Focus on 4 core parameters:
- Material: Wood, Metal, Frozen Meat, etc.
- Size: Length × Width × Thickness (match your saw)
- TPI: Teeth Per Inch (higher TPI for thin material)
- Blade Type: Carbon Steel, M42 Bi-Metal, Food-Grade Stainless Steel
For detailed guidance, refer to our Product Catalog or free consultation.
We recommend SK5 Carbon Steel with Variable Pitch (变齿距) or M42 Bi-Metal for hardwood.
- SK5: Cost-effective, good toughness for general hardwood
- M42: Higher wear resistance, longer service life for high-volume production
Absolutely not. Wood blades are designed for low hardness and flexibility, while metal requires high hardness and toughness.
Using a wood blade on metal will cause rapid tooth breakage and severe blade damage. Always choose an M42 Bi-Metal blade for metal cutting.
Wrong tension is the top cause of blade breakage. Follow this rule:
- 1/2″ width blade: 25,000 – 30,000 psi
- 3/4″ width blade: 35,000 – 40,000 psi
Always confirm the specific value in your saw’s user manual. Too little tension causes wandering; too much causes snap.
- Unplug the machine first
- Place the blade on the wheels, ensure teeth point downward
- Adjust guide blocks to touch the blade lightly (1-2mm gap)
- Test run by hand to ensure smooth tracking
- Clean after use: Remove debris with a brush
- Oil for rust prevention: Apply light oil for carbon steel
- Release tension: Long-term storage without tension
- Check guides: Replace worn blocks regularly
Proper maintenance can double your blade’s service life.
Yes, it is critical. New blades have extremely sharp teeth.
Break-in steps:
- Set speed to 70% of normal
- Make 3-5 test cuts on scrap material
- Gradually increase speed and feed rate
Common causes:
- Wrong TPI: Too coarse for thin material
- Over-tension: Too much pressure causes snap
- Bad Installation: Blade twisted on wheels
- Material Impurities: Knots in wood or metal inclusions
Solutions:
- Check TPI: Too low TPI for thick material causes vibration
- Adjust Guides: Too far from workpiece increases vibration
- Reduce Feed Rate: Too fast causes burning and rough finish
- Blade Sharpness: Dull blades cause rubbing instead of cutting
