Olson 6.5" 18T Coping Saw Blade (30200)

The Olson 30200 delivers 18 teeth per inch of high carbon steel precision — that’s American-made quality. These pin-end blades handle wood, plastics, and non-ferrous metals with equal precision, making them the sensible choice for contractors who need one blade to handle multiple materials on a job site.

The 18 TPI Sweet Spot

At 18 teeth per inch, this blade configuration hits the practical middle ground between speed and finish quality. Compared to Olson’s 15 TPI blade, the 18 TPI provides a smoother finish and cleaner edges. Against their 24 TPI option, the 18 TPI cuts faster through wood while still being general-purpose enough for varied materials.

Each blade measures 6.5 inches between pins — the standard coping saw dimension. The blade width ranges from 0.094 to 0.125 inches, with thickness between 0.018 and 0.020 inches. Those dimensions give you stability in the cut without sacrificing maneuverability around tight curves.

Specification	Value
Blade Length	6.5 inches (between pins)
Teeth Per Inch	18 TPI
Blade Width	0.094 to 0.125 inches
Blade Thickness	0.018 to 0.020 inches
Material	High carbon steel alloy
Tooth Treatment	Individually heat-treated teeth

The real engineering shows in those individually heat-treated teeth. Olson doesn’t just stamp these out and ship them. Each tooth gets its own heat treatment, which means consistent hardness across the blade length. That translates to longer life between replacements and fewer mid-cut failures.

Material Range That Matters

These blades cut through wood, plastics, acrylics, copper, aluminum, brass, and even mild steel. That versatility matters when you’re on a job site. Need to notch copper pipe for a retrofit? Done. Trimming acrylic sheet for a display case? No problem. Cutting decorative brass hardware to length? Same blade handles it.

The 18 TPI configuration works particularly well in Montana’s mixed construction environment. Whether you’re cutting softwood framing lumber or hardwood trim, the tooth spacing handles both without bogging down or tearing out. This TPI configuration aligns with recommendations for delicate, precise cuts, especially in wood, plastic, and nonferrous metals.

Installation follows standard coping saw procedure: loosen frame tension, hook the pins into the frame notches, align teeth direction, then retighten to apply tension. Takes maybe 20 seconds if you’re slow about it.

Universal Compatibility

The pin-end design fits all standard 6.5-inch coping saw frames, including Olson, Stanley, Eclipse, and Robert Larson models. No proprietary nonsense. No brand lock-in. Your existing frames work fine.

The retail 4-pack (CP30200BL) and 12-pack (CP302DZ) configurations suit professional consumption patterns. The retail packaging (UPC 012373302004) shows up in Western Building Center’s Tools department under Misc Blades.

Olson covers these with their standard manufacturer guarantee — typically 30 days through retailers for satisfaction and freedom from manufacturing defects.

The Bottom Line

Skip these if you only need rough cuts in dimensional lumber — grab the 15 TPI version instead. But for finish work, trim carpentry, or any job mixing materials, the 18 TPI configuration earns its place in the toolbox. These are Made in USA blades that deliver professional results.

The single review available — “Right size and it’s a good product for me” — doesn’t tell much. But with these specs, they’re worth trying for yourself.

Frequently Asked Questions

What materials can these Olson 18 TPI coping saw blades cut?

The blade handles wood, plastics, acrylics, non-ferrous metals like copper, aluminum and brass, plus mild steel. The 18 TPI configuration works best on materials where you need a balance of cutting speed and smooth finish.

How are these blades installed in a coping saw?

Loosen tension on your saw frame, hook the blade pins into the frame notches, make sure teeth face the right direction for your cutting style, then retighten the frame to apply proper blade tension.

What coping saw frames work with these blades?

Any standard 6.5-inch coping saw frame works, including models from Olson, Stanley, Eclipse, and Robert Larson. The blade uses standard pin-end design that’s been the industry standard for decades.

How does 18 TPI compare to other tooth counts?

The 18 TPI provides smoother finishes than Olson’s faster-cutting 15 TPI blade, but cuts more aggressively than their 24 TPI ultra-fine option. Think of 18 TPI as your general-purpose choice when you need good finish quality without sacrificing cutting speed.
