| Features | 1.Professional quality for efficient and fast hammer drilling in
hard materials like concrete, granite, brick and other similar
building materials. 2.Premium carbon steel with heat treatment improves core strength
for maximum durability and extended life. 3.4 Cutters head design oprates with less noise than standard cutter
heads and produces about 60% less vibration while lasting about
50%. 4.Copper braze material gives high heat resistance for reduced tip
loss,Carbide tip securely embedded in the steel body. 5.4-fold spiral flute (S4) for rapid drilling dust removal. With even
less vibration and more precise guiding, the stability and service
life of the drill bit are increased. 6.Wear mark identifies when bit has worn to an inappropriate level
for precision anchoring. 7.Compatible with all SDS-Max style chucks. |

Production and test of tungsten carbide cross big bit tips for drilling stainless steel
hard material
1, After the order is confirmed,TC carbide cross tips will start to
prepare the RTP powder as per customer’s requirement with our
wet-grinding machine
2, Before mass production, we need to do a trial pressing and
sintering using every mould, and we check the appearances and the
sizes of the samples with micrometer, projectors etc. to ensure
that the requirements of the drawings can be met before batch
production
3, Bulk production ,press the raw materials to shape blanks,and all
TC carbide cross tips must be passed by semi finished inspection.
4, Then sinter blanks to finish (HIP) and finished products
inspection, we have 10 sets of vacuum sintering furnace and 2 sets
of HIP in the factory ensure the best quality and production
capacity.
Packing and delivery of Good impacting carbide cross big bit tips for drilling concrete and
steel
step 1, wrapped TC carbide cross tips in paper to avoid TC carbide
cross tips to broke
step 2, put the TC carbide cross tips in inner small carton box
step 3, put the inner box into outter carton and fill the carton
with foamed plastic
step 4, wrap the carton with packaging tape
step 5, you can choose any delivery way such as DHL,TNT,UPS ect.
