Solid Tungsten Carbide Rods 300–330 mm, WC-Co Cemented Carbide Grades
Buyer-facing sourcing candidate for solid cemented tungsten carbide rods made from WC-Co material, offered in common grades such as K10, K20, K30, K40, YL10.2, YG6, YG8, YU06, and YU12. Suitable RFQ focus includes diameter and length tolerance, cobalt percentage, grain size, hardness, TRS, density, surface finish, packing method, export documents, and HS code confirmation. This item is better treated as an industrial carbide tooling raw material rather than a fine chemical.

Package and route
Packing notes
Supplier reports plastic box and standard export carton packing; confirm inner protection against chipping and edge damage
For precision rods, request individual sleeves, foam separation, or rigid trays if surface finish and tolerance preservation are critical
Confirm carton gross weight, net weight, dimensions, palletization, and moisture protection before booking freight
Request photos of standard packing and export marks before shipment
For courier shipment, confirm packaging is suitable for brittle cemented carbide rods and long 300–330 mm lengths
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Raw blanks for drill bits, end mills, reamers, and milling cutters
PCB micro-drill and micro-milling tool production
Tooling for machining stainless steel, titanium alloys, nickel-based alloys, cast iron, aluminum-magnesium alloys, composites, plastics, and glass fiber reinforced materials
Precision industrial cutting, stamping, and measuring tool applications
Custom carbide rod sourcing where grade, tolerance, and surface finish must be specified by RFQ
How we compare

Custom diameter and length within reported range of approximately 3–35 mm diameter and 50–330 mm length
Polished or unpolished surface finish
H5 or H6 OD tolerance options, subject to supplier confirmation
Ultra-fine, fine, medium, or coarse grain size selection
Trial sample order followed by lot-qualified production order
Courier shipment for small lots or export carton/pallet shipment for larger orders
Human review
Compliance notes
This candidate is an industrial carbide material, not a fine chemical; do not market as a chemical reagent or active chemical ingredient
No CAS number is normally used for a finished cemented carbide rod; if buyer requires material identifiers, request composition-level documentation for tungsten carbide and cobalt binder
Request COA, material certificate, grade datasheet, dimensional inspection report, and packing list for each lot
Cobalt-containing materials may trigger occupational, environmental, or product compliance review in some jurisdictions; buyer should check applicable import and workplace rules
Confirm RoHS, REACH SVHC, conflict minerals, and cobalt sourcing declarations if supplying electronics, tooling, aerospace, or regulated industrial customers
Confirm HS code, country of origin, and export document set before placing the order
DG status should be checked with the supplier and forwarder; solid carbide rods are typically shipped as industrial articles, but dust or powder forms have different hazard considerations
Do not rely on marketplace labels such as audited supplier or warranty as substitutes for technical qualification and compliance documentation

Questions to confirm
What exact grade is being quoted, and what is the cobalt percentage, WC balance, and grain size for that grade?
Can you provide a current datasheet and lot-specific COA showing density, hardness, TRS, grain size, and composition?
What diameter, length, OD tolerance, straightness, roundness, chamfer, and surface roughness can be guaranteed for 300–330 mm rods?
Are the rods ground, polished, or unground blanks, and what inspection method is used for surface finish and dimensions?
Are these made from 100% virgin WC-Co powder as stated, and can this be declared on the material certificate?
What impurity or trace element limits are controlled, especially Fe, Ni, Cr, Mo, Ta, Ti, Nb, and other carbide-forming elements?
What is the minimum order quantity for each diameter and grade, and can mixed-grade or mixed-diameter lots be supplied?
Can you provide sample pieces for incoming inspection before a production order?
