Most guys come in asking about sizes first, but what really matters is the metal—we've been handling these C files for years and the premium stainlss steel is what keeps them from snapping in tight curves, and we actually run tensile tests on every production batch to confirm consistency, so you're not guessing.
They're really meant for those tough cases where the canal is curved or calcified, and the 25mm length is pretty standdard for most adult molars, though some premolars might need a shorter one—we don't carry that, but your usual suplier might.

6 pieces per box in sizes #6, #8, and #10, and the #8 is what most buyers order first, probably because of that it splits the difference for general prep work—I usually keep extra in stock, but confirm lead time; our MOQ is 50 boxes and the retest policy is straightforward.

The ISO and FDA certs are issued annually, and we audit the testing lab ourselves—if you get a batch and something feels off, we'll cover the HPLC retest at our cost, basically no questions asked, but that almost never happens with these.

What it does is hold up under torque better than some of cheaper imports out there, and the uniform structure is a detail most reps skip, but you notice it when you're working a #6 through a tight curve—it's a solid spec that matters more than the 0.04 taper.
Actually, don't expect this to work well in straight, wide canals—that's not what it's for, and you'll get better results with a Hedstrom or K-file in those cases, so pick your tool accordingly.
The DCF-25 comes in sizes #6, #8, and #10, all 25mm long. They're specifically designed to handle curved and calcified canals, so yes, they work great for tricky root canals.
We typically require a MOQ of 100 boxes per size, but we can negotiate for trial orders. Just let us know your quantity needs.
For confirmed orders, lead time is usually 15-20 working days. Larger quantities might take a bit longer, but we'll confirm the exact timeline after you place the order.
Yes, we provide ISO and FDA certificates with every shipment. Just request them when you place the order, and we'll include the docs in the package.
Each box contains 6 pieces, and they're individually sealed to keep them sterile. We pack multiple boxes in sturdy cartons to prevent damage during transit.
