A negative hook angle on a saw blade means the blade’s teeth tilt slightly backward. This angle helps control the cutting action, especially on easily chip or splinter materials like laminates, plywood, or metals. Use a blade with a negative hook angle for cleaner cuts in these materials and more controlled cutting on radial arm saws.

Saw blades specifically designed for aluminum are versatile and can handle other non-ferrous metals like brass, copper, and certain plastics. These blades have a unique tooth geometry and material composition that prevents binding or excessive heat buildup, making them suitable for soft metals but not for ferrous metals (like steel), which require a different blade type.

Cooling is essential when cutting aluminum to prevent the blade from overheating and to achieve a smooth cut. Use a Mist Coolant System when cutting non-ferrous metals. The Mist Coolant reduces friction and keeps the blade and material cool, extending the blade’s lifespan and improving cut quality.

Yes, tooth count is crucial for aluminum cutting. Blades with more teeth provide a smoother finish and are ideal for thin-walled aluminum or precise cuts. For thicker aluminum pieces, fewer teeth can prevent the blade from clogging, which improves efficiency and longevity.

Cutting aluminum requires extra care due to its tendency to produce sharp chips. Always wear eye protection, consider a blade with a negative hook angle to minimize pull, and secure your material to avoid shifting during cuts. When securing material, consider adding a Pneumatic Clamping System to your Radial Arm Saw.
