Use this page as a working brief before you order. KECHOO catalog pages list verified sizes. Custom lengths, unknown machines, and difficult materials still need a technical review.
Confirm these details first
- Length: measure the running blade or read the machine plate. Do not guess from a similar saw.
- Width and thickness: must fit the guides and wheels. A wider blade tracks straighter on a rigid saw; a narrow blade is for curves.
- TPI: keep at least two to three teeth in the workpiece. Thin wall needs a finer pitch; large solids need a coarser or variable pitch.
- Tooth form: regular, variable, hook, or carbide geometry should match chip load and material.
- Application: food, wood, and metal use different constructions. Do not interchange them.
Break-in
New bi-metal and carbide blades need a controlled first cut. Run at the recommended speed with reduced feed until the tooth edges hone. Full feed on a new blade is a common cause of early tooth strip.
When blade life drops
Check guides, wheel condition, tension, coolant mix, chip brush, and feed/speed before changing specification. Many “bad blade” complaints are machine setup. If the specification is wrong for the material, send photos of the tooth, weld, label, and workpiece for review.
Custom and unknown machines
If you cannot read the length, photograph the blade label, the machine model plate, and a tape measurement around the wheels with the blade removed only if it is safe to do so. The technical team will quote from that evidence.

Bandsaw blade questions, answered
Direct answers to the specification and operating questions buyers ask most often.
What size bandsaw blade do I need?
Use the exact blade length, width, and thickness specified on the machine plate or in the saw manufacturer’s manual. The saw type alone is not enough to identify a compatible blade. If the specification is missing, send KECHOO the machine model, an old blade label, or measured blade dimensions before ordering.
How do I choose bandsaw blade TPI?
Choose tooth pitch from the material, its cross-section, and whether the workpiece is solid, tubular, bundled, fresh, frozen, or contains bone. The goal is stable tooth engagement without overloading the gullets. Provide the material and section size when you need a specific recommendation.
When should I choose a hardened, bi-metal, or carbide blade?
Hardened high-carbon steel blades are commonly used for food and bone, woodworking, and general-purpose cutting. M42 bi-metal blades are a versatile choice for fabrication and metal cutting. Carbide-tipped blades suit demanding alloys, abrasive materials, and large sections when the saw and setup are sufficiently rigid.
Can one bandsaw blade be used for meat, wood, and metal?
Do not select a blade by length alone. Meat and bone, wood, and metal applications need different tooth geometry, pitch, blade construction, machine settings, and hygiene or chip-control practices. Match the blade to both the saw and the material being cut.
Why do bandsaw blade teeth strip or wear too quickly?
Common causes include an unsuitable tooth pitch, excessive feed, incorrect speed, poor break-in, low or unstable tension, worn guides, ineffective coolant, a damaged chip brush, or movement in the workpiece. Inspect the failed blade and the complete cutting setup instead of changing only one parameter.
How should I break in a new bi-metal or carbide bandsaw blade?
Start with the saw in good condition and use the blade supplier’s speed, feed, tension, and coolant guidance for the material. Apply a controlled initial cutting load and increase it gradually while checking chip formation and cut stability. A break-in procedure should be matched to the blade, machine, and workpiece rather than treated as one universal setting.
When is a carbide-tipped bandsaw blade appropriate?
Consider carbide for high-alloy steels, abrasive materials, difficult-to-machine stock, or large production sections. The machine should have adequate rigidity, accurate guides, stable tension, effective coolant, and controlled cutting parameters. For an uncertain setup, confirm machine capability before ordering.
What information does KECHOO need to recommend or quote a blade?
Send the application, material grade or product being cut, workpiece size and shape, machine make and model, blade length, width, thickness, tooth pitch if known, estimated quantity, destination country, and the cutting problem or production target. Photos of the machine plate, old blade label, cut, or failed blade can reduce ambiguity.
