Cost Comparison of Blade Types
Approximate Cost of Regrind (Re-sharpen) Carbide-Tipped Saw Blades
24” Diameter, 60 teeth saw blade:
|The cost of a new blade at 24” (610 mm) x 60 teeth||$ 390.00|
|4 times retipping 60 teeth = 240 tips at $3.50/tip||$ 840.00|
40 x 5 teeth replacement = 200 tips at $5.35/tip
|40 times regrinding at $54||$ 2,160.00|
| Re-tensioning and other general maintenance at each regrind process
40 x $10/blade (approximate cost $10 per regrind)
| Total Cost for a blade
(Assuming free shipment by the blade repair shop)
|Average tool life 15,000 sq. in. (9.7 m2)/blade for one usage.
Total tool life for the life of a blade = 15,000 x 40= 600,000 sq. in. (384.6 m2)
Average Cost per square inch of cut for 24” – 60 teeth resharpenable saw blade ($4,860/600,000) =
Approximate Cost of One Way blades
|Approx. Cost of a 24” - 80 Tip 0.12’’ (3 mm) kerf (tooth width) blade||$ 461.00|
| Tool life is much higher due to the coating, and is about 50,000 sq. in. (32 m2)
The cost per square inch is ($461/50,000) =
| $.009/sq. in.
Approximate Cost of Replaceable Carbide-Tipped Circular Saw Blades
- What machines are available (HP, RPM, Stiffness, etc.)?
- How experienced is the saw operator?
- What material will be cut (chemical composition, hardness, shape, etc.)?
- What are the stock sizes and length?
- Quantity of cuts, per day, per week; and number of shifts?
- Is the shop location close to a good blade repair shop?
- What are the shop environments (quality of operation, maintenance, etc.)?
- What is the highest cutting rate?
- Is the machine fully automatic?
- Unattended operation required?
- Operator controlled production?
- Is Material loss due to wider Kerf critical?
- Is a new saw needed?
