Circular Saw Blades

Circular Saw Blade Selection — Quick Reference

Circular saw blade selection drives cut quality + tool life + operator safety. Match by material being cut (timber/steel/SS/specialty) + tooth count + blade material (HSS vs TCT vs cermet vs diamond).

Critical: Match blade MAX RPM to tool spec — exceeding RPM = catastrophic blade failure. Tooth count rule: more teeth = cleaner cut but slower; fewer teeth = faster but rougher. NEVER use timber blade on metal — heat + tooth design = blade failure. Match arbor (centre hole) diameter to saw spec. Brands: Austsaw, Bordo, Sutton Tools, Excision. Companion: Austsaw range, diamond saw blades, cut-off discs.

Circular Saw Blades for Wood, Stainless Steel, Specialty Materials and Rotary Hacksaw Cutting from AUSTSAW, Bordo, Sutton Tools and Excision

AIMS Industrial sells an extensive range of circular saw blades from Bordo, Sutton Tools and Austsaw & Excision, covering TCT (tungsten carbide tipped) blades for timber, hardwood, nail-embedded wood and sleepers, thin-kerf general purpose blades, stainless steel cutting blades, rotary hacksaw blades and specialty panel-cutting blades. Whether cutting standard framing timber, rough recycled hardwood, stainless steel sheet or composite panel materials, we have the blade specification for the job.

Some Blade Types in Our Range

• AUSTSAW Extreme Wood with Nail Blade: TCT circular saw blades designed to cut through nail-embedded, recycled or rough-sawn timber without damaging the blade. Used in demolition, construction and recycling applications where embedded nails, screws or fixings are present in the material.
• AUSTSAW Extreme Stainless Steel Blade: Circular saw blades formulated for cutting stainless steel sheet and tube. Correct blade selection for stainless steel is critical — standard steel blades will overheat, work-harden the cut edge and fail prematurely.
• AUSTSAW Redgum Sleeper Blade: 235mm (9-1/4") blade with 25mm bore and 6-tooth configuration for cutting extremely hard and dense timbers including railway sleepers, ironbark and redgum. The low tooth count and heavy-duty TCT tips are designed to handle the abrasive, silica-rich nature of hardwood sleepers.
• AUSTSAW Rotary Hacksaw Blade: Specialty circular saw blade designed for cutting thin-walled steel tube, angle iron, flat bar and metal sections in a circular saw. Offers an alternative to an angle grinder cut-off wheel for straighter, more controlled metal cuts.
• AUSTSAW Panel Cutter: 150mm specialty blade with four cutting edges for cutting composite panels, laminates and thin sheet materials. The panel cutter design minimises tear-out on finished surfaces.
• Bordo Rapidcut Thin Kerf Blade: Thin-kerf TCT circular saw blade for fast, clean cuts in standard framing and construction timber. The reduced kerf width means less material removed per cut, faster cutting speed and less load on the saw motor.

People Also Ask — Circular Saw Blades

Q: What circular saw blades does AIMS stock?

Tungsten carbide tipped (TCT) blades: workshop standard for wood, metal, and composite cutting — long life, can be sharpened. Steel blades: cheaper, suitable for occasional cutting in softer materials. Diamond blades: for masonry, concrete, tile, stone cutting. Specialty blades for laminate, plastic, and non-ferrous metals. Common diameters: 165mm, 184mm, 235mm, 254mm, 305mm. Match blade to material, tool size, and cut quality required. See [Bandsaw Blade Guide](/blogs/product-guides/blog-band-saw-blade-guide) for related saw blade information.

Q: How many teeth on my circular saw blade?

Fewer teeth (24-40): fast cutting, rough finish — suits framing timber, demolition. More teeth (60-80): smooth cutting, fine finish — suits finish work, plywood, laminate. Specific tooth counts: 24T (framing rip cuts), 40T (general workshop wood crosscut), 60T (laminate, melamine, fine finish), 80T (premium finish, MDF, plastic). Higher tooth count cuts slower but cleaner. Match tooth count to required finish and material thickness.

Q: What blade for cutting metal?

Standard TCT wood blades aren't suitable for metal — wrong tooth geometry overheats and damages teeth. Metal-cutting TCT blades: triple-chip grind tooth geometry, optimised for steel and aluminium cutting. Cold-cut metal blades: very high tooth count, designed for dry metal cutting without coolant. For thin sheet aluminium and steel: dedicated metal-cutting circular saw blades. For thick steel: abrasive cutting wheels or bandsaw. Don't use wood blades on metal — damages blade and creates safety hazard.

Q: Can I sharpen circular saw blades?

Yes — TCT (tungsten carbide tipped) blades sharpen with specialty grinding equipment. Cost varies by tooth count: small workshop blades $30-60 for resharpening, larger blades $80-150. Quality TCT blades sharpen 3-5+ times before replacement. For volume users, blade resharpening pays back over replacement. AIMS can refer to qualified blade-sharpening services. For cheap one-time blades, replacement is more economic. For premium blades, resharpening extends service life significantly.

Q: Safety equipment for circular saw use?

Eye protection (safety glasses minimum, full face shield for prolonged use), hearing protection (circular saws are loud), dust mask (wood and material dust), cut-resistant gloves (though gloves controversial for power tool use — many trades work bare-handed for grip), and FR clothing for sustained metal cutting (sparks). Verify blade is suitable for material being cut. Check blade for cracks or missing teeth before use. Never override blade guards — they protect the operator.
