One of our customers from Malaysia are buying T38 & T45 top hammer rock tools from us, Mr Thiru, an active, very kindly, experienced and knowledgeable young man, and his father own several drilling rigs & iron ore mines, and their main order list are as follows:

Button bit T45 89mm (3-1/2″) (Spherical)

T45 extension rod 12ft with spanner groove

T45 shank adapter HD712 (790mm)

Coupling sleeve T45

T38 button bit 64mm (2-1/2″) (Spherical)

Coupling adapter thread A (T38) ~ thread B (T45)

T38 76mm (3″) button bit

T38 extension rod 10ft

But it’s a failure feedback case from their sites in Malaysia at the start stage for us, as it’s very hard to unpack & remove the T45 extension rod 12ft with spanner groove with T45 coupling sleeves, the main problem is the high precision of the T45 thread standard, the tolerances is too small. After adjustment, we solved such problem and quality improved. Also we designed the T45-89mm spherical button bits for him specially, fully customized according to their requirements for the tungsten carbide diameter & numbers with best working life. Until now, they are buying from us regularly with large quantity every month.
