Diamond sharpeners have a highly precise rotating disc and are harder than ceramic sharpening stones, making them less prone to dents. When combined with the high-speed rotation of an electric sharpener, they can sharpen various materials and specialized cutting tools (carving knives, carbide tools, tooth drill bits, etc.) and objects. They are long-lasting, produce little powder during sharpening, and leave minimal mess. From rough cutting to mirror finishing, one tool is all you need, significantly shortening the process for hobby crafts.
Comes with diamond sharpening stones of different grit sizes (#200, #800, #2000, #3000) for coarse, medium, fine, and finishing sharpening. You can use the different grit sizes to perform all stages from coarse to fine sharpening. No additional sharpening stones need to be purchased.
Equipped with a speed control knob and a forward/reverse rotation switch. Stepless speed adjustment from 0 to 4000 RPM is possible. Speed and rotation direction can be adjusted according to the blade material, grinding needs, and application.
The main body is made of one-piece molded aluminum, and its compact desktop size allows it to be placed on a small workbench or held in the hand for grinding. Four foot pads are attached to the bottom to prevent the machine from slipping and ensure stability during operation. Weighing only 1.1 kg, its lightweight design makes it convenient to carry to a home workshop or on the go.
This compact grinding wheel has a diameter of 50mm. It is suitable for sharpening various precision tools such as cemented carbide, tungsten steel, NC lathe tools, milling cutters, carving knives, ivory carving tools, seal carving tools, hobby tools - groove carving blades, watch screwdrivers, hand-carving knives, pneumatic carving knives, tweezers, screws, etc. It can also be widely for polishing wooden and bone prize items, seashells, needle tips, fishhooks, glass electrode needles and other needle heads, and for finishing small handmade DIY products. (2-inch (50mm) sandpaper can be attached to the back of the grinding wheel.) *Not suitable for sharpening large blades such as kitchen knives.
The "Mini Diamond Grinding Machine" is a compact yet powerful electric bench grinder featuring a set of four 2-inch (approximately 50mm) diameter diamond grinding wheels. Suitable for rough, medium, and finishing grinding, it's ideal for both home and professional use. Its grinding capabilities and functionality are designed to satisfy a wide range of users, from hobbyists to professional backup equipment. Main Unit x 1

*The grinding wheel can be easily replaced using the included tool.
Rotational speed control (speed control)
The rotation speed can be adjusted steplessly using the adjustment dial on the main unit. At low speeds, precision grinding with minimal heat effects is possible, making it ideal for high-quality blades and thin blades that cannot be hardened. At high speeds, material removal is quick, and chipping and reshaping of blades can be done in a short time.
Forward/Reverse Rotation Switch
Equipped with a dedicated switch to change the motor's rotation direction. By changing the rotation direction of the grinding wheel, you can choose to sharpen the blade on either side (double-edged or single-edged) or select a sharpening position that suits your dominant hand. The reverse function also helps reduce clogging of the grinding wheel, contributing to maintaining sharpening efficiency.
Suitable for dry polishing
Because it's a dry type that doesn't use water or oil, there's no liquid splashing during grinding, keeping the work environment clean. (Note: During dry grinding, the temperature rises due to friction from high-speed rotation.)
This product is not intended for continuous operation over long periods of time.
Always wear safety glasses while polishing to protect your eyes from flying dust. We also recommend using a dust mask if necessary.
Due to the nature of dry polishing, the blade edge temperature may rise with continuous use. Please take breaks as needed while polishing to prevent discoloration (burning) of the blade edge.
Always turn off the power and unplug the machine before changing the grinding wheel.
