Blade for mitre saw DT99569 216 mm Use the new XR FLEXVOLT mitre saw blades alongside the DCS777 for the optimal cordless performance. The extra sharp carbide teeth give longer useable life between re-sharpening.

The optimised tooth form combining two alternate top bevel teeth followed by a raker tooth allows for the efficient cutting and cleaning of the kerf. This minimises the battery power required to make the cut line and prolong's battery life.


Thinner carbide teeth allow the blade to pass through timber with less resistance. Less power is required to drive the teeth through the wood resulting in more cuts per charge.
