DeWALT XR Extreme Runtime Circular Saw Blade 305mm 78T 30mm Bore DT99576-QZ
Description & Specs
The DeWALT XR Extreme Runtime 305mm circular saw blade pairs a 305mm diameter with a 30mm bore for larger saws, and its high 78-tooth count is built for fine, clean cutting. That makes it well suited to second fix work and finishing cuts in hardwood, plywood, MDF and chipboard where edge quality matters.
- Diameter: 305mm
- Teeth: 78T
- Bore size: 30mm
- Range: XR Extreme Runtime
- Model: DT99576-QZ
Check the 305mm diameter and 30mm bore suit your saw before fitting. A 78-tooth blade favours a smooth, splinter-reduced finish over outright speed, making it a good choice for trim, joinery and sheet material cutting.

Satisfied customer
Had been looking at the DeWALT XR for a couple of months. DEWALT build quality is obvious as soon as you open the box — feels solid and well finished. Easy to set up and works exactly as described. Delivery to Perth in only 3 days which is impressive. Will be buying more from SuperSaver AU for sure.
Exceptional — 5 stars

Absolutely love it!
Had the DeWALT XR on my wishlist for a few weeks and finally pulled the trigger. Arrived in 2 days which was a nice surprise. Build quality is solid and exactly what the photos showed. My partner uses it every day now and has already asked me to grab another one as a gift.
Best buy of the year
Ordered Thursday and had it by Saturday. Packaging was really good — nothing moved around. Works exactly as expected and the price was well below what I saw in stores.
