Straight Serrated Industrial Blade
A straight serrated edge is the workhorse of bag-making and packaging lines: the teeth grip slippery films that a plain edge would let slide, and each bite leaves a tear-resistant seal line instead of a frayed edge. We grind these blades in tool steel, stainless steel or D2, matched to your product and washdown routine.
Heat treatment is tuned to HRC 56-65 – hard enough to hold the tooth tips through continuous high-speed running, tough enough not to chip when a splice or fold passes through. Every tooth is CNC ground, so pitch and depth stay consistent along the full cutting length.
Because no two machines are alike, everything is custom: length, width, thickness, tooth pitch and hole positions are produced to your drawing or reproduced from a worn sample.

Key Advantages
01Steel Matched to the Job
Tool steel for value, stainless for washdown areas, D2 for abrasive laminates – we help you pick.
02Tear-Free Bag Cuts
Accurate tooth geometry grips film and shears it cleanly, leaving edges that will not fray on the roll.
03Edge That Lasts a Shift
HRC 56-65 hardness keeps tooth tips sharp through long runs, cutting changeover frequency.
04High-Speed Ready
Balanced, straight blades run true in flow wrappers, bag makers and slitters at full line speed.
05Pitch-Consistent Teeth
CNC grinding holds tooth pitch and depth to tight tolerance along the entire edge.

FAQ
Which steel should I choose for my line?
Stainless suits washdown and food areas; D2 wins on abrasive laminates; tool steel covers most standard films. Send us the material list and we will advise.
Can you copy the tooth pitch of my current blade?
Yes – we measure pitch, depth and angle from your sample and reproduce them exactly.
Do you offer stainless serrated blades?
Yes, stainless steel serrated blades are a standard option for wet or food-contact environments.
What is the lead time for a custom profile?
Standard profiles ship in 3-7 days; a new tooth profile takes 7-15 working days including first-article inspection.
