Why choose it

The Bosch 42403 combines a rigid, anti-vibration blade body with precision-ground carbide teeth to maintain accuracy and reduce noise during operation. Its expansion slots dissipate heat, preventing warping and extending blade life. The 15° hook angle ensures fast, aggressive cutting in rip applications while still producing a smooth finish in crosscuts.

• Cross-cutting plywood and MDF panels without chipping
• Processing chipboard in furniture manufacturing
• General construction and carpentry cutting tasks

Good to know

Always verify that your saw's arbor size matches the 30 mm bore and that the blade's maximum speed rating exceeds your machine's RPM. For best results, use a stabilizer or dampener if your saw supports one, and keep the blade clean from resin buildup to maintain cutting performance.
