- Anti-Friction Coating: Premium nano-coating serves as a heat barrier, actively preventing soft metal pick-up or welding.
- Non-Clogging Flutes: Deep, wide Alu Cut channels throw sticky shavings out instantly to avoid tool loading.
- Precise Tapered Cone: 12.7mm ball nose cone shape is ideal for internal radius smoothing and narrow slot deburring.
- Standard 1/4" Shank: Precision-ground fractional shank ensures zero slipping and minimal vibration inside standard collets.
BESKRIUWING
Product Overview
Prevent thermal loading and metal adhesion during non-ferrous metal finishing with our premium Coated Alu Cut Tungsten Carbide Rotary Burr (L12.7*32.28-W-6.35). Designed with a classic Ball Nose Cone Shape (Shape L), this tool is highly efficient for widening narrow gaps, clearing interior curved channels, and edge blending on ductile alloys.
The cutting head features an advanced industrial heat-resistant nano-coating over wide, deeply ground single flutes. This specialized engineering combination ensures rapid chip evacuation, dramatically reduces frictional heat, and eliminates the tool-clogging common when processing sticky materials.

FAQ
1) Wannear kin ik de priis krije?
Wy sitearje normaal binnen 24 oeren nei't wy jo fraach krije. As jo heul driuwend binne om de priis te krijen, belje ús dan asjebleaft of fertel ús yn jo e-post, sadat wy jo ûndersyksprioriteit sille beskôgje.
2) Hoe kin ik in stekproef krije om jo kwaliteit te kontrolearjen?
Nei priisbefêstiging kinne jo samples fereaskje om ús kwaliteit te kontrolearjen. As jo gewoan in lege stekproef nedich binne om it ûntwerp en papierkwaliteit te kontrolearjen, sille wy jo fergees sample leverje, salang't jo de ekspresfracht betelje.
3) Hoe lang kin ik ferwachtsje om de stekproef te krijen?
Nei't jo de samplekosten betelje en ús befêstige bestannen stjoere, sille de samples yn 3-7 dagen klear wêze foar levering. De samples wurde fia ekspresje nei jo stjoerd en komme yn 3-7 wurkdagen. Jo kinne jo eigen express-akkount brûke of ús foarôf betelje as jo gjin akkount hawwe.
4) Hoe lang wurdt de hiele proseduere útwurke?
Nei't jo in bestelling pleatse, is de produksjetiid sawat 20-25 dagen. Wy hawwe 7 dagen nedich om al it spul te meitsjen, dan 15 dagen foar fabrikaazje.
5) Wat oer de transport- en leveringsdatum?
Normaal brûke wy ferstjoering om it guod te transprotearjen. It giet oer 7-25 dagen. It hinget ek ôf fan hokker lân en haven jo binne. It kin koarter wêze as jo it guod lykas Aziatyske stjoere moatte. As d'r wat needgefallen binne, kinne wy it guod fia air express stjoere, salang't jo de ferkearskosten betelje.
6) Binne jo hannelsbedriuw as fabrikant?
Wy binne profesjonele fabrikant. Wy hawwe net allinich ús arkfabryk, mar hawwe ek cemented carbide fabryk.
7) Wêr leit jo fabryk?
Wy binne fêstige yn Zhuzhou stêd, Hunan Provinsje., wolfraam carbid basis stêd fan Sina
8) Hoe lang kin ik ferwachtsje om de stekproef te krijen?
Nei't jo de samplekosten betelje en ús befêstige bestannen stjoere, sille de samples yn 3-7 dagen klear wêze foar levering. De samples wurde fia ekspresje nei jo stjoerd en komme yn 3-5 wurkdagen. Jo kinne jo eigen express-akkount brûke of ús foarôf betelje as jo gjin akkount hawwe.
