You've probably had someone come to you asking for a file that clears material fast on a rubber conveyor belt or a wooden edge profile, maybe one that won't clog up after a few passes — that's exactly the kind of job these cup-shaped files were made for, and after a decade of moving them, I can tell you the rough single-tooth pattern on the flat section handles that aggressive better than most alternatives.
It basically wants to dig in and remove stock quickly, which is what the rough teeth do, but what it doesn't do is leave a fine finish so you wouldn't want it for final sanding — it's really for shaping, leveling, or cleaning up flash form molded rubber parts, and the 100mm diameter is a sweet spot that feels balanced in a power tool without getting too heavy.
These come off our stamping line in Hebei, and the steel is consistent batch to batch — we see roughly 0.2mm variation across teeth height, which for this grade of work is actually tighter than what cheaper rotary files give you — and the flat cross-section helps keep chatter down when you're working on a flat surfce, say a wooden door edge or a rubber gasket.
Custom branding is straightforward, and our company can do different colors for teh coating if you need to differentiate lines or maybe match your packaing — the MOQ for custom runs is usually 500 pieces or so, but stock orders can be smaller, and we'll send along a COA and HPLC report if you ask, though honestly most buyers just check the first 30 pieces visually.
2-4 weeks is the typical lead time from order confirmation for standdard black oxide finish, but if you need a specific Pantone on the coating, that can push it closer to 5 weeks give or take — one thing I always mention is that the rough teeth will wear faster on hard woods like oak or maple compared to soft rubber, so factor that into your replacement schedule (usually 3-6 months depending on volume).
Our MOQ typically starts at 500 pieces for standard orders. For OEM/ODM projects with custom specs, we can negotiate lower quantities depending on the complexity.
For custom branding or OEM orders, lead time is usually 15-20 working days after sample approval and deposit. Standard stock orders ship within 5-7 days.
Yes, we can provide a material composition test report and a certificate of conformity upon request. The steel meets industry standards for durability in wood and rubber processing.
Absolutely, we can customize the tooth angle or switch to a finer tooth pattern for rubber finishing. Just let us know your desired surface quality, and we'll adjust the die accordingly.
We apply a light anti-rust oil coating before packaging, then wrap each file in bubble wrap and pack them in sealed cartons. For long-term storage, keep them in a dry environment below 60% humidity.
