FAQs:

Q: How do I get the most out of my saw blades? 

A: Saw blades are engineered for cutting a specific material. Do not force feed, but let the blade do the cutting.  If the blade is not cutting at speed, check to see that it is clean and sharp.

Have Raleigh Saw sharpen your blades for you before they become dull.  Continuing to use a dull blade will decrease the performance and the service life of the saw blade.  To sharpen and extremely dull blade, the teeth must be ground much more than normal, resulting in fewer sharpenings and a shorter blade life (OSHA safety regulations require all cracked saws be taken out of service).

 

Q: Why should I sharpen my blades?

A: There are many reasons that you should sharpen your blades. It extends blade life, improves your cut quality, saves on your production cost, reduces waste (an unclean cut can damage material), and sharpening your blades also improves your safety.

 

Q: What are the indicators that show I need to sharpen my blades?

A: Cut quality deteriorates, feed pressures increase, wood products will tend to burn or cause pitch build up on blade, plastics will chip and or melt, and aluminum will get hot as the blade dulls and cause aluminum to adhere to the carbide.

 

Q: Approximately how many times can a blade be sharpened?

A: This depends on the size of the original carbide tip used on the new saw as well as the dullness of the blade when it is resharpened. 

 

Q: What is the approximate turnaround time for blade sharpening?

A: Approximately one week from the time that the item is received.

 

Q: What is the correct RPMs for saw blades?

A: According to OSHA standards; maximum safe cutting speed is 18,000 surface feet per minute (SFM) when cutting wood*.  This is the maximum safe saw speed, but does not necessarily reflect the best saw speed.  The most efficient results are usually obtained at somewhere between 1/2 to 3/4 of the maximum speed.  This will vary depending on the type of saw and material being cut.  The table below is intended only as a guideline.
