SHANDIKE has a comprehensive range of DTH drill bits to match all conceivable applications. Each bit is made from quality alloy steel, and has been precision machined to produce a perfect body, heat treated to the required hardness, given surface compression for fatigue resistance, and fitted with precision buttons manufactured in-house. These are deigned for specific applications for all rock types, hardness’s and condition. Bit life and rate of penetration are the most important criteria in selecting the right bit for a particular application.
 |
Drop Center For high penetration rates in soft to medium hard and fissured rock formations.Low tomedium air pressures.Maximum hole deviation control. |
 |
Concave Face The all-round application bit face specifically for medium hard and homogenerous rockformations.Good hole deviation control and good flushing capacity. |
 |
Convex Face For high penetration rates in soft to medium-hard with low to medium air pressures.It isthe most resistance to steel wash,and may reduce the load and wear on the gaugebuttons,but poor hole deviation control. |
 |
Double Gauge Face This kind of face shape is suitable for fast penetration rates in medium to hard rockformations.Designed for high air pressures and good resistance to steel wash step gaugebit. |
 |
Flat Face The Pineapple Bit can be dressed with ballistic buttons for use in soft to medium hard |
 |
Pineapple Face The Pineapple Bit can be dressed with ballistic buttons for use in soft to medium hardformations where fractured rock can be expected,or can be supplied with spherical buttonsfor hard and abrasive formations. |
