reamer follows the cut in stainless or in pre-hardened steel, when the edge is a wear or bearing surface, or when the bracket will be welded heavily. In those cases quote waterjet, or quote laser cut plus machining so the critical edge or hole is machined clean.
04 Can a laser-cut bracket have a reamed hole or a machined face?
Yes, as one order. The profile is cut from sheet with the critical holes left undersize, then the dowel holes are reamed to the print, a counterbore or flat face is milled, and every finished bracket is inspected against your print before it ships. The print carries the finish size, tolerance and datum; the DXF carries the profile and the undersize holes.
05 When is a fully milled bracket the right answer?
When the shape is three-dimensional: a stepped or angled mounting pad, weight-saving pockets, a bore that is not perpendicular to the sheet, or thick stock in a form a cut blank cannot become. A milled bracket is quoted as a machined part, on the machined-parts schedule. A flat bracket with one or two machined features is almost always cheaper as laser cut plus machining.
06 What should I send to get all three routes quoted?
A PDF print with material and grade, thickness, quantity, and every hole, thread, fit and finish callout, plus a DXF of the flat profile. If a STEP exists, include it. Say in the notes that you want the route recommended; the quote comes back in 24-48 hours from a person who has read the print, naming the route and why, and listing anything on the print that cannot be made or inspected as drawn.
