Product Specification
4-1/2" 18-TOOTH TCT SAW BLADE FOR FAST CUTTING & TRIMMING
The Benchmark Abrasives 4-1/2" 18 tooth TCT saw blade is built for fast, efficient cutting and trimming of hardwoods, softwoods and plywood. Its lower 18-tooth count favors cutting speed and chip clearance, making it a practical choice for framing, trimming and everyday jobs where productivity matters more than achieving the finest possible finished edge.
Precision-ground tungsten carbide-tipped teeth and ATB (Alternate Top Bevel) geometry provide durable, dependable cutting performance across common wood materials. The thin 0.071" kerf helps reduce cutting resistance and material removal, making this compact blade especially well suited for portable circular-saw applications.

Materials & Applications
Best For
- Softwood
- Hardwood
- Plywood
- Construction lumber
- Wood framing
- Decking
- Fast general cutting
- Trimming
The 18-tooth configuration makes this blade particularly useful for framing, construction, repair and trimming applications where a fast, efficient cut takes priority over a fine-finish edge.
Machine Compatibility
Designed for compatible 4-1/2" compact circular saws with the proper arbor configuration and operating speed.
Common compatible saws include:
- Porter-Cable® PCE381 4-1/2" Compact Circular Saw
Always confirm compatibility with your exact saw before installation. Blade diameter, arbor or bushing fit, guard and flange clearance, blade rotation, kerf and any applicable riving-knife requirements must match, and the saw must operate at no more than 14,000 RPM.
Choosing the Right Tooth Count

With 18 teeth on a 4-1/2" blade, this blade sits on the faster, more aggressive side of the wood-cutting range, making it well suited for fast cutting, framing and trimming.
Tips for Better Blade Performance
- Secure the workpiece firmly before cutting.
- Use a steady feed rate and allow the carbide teeth to do the cutting.
- Avoid forcing the blade through the material.
- Keep sawdust and debris clear of the cutting path.
- Inspect the blade before use for damaged, missing, or excessively worn teeth.
- Remove pitch and resin buildup periodically to maintain cutting performance.
- Replace or professionally sharpen the blade when cutting performance noticeably declines.
- Never exceed the blade's 14,000 RPM maximum operating speed.
Safety
- Use this blade for wood-cutting applications only.
- Do not use this blade to cut metal.
- Use only on saws designed to accept this blade diameter and arbor configuration.
- Never install the blade on a machine that exceeds the blade's maximum RPM.
- Keep all factory guards installed and properly functioning.
- Inspect the blade before every use. Do not use a cracked, warped, or damaged blade.
- Secure the workpiece and maintain control of the saw throughout the cut.
