What are the benefits of HAIRUITE-mining Pick?
Our advanced brazing techniques and precision cold-formed body design ensure even wear distribution,enhanced rotation,and a longer tool lifespan.With superior head hardness and a design that redirects debris away from sensitive parts,our picks promote reliable,efficient cutting with reduced vibration and minimal risk of damage.
How do our mining products compare to competitors?
Independent field tests in China coal mines show that HRT cutting picks boost performance by 20%-30%.They increase tonnage per pick,reduce downtime,and enhance productivity due to their design and efficient handling of different coal strengths.This results in big cost savings for your customers.
Are HAIRUITE-Mining cutting pick compatible with all mining machines?
Yes,Our range of mining cutting teeth are compatible with all major underground and surface mining machines,including continuous miners,longwall shearers,and roadheaders.
Can I order custom sized mining picks and sleeves?
Yes,if you don't find a product that meets your requirements,we can manufacture custom solutions based on your specifications.Alternatively,our technical mining applications team can visit your site to recommend the most suitable cutting teeth for based on specific needs.
What are the lead times and stock availability at HAIRUITE?
Lead times for manufacturing and delivery depend on order size and any customization needs.We keep strategic stock levels of key mining carbide cutting picks to ensure fast response times for urgent orders.Once an order is placed,we will provide a specific timeline to meet your operational demands efficiently.
Why dose HAIRUITE cold forge our cutting teeth?
HRT uses cold forging to produce cutting teeth with a denser grain structure,resulting in superior durability,precision,and a smoother surface finish.This process offers better strength and performance than hot forging,making it ideal for demanding applications.
