SYJ-40-LD Manual 4-Inch Diamond Cut-off Saw with 5 Diamond Blades for Fast Material Sectioning
The SYJ-40-LD is engineered for efficient manual cutting of a variety of valuable and hard materials including rough crystals, ceramics, and metal rods. It is particularly suited for preparing samples quickly before subsequent lapping and polishing processes. This saw facilitates fast sectioning with a robust design that supports materials up to 6 inches in length and 40 mm in width.
Equipped with a 1/4 HP equivalent variable speed motor, the SYJ-40-LD delivers spindle speeds adjustable between 400 and 3250 RPM. This allows the use of ultra-thin diamond blades for precise and clean cuts. The saw housing is made from durable cross-linked polyethylene, which resists rust and requires only water for cooling, eliminating the need for oil-based lubricants.
Key Features
- Variable speed direct drive motor with speeds from 400 to 3250 RPM for versatile cutting control.
- Includes five 4″ diameter impregnated diamond blades, each 0.35 mm thick with a 1/2″ arbor.
- Maximum cutting depth of 25.4 mm (1 inch) and maximum sample width limited to 40 mm by the sample holder opening.
- Flat, removable saw housing for easy cleaning and trimming of oversized slabs.
- Sturdy 6″ x 10″ table surface for stable operation and sample support.
- Constructed from unbreakable cross-linked polyethylene to prevent rust and facilitate water-only cooling.
- Suitable for fast cutting of hard materials; not intended for precision cutting applications.

Typical Applications
Ideal for fast cutting of rough crystals, ceramic pieces, metal rods, and other hard materials prior to lapping and polishing. Suitable for laboratories and workshops requiring quick sectioning of samples without the need for ultra-precise cuts.
Configuration & Operating Notes
The standard package includes five impregnated 4″ diamond blades. The vise is not included as of September 2020 and must be sourced separately if needed. For cutting softer materials such as plastics or certain metals, optional 4″ silicon carbide (SiC) blades are available at extra cost. To extend blade life, sintered diamond blades and specialized lubricants like Lube-150 can be ordered separately. The saw housing is removable for cleaning and trimming oversized slabs. Use water only for cooling; oil is not required. For applications requiring higher precision, consider low-speed precision diamond saw models such as SYJ-150 or SYJ-160.
