MPN: 22211

Barcode: 5028734222111

Size: 300mm (12")

Weight: 0.97kg

Overview:

The Blue Spot Tools 5 Piece 24TPI Hacksaw Blades are manufactured from heat treated carbon steel for increased hardness and cutting performance. With 24 teeth per inch, they handle metal, plastic, and certain types of wood without switching blades.

At 300mm (12") in length, each blade fits most standard hacksaw frames of the same size. The pack of five gives you spares ready for longer cutting tasks or when a blade wears down.

Key Features and Benefits

• Increased hardness: Heat treated carbon steel construction delivers better cutting performance across a range of materials.
• Cleaner cuts: 24 TPI produces smoother results through metal and plastic compared to lower TPI options.
• Wide compatibility: Standard 300mm (12") sizing fits most hacksaw frames without any modification.
• Pack of five: Spares are always on hand during longer cutting tasks or when a blade wears down.
• Edge retention: Heat treatment helps the blade stay sharper for longer between replacements.
• Multi-material use: Cuts through metal, plastic, and certain types of wood without needing to swap blades.
• Controlled cutting: Consistent tooth spacing supports steadier strokes and more accurate cuts.

Typical Applications

• Cutting steel pipes, tubing, and bar stock
• Cutting plastic conduit and piping
• Cutting aluminium sections and profiles
• Trimming wooden dowels and thin timber lengths
• Cutting bolts, screws, and threaded rod to length
• Plumbing and pipework maintenance tasks
• Electrical installation work involving conduit
• General workshop cutting and fabrication

How to Use

• Blade fitting: Insert the blade into the hacksaw frame with the teeth pointing away from the handle, then secure firmly.

• Tensioning: Tighten the frame tensioning nut until the blade has no sideways flex.

• Workpiece: Clamp the material securely in a vice or with clamps before starting the cut.

• Starting the cut: Begin with short, light strokes to create a small groove and guide the blade on line.

• Cutting: Apply pressure on the forward stroke only. Use long, steady strokes along the full blade length.

• Blade inspection: Check the blade regularly. Replace it when teeth appear flat, worn, or the cut line starts to drift.

Frequently Asked Questions (FAQs)

• What is the difference between carbon steel and bi-metal hacksaw blades?
  Carbon steel blades cut softer materials including general metals, plastic, and wood. Bi-metal blades combine a high-speed steel cutting edge with a flexible carbon steel back, making them better suited to cutting harder metals over extended use.

• How many TPI do I need for cutting metal pipe?
  For most metal pipes and tubing, 24 TPI gives a good balance between cutting speed and finish quality. Thinner-walled tubing benefits from 24 to 32 TPI, while thicker sections can be cut with 18 TPI.

• Why does my hacksaw blade keep breaking?
  Blades typically break due to incorrect tensioning, twisting the frame mid-cut, or applying pressure on the return stroke. Always tension the blade firmly and apply downward pressure on the forward stroke only.

• Can I use a hacksaw blade without a frame?
  Hacksaw blades are designed to work under the tension provided by a hacksaw frame. Removing that tension makes the blade flex during cutting, which reduces accuracy and significantly increases the risk of snapping.

• How do I know when a hacksaw blade needs replacing?
  Replace the blade when cuts take noticeably longer than before, the cut line starts to wander, or the teeth look visibly flat or chipped. A worn blade also requires more physical effort to drive through the material.

Summary

These Blue Spot Tools heat treated carbon steel hacksaw blades come in a pack of five and measure 300mm (12") in length. With 24 teeth per inch, they cut metal, plastic, and certain types of wood, and fit most standard 300mm hacksaw frames. The heat treatment process increases blade hardness, supporting consistent cutting performance across general workshop and maintenance tasks.
