Tungsten carbide buttons feature superior wear resistance and impact toughness, enabling higher drilling and digging speeds. These ball tooth bits offer a significantly longer service life—approximately 5–6 times that of standard grinding head drill bits without requiring sharpening. This durability helps save auxiliary working hours, reduces physical labor, and accelerates project timelines.
| Grade | Applications |
|---|
| YG4C | For electrical and compressed air drill bits in geological prospecting and coal mining. Suitable for coal, unsolidified shale, salt rock, medium hard sandstone, and limestone. |
| YG8 | For coring crowns, electrical coal drill bits, and coal cutting picks in mining operations. |
| YG8C | For rotary rock drill bits (medium soft/hard rock) and coal cutting picks for stone-containing formations. |
| YG11C | For heavy rock drills and rotary hammer rock drills cutting hard rocks. |
| YG13C | For oil field drill cones, rotary percussing bits, and heavy-duty drill bits in hard rock formations. |
| YG15 | High intensity, lower wear-resistance. Ideal for rotary machines in hard and very hard rock formations. |
| YG15C | For manufacturing drill cones used in various rock formations. |

Frequently Asked Questions
What materials are used for these buttons?We use 100% virgin tungsten carbide material to ensure maximum hardness and performance.
Can you customize the sizes?Yes, we can produce buttons according to your specific drawings and dimensional requirements.
What is the advantage of HIP sintering?Hot Isostatic Pressing (HIP) removes internal pores, resulting in superior density and higher impact resistance.
Which grade should I choose for hard rock?For hard and very hard rock, we typically recommend grades like YG15 or YG13C based on your specific application.
Do these buttons require frequent sharpening?No, our buttons last 5-6 times longer than standard bits, significantly reducing the need for maintenance and grinding.
