This laser cut Titanium Carbide-Tipped (TCT) circular saw blade has a PTFE coating, which improves the ease of the cut, reduces heat in the blade and prevents rusting and resin build-up. The micrograin titanium carbide teeth provide thin cuts and little waste. The heat expansion slots are laser cut and this provides the blade with enough room to expand when it heats up. Anti-friction vents tap vibrations ensuring the blade runs more true without any unbalance. These vents also limit the amount of noise from the blade, which is great for use in a quieter working environment. The anti-kickback design prevents the blade feeding too quickly. Designed for use on hardwood, softwood, MDF, chipboard and plywood. Compatible with most 165mm circular saws with a 20mm and 16mm bore including Stock No. 55519, 89451 and 57341. EN847-1 Standard.
