Products Description
3/16" (4.8mm) Gold-Titanium Chainsaw Round File
Industrial .325" Pitch Sharpening Tool
Premium 8-Inch Abrasive Sharpening Rod featuring PVD Titanium-Nitride Coating for High-Velocity .325 Chain Restoration.
Round file 3/16＂4.8mmx8"gold
The 4.8mm chainsaw file is a high-precision abrasive tool purpose-built for accurate geometry restoration on mid-range chainsaw cutters. Manufactured from hardened T12 tool steel and enhanced with premium PVD titanium nitride coating, it enables fast, clean material removal while delivering exceptional thermal stability during continuous sharpening work.
Precision-calibrated to eliminate edge glazing and overheating, this professional file preserves the structural integrity of the cutter's chrome surface. It maintains consistent cutting sharpness through frequent maintenance cycles, ideal for high-intensity timber harvesting and large-scale municipal groundskeeping operations.
Technical Profiles & Materials
Precision Abrasive Geometry: Features an optimized single-cut helical profile, designed to facilitate high-volume chip evacuation and maintain consistent tooth engagement without mechanical drag.
Hardened Metallurgical Substrate: The core is forged from high-density hardened T12 alloy, providing superior flexural rigidity and absolute immunity to vibrational fatigue under peak manual operational torque.
Micro-Calibrated 4.8mm Span: Manufactured via high-tolerance centerless grinding, ensuring a ±0.03mm diameter precision for a perfect seat in the cutter gullet, optimizing the working angle for high-torque wood severance.

FAQ
Q: Are you an impartial industrial components dealer or a direct China water pump factors factory?
A:We are a direct, ISO9001-certified engineering water pump components manufacturing facility and precision fluid-control factor manufacture exporter primarily based in China. We function our personal cleanroom injection molding bays, computerized ultrasonic welding arrays, computerized hydraulic stress check stations, and clean-room packaging lines, passing direct-factory wholesale price financial savings straight to your element procurement margins.
Q: Can your manufacturing unit furnish full certification forms for food-contact or consuming water compliance?
A: Yes, absolutely. For food, beverage, or scientific applications, our manufacturing unit makes use of one hundred percent virgin, un-recycled polypropylene resins accompanied by means of fabric traceability certificates. We mechanically furnish B2B purchasers with complete FDA compliance documentation, NSF-grade compound declarations, and RoHS/REACH chemical protection screening sheets to make certain clean clearance thru worldwide customs.
Q: Do you provide customization picks for distinctly corrosive fluids like sturdy acids or ozone?
A: Yes, we are a thoroughly succesful OEM/ODM supplier. For aggressive chemical or ozone environments, we can improve the 12x26.5mm valve configuration in our factory: substituting the general PP housing with top class PVDF (Fluoropolymer) and changing any steel springs with Hastelloy or whole springless gravity-ball architecture, making sure final chemical resistance.
Q: How do we impervious a pattern batch to execute computerized lifecycle and burst-pressure testing?
A: We relatively inspire complete laboratory contrast earlier than logging mass grant agreements. We can ship a pattern lot of 5-10 gadgets of our inventory 12x26.5mm take a look at valves for assessment (setup costs and DHL/FedEx air freight apply). Once the factors pass by your inner lifecycle verification and a formal wholesale quantity manufacturing contract or container run is locked in, the sampling charges are a hundred percent credited returned to your industrial balance.
