Packing: diamond wire saw and saw frame. If any parts are missing, please for assistance. Due to the thin cutting line, proper installation is required when used with a hand wire saw. When using a hand saw, apply uniform pressure. Avoid quick pulls or excessive force to prevent blade breakage. Uses: Suitable for cutting various gems and abrasives, marble, granite, glass, ceramics, wood, metal models, and other hard and brittle materials requiring high precision cutting. Efficient: Features fast cutting speed, minimal chips, narrow kerf, and smooth cutting surface, ideal for fine cutting applications. Note: Water must be applied during cutting to prolong abrasive life, as is characteristic of all abrasive materials. When using a hand saw, maintain consistent, even pressure. Do not pull back rapidly or apply excessive force to avoid damaging the blade. Due to the thin cutting line, ensure screws are properly tightened during installation in a manual wire saw. To prevent damage from excessive force, secure the blade firmly and ensure screws do not interfere with blade movement.
