Band Saw Cutting Time
How long does each cut take on the band saw, and how many cuts per hour?
Cross-section area, cutting time per cut from the blade maker’s cutting rate, and output per hour including handling time, for round, rectangular and tube sections.

How this tool works
Inputs, units and where to find them
| Input | Unit | Typical source |
|---|---|---|
| Section | choice | Shape of the stock. |
| Diameter or width | mm | Bar diameter, or width of a rectangular section, or tube outside diameter. |
| Height (rectangular) or wall (tube) | mm | Height of a rectangular section, or tube wall thickness (ignored for round bar). |
| Cutting rate | cm²/min | Area cut per minute for the material and blade, from the blade maker’s chart or your records. |
| Handling and approach time per cut | s | Time to index, clamp and approach for each cut. |
Method and formulas
- Area: round πD²/4; rectangle w × h; tube π(D² − (D − 2t)²)/4.
- Cutting time = area ÷ rate.
- Cuts per hour = 3600 ÷ (cutting time + handling time in seconds).
- Example: a 100 mm round bar at 40 cm²/min takes 1.9635 min to cut.
Limitations
- Cutting rates vary with material, blade, feed pressure and coolant; rates from tests are best.
- Bundle cutting and blade breakdown time are not included.
- Example values are illustrations. Replace them with values for your actual task.
Typical uses
- Estimate saw time for a cutting list
- Quote sawing and preparation
- Compare blade and material options
Who it is for
- Saw operators
- Estimators
- Production planners
What you get
- Cut area
- Cutting time per cut
- Cuts per hour
Interpreting the result
- Tubes and structural shapes cut faster per area but need finer-tooth blades.
