GRAFF 8% Cobalt Premium Hacksaw Blades 12 Inch for Stainless Steel and Metal Cutting 24 tpi - Handsaw Blades Replacement Bi-Metal

The GRAFF 12-inch bi-metal hacksaw blade is built for manual metal cutting tasks requiring both strength and precision. Made for cutting through various metals and steel types, including stainless steel, this replacement blade provides metalworkers and DIY users with a durable edge for hand sawing work. It features a 24 tpi configuration designed for clean cuts across thin to medium metal stock.

The blade incorporates an 8 percent cobalt composition within its bi-metal build. This cobalt content helps the teeth withstand heavy friction and abrasion when working against tough metal surfaces. With a small tooth pitch at 24 teeth per inch, the blade removes material cleanly while helping maintain controlled cutting paths. In addition, the bi-metal body offers noticeable flexibility, allowing the 300 mm blade to bend under pressure during manual sawing without snapping or losing its cutting efficiency.

Measuring 300 mm in length and 0.62 mm in thickness, this blade is proportioned to fit standard manual hacksaws and various hand saw frames. The narrow 0.62 mm profile aids in keeping kerf waste minimal during straight cuts, while the standard 12-inch length provides full stroke distance across standard hacksaw frames.

While the 24 tpi tooth structure handles sheet metal, pipes, and stainless steel effectively, it may cut slower on soft or very thick materials where larger tooth spacing would clear debris faster. Additionally, the manufacturer information does not state whether the package includes a single replacement blade or a multi-pack, so buyers should check the listing details to know the exact blade count included.

Verdict: This GRAFF replacement blade is a practical choice for anyone needing a flexible, abrasion-resistant hacksaw blade for cutting stainless steel and general metals. Its 8 percent cobalt bi-metal build makes it well suited for routine workshop maintenance and manual metalworking tasks.

• Brand: GRAFF
• Blade Length: 300 mm (12 inches)
• Blade Width: 0.62 mm
• Tooth Count: 24 TPI (teeth per inch)
• Material: Bi-metal with 8% cobalt content
• Compatibility: Standard hacksaws and hand saws
• Intended Uses: Metal, steel, and stainless steel cutting

A great fit if you:

• Need to perform manual metal cutting on tough materials like stainless steel using standard hand saws.
• Want a flexible bi-metal blade that can bend under working tension without breaking or losing efficiency.
• Require a fine 24 TPI tooth pattern for precise, abrasion-resistant cuts through steel stock.
• Are looking for replacement 12-inch blades compatible with general manual hacksaw frames.

Consider something else if you:

• Primarily cut non-metallic items like wood or plastic where a coarser tooth pitch is preferred.
• Require power tool saw blades designed for reciprocating saws rather than manual hacksaws.

Confirm on the listing:

• Check how many replacement blades are included in the package purchase.
• Verify that your hacksaw frame accepts standard 300 mm (12 inch) replacement blades.
• Confirm whether your cutting job requires a 24 TPI tooth pitch or a different tooth density for your material thickness.

How to compare your options: When selecting hacksaw replacement blades, compare tooth count, material composition, and blade dimensions. Higher tooth counts like 24 TPI are targeted at precise cuts on metal and steel, whereas lower tooth counts suit thicker or softer stock. Look for cobalt-infused bi-metal options if your work involves hard alloys like stainless steel, and check that the 300 mm length matches your frame size.

To maximize performance, ensure the blade is mounted in your hacksaw frame with the teeth pointing forward, away from the handle, so it cuts on the forward stroke.

Maintain proper tension on the blade within the frame prior to cutting to prevent excessive twisting or blade wander.

When working on hard metals like stainless steel, apply steady, even pressure and consistent stroke speed to let the 8 percent cobalt teeth cut effectively without binding.

Store spare blades in a clean, dry area after use to protect the teeth and mounting ends from unnecessary wear or storage damage.
