Double direction blades wood cutting blade

Technical Data

1. Materials & Processing: Most adopt high-quality steel bodies such as 75Cr1 or SKS – 51, with tungsten carbide (TC) tips brazed on; some jigsaw variants use 8% cobalt bimetal. High – frequency welding or laser welding is used for tip fixation, and the blade body undergoes quenching. High – end models may have PTFE or CP surface finishing for wear resistance.
2. Key Dimensions: Common diameters range from 4 inches (100mm) to 12 inches (300mm). Tooth counts vary by use—20 teeth for fast cutting, 40 teeth for precision cutting, and industrial large – size blades can have up to 120 teeth. The blade body thickness is 1.2 – 4.0mm, and arbor holes are standard sizes like 20mm, 25.4mm, and 30mm to fit different machines. Jigsaw – type double – direction blades are 50 – 75mm long and 1.3 – 1.5mm thick.
3. Structural & Functional Traits: It has a bidirectional tooth configuration, such as ATB (Alternate Top Bevel) or double – side grind geometry. Many blades are equipped with laser – cut heat expansion slots and stress rings to prevent warping. Jigsaw variants feature a unified shank compatible with both universal and Bosch – style jigsaws.
4. Applicable Scope: It is suitable for cutting hardwood, softwood, plywood, MDF, and paint – free boards. Some high – strength models can also handle materials like PVC pipes and aluminum alloys. It matches angle grinders, table saws, jigsaws, and panel saws.
