Circular Saws, Cut-Off Machines & Diamond Cutting Solutions
Cutting wood, steel, tile, concrete, marble, and masonry requires very different machines and accessories.
This guide explains how DCA circular saws, cut-off machines, and diamond cutting discs fit different jobs—and how to choose the right cutting setup for the material.
SHOP DCA CUTTING TOOLS FIND YOUR CUTTING SETUP ↓A cutting tool should be selected around the material first and the machine second.
A large circular saw designed for timber is completely different from a 14-inch abrasive cut-off machine designed for steel. Likewise, the correct diamond disc for concrete may not be the best choice for tile or marble.
DCA's current KHM lineup covers these jobs with large circular saws, heavy cut-off machines, and several material-specific diamond discs.
Circular Saw vs Cut-Off Machine vs Diamond Disc
🪚 Circular Saw
A handheld circular saw is built around a rotating blade and guide base for controlled straight cutting.
Typical work:- Timber
- Plywood
- Boards
- Construction lumber
- Bevel cuts
⚙️ Cut-Off Machine
A stationary abrasive cut-off machine uses a large wheel and clamping base to make repeated metal cuts.
Typical work:- Round steel
- Angle bar
- Channel steel
- Flat bar
- Metal fabrication stock
💎 Diamond Cutting Disc
A diamond disc is an accessory rather than a complete machine. The disc must match both the power tool and the material.
Typical materials:- Concrete
- Wall materials
- Tile
- Marble
- Granite
DCA Circular Saws — Built for Straight, Controlled Cuts
Circular saws are especially useful when the cut must travel through a large sheet, board, or length of timber while maintaining a straight line.
Blade Diameter
Larger blades generally allow deeper cutting capacity. DCA's AMY02-235 uses a large 235mm / 9-1/4-inch blade.
Cutting Depth
Maximum depth depends on blade size and cutting angle. The AMY02-235 reaches up to 85mm at 90°.
Bevel Cutting
Adjustable bevel capability lets the saw make angled cuts rather than only perpendicular cuts.
DCA AMY02-235 Circular Saw 9-1/4" 2000W
The AMY02-235 is DCA's large handheld circular-saw option featured in this guide.
It is rated at 2000W, runs at 4100 RPM, uses a 235mm blade, and provides cutting capacities of 85mm at 90° and 60mm at 45°.
Best for: construction lumber, thick timber, boards, sheet cutting, and users who need deeper cuts.
VIEW AMY02-235 →Another DCA 9-1/4-Inch Option
KHM also lists the DCA AMY235 Circular Saw / Groove Cutter, rated at 1520W with 4100 RPM, up to 84mm cutting capacity, and a maximum 45° cutting angle.

For fabrication shops, contractors, and steel workers, a cut-off machine offers a more stable setup than hand-cutting every section of steel with a portable grinder.
DCA AJG04-355 Cut Off Machine 14" 2000W
The AJG04-355 is designed for fast cutting of round steel, channel steel, and similar metal profiles.
KHM currently lists it at 2000W, 3800 RPM, a 355mm / 14-inch wheel, and approximately 14kg net weight.
Best for: fabrication shops, steel contractors, repair workshops, and repeated stock cutting.
VIEW AJG04-355 →DCA AJG04-355B Cut Off Machine 14" Full Cover Guard
The AJG04-355B uses the same 2000W / 3800 RPM / 355mm cutting format but adds a full cover guard.
KHM describes the full-cover design as helping reduce metal sparks reaching the operator and surrounding jobsite area.
Best for: fabrication shops and workspaces where additional spark containment is particularly valuable.
VIEW AJG04-355B →Diamond Cutting Discs — Match the Disc to the Material
Diamond discs may look similar, but their rim design, bond, and intended material can differ.
DCA's current KHM range includes separate 4-inch options for wall material, tile, concrete, marble/granite, and ultra-thin cutting.
Segmented Rim
Provides separated cutting segments and is commonly used for construction-material cutting where aggressive removal and heat dissipation matter.
Continuous / Ultra-Thin Rim
Continuous or thinner rims can provide a more refined cut depending on the material and disc design.
Which DCA Cutting Setup Fits Your Work?
DCA #3 Diamond Tile Cutting Disc 4" Segmented
KHM lists this disc specifically for dry ceramic cutting.
Best for: compatible ceramic tile cutting where a material-specific diamond disc is required.
VIEW DCA #3 →DCA #4 Diamond Concrete Cutting Disc 4" Segmented
This segmented DCA disc is listed specifically for dry concrete cutting.
Best for: compatible concrete and construction-material cutting with the correct power tool.
VIEW DCA #4 →DCA #5 Diamond Marble Cutting Disc 4" Segmented
KHM lists the DCA #5 for dry granite and marble cutting.
Best for: compatible stone work, countertop materials, marble, and granite applications.
VIEW DCA #5 →DCA #8 Diamond Cutting Disc 4" Continuous
The DCA #8 is listed at 105 × 20 × 1.6mm and is described as an ultra-thin continuous cutting disc.
Best for: users looking for a thinner DCA diamond-wheel option, subject to matching the disc to the material and machine.

Choose the Cutting Tool by Material
The Machine and Blade Must Work as One System
A powerful cutting machine does not compensate for the wrong blade or cutting wheel.
Before cutting, always confirm:
- Machine wheel or blade diameter
- Arbor or bore compatibility
- Maximum accessory RPM
- Material suitability
- Wet or dry cutting requirement
- Correct guard installation
- Required cutting depth
Cut-Off Machine vs Angle Grinder for Metal
Use a Cut-Off Machine When…
- You make repeated straight cuts.
- The workpiece can be clamped to the base.
- You cut steel sections regularly.
- Workshop productivity matters.
Use an Angle Grinder When…
- The cut must be made in place.
- The material cannot easily be moved.
- Mobility matters.
- You also need grinding and finishing capability.

Cutting Safety Essentials
- Wear suitable eye and face protection.
- Use hearing protection where required.
- Keep guards correctly installed.
- Secure the material before cutting.
- Check blades and discs for cracks or damage.
- Confirm accessory RPM rating before use.
- Do not force a blade through the material.
- Keep sparks away from flammable materials.
- Use dust control where concrete, masonry, or stone creates hazardous dust.
- Never use a blade or disc on a material it is not designed to cut.

Final Verdict: Match the Cutting System to the Material
For timber and large sheet work, choose a DCA circular saw with the cutting depth and blade capacity your project requires.
For repeated steel fabrication, the 14-inch DCA cut-off machine provides a stable workshop cutting setup.
For concrete, tile, marble, granite, and wall materials, choose the correct DCA diamond disc rather than treating all diamond wheels as interchangeable.
The right cutting setup is always a combination of machine, blade, material, cutting depth, and safe operating speed.
