Find useful answers about bandsaw blades, tooth pitch, blade speed, cutting fluid, break-in procedures and metal sawing performance.
Browse our frequently asked questions to better understand blade selection, cutting speed, feed rate, coolant usage and proper bandsaw blade handling.
The blade pitch or tooth pitch depends on the type and thickness of material being cut. Different tooth pitches are designed for different applications, and selecting the correct pitch helps improve cutting performance and extend blade life.
In general, larger tooth pitches are recommended for thicker materials, while smaller tooth pitches are better for thinner materials. For example, 3–4 TPI is suitable for thick or harder materials, while 10–14 TPI is better for thinner or softer materials.
Breaking in a new bandsaw blade helps it perform properly and last longer. A new blade has a very sharp edge that can be more vulnerable to damage if used too aggressively at the beginning.
The break-in process usually involves running the blade at reduced speed and lighter cutting pressure so the cutting edge develops gradually and becomes more durable.
Blade speed depends on the material type, material thickness and bandsaw blade tooth pitch. Different cutting conditions require different blade speeds to achieve good cutting performance and longer blade life.
As a general guide, slower blade speeds are suitable for harder or thicker materials, while faster speeds are suitable for softer or thinner materials.
Feed, speed and tooth pitch are directly related. To adjust the cut result, it is best to change only one variable at a time.
Increasing work size decreases tooth penetration. A larger tooth pitch increases tooth penetration, while a smaller tooth pitch decreases tooth penetration. Increasing blade speed decreases tooth penetration, while reducing blade speed increases it.
Cutting fluid helps lubricate the cutting edge and reduce heat generated by cutting friction. Excess heat is one of the common causes of blade failure.
Coolant also helps wash chips away from the gullets, cool the blade edge and saw guides, and support longer blade life where coolant is suitable for the application.
Proper folding and unfolding of a bandsaw blade should be done carefully and according to correct handling procedures. Please refer to the recommended instructional video or contact Winsaw for guidance.
Most bimetal bandsaw blades vary in rake angle from 0 to 10 degrees positive rake angle. A positive rake angle provides faster cutting action and helps the blade penetrate harder materials more effectively.
Finer tooth patterns usually have a zero degree rake angle, while more aggressive teeth are commonly manufactured with a higher positive rake angle.
