Hand saw Irwin 990 550 mm (22") 9 TPI

The Irwin 990 hand saw with a 550 mm (22") blade and 9 TPI tooth pitch is a manually operated wood-cutting tool intended for general carpentry and rough cutting tasks. The full-size blade supports long, straight strokes for efficient removal of material, while the 9 TPI tooth configuration provides a compromise between cutting speed and a reasonably smooth finish. The handle is shaped to allow two-handed control and to reduce fatigue during sustained use.

Advantages

The saw combines a long blade for efficient rip and cross cuts with a tooth pitch selected to suit both speed and surface quality. Its full-size blade design helps maintain straight cutting lines across boards and timber. The handle is ergonomically formed to provide secure grip and improved control during forceful or extended sawing actions. The simple, manual design makes the tool reliable and easy to maintain without power requirements.

Suitable for

• General carpentry and framing work
• Rough cutting of lumber and dimensional timber
• Cutting stud work and on-site timber trimming
• DIY woodworking projects requiring long, straight cuts

Key specifications

• Blade length: 550 mm (22")
• Tooth pitch: 9 TPI (teeth per inch)
• Blade type: full-size hand saw blade for manual long-stroke cutting
• Primary material application: wood and timber
• Handle: two-handed ergonomic handle for improved control

How to use

Secure the workpiece before cutting to prevent movement. Position the saw with a comfortable stance, placing one hand on the top of the handle and the other for guidance or additional control. Start the cut with a few light forward strokes to establish a straight kerf, then use long, steady strokes relying on the full blade length to maintain a straight line. Allow the saw’s teeth to do the cutting; avoid excessive downward pressure which can cause binding or uneven cuts. Finish the cut with controlled, shorter strokes as you near completion to reduce splintering.

Usage recommendations

Use the Irwin 990 hand saw for on-site framing and general timber trimming where a balance of cutting speed and surface finish is required. Keep the blade clean and free of pitch; periodically check the handle for secure attachment. When smoother finishes are needed after cutting, follow up with a finer-tooth saw or sanding. For safety, wear eye protection and gloves and ensure stable clamping of the workpiece.
