شفرة إنفينيتي تولز البديلة لقطع فتحات الأبواب الخارجية مقاس 1/2 بوصة لمجموعة صنع الأبواب الداخلية/الخارجية Insert-Pro

Was swapping out the old blade from my exterior door kit and this C4 carbide knife sliced through the PVC jamb like butter. Fit perfectly with no wobble, and the edge is holding up way better than the original included one.

Installed it this morning and the C4 carbide held its edge through the entire door without any chipping. The fit was spot-on for the Insert-Pro kit, no wobble at all. Really glad I grabbed this as a spare.

The C4 carbide on this knife is noticeably sharper than the stock blade that came with my kit—cut through the exterior door slot like butter on the first pass. Exactly what I needed for a clean fit on a new door install.
