| 1.1 Our fan blades are super tough and durable | ||
| 2.1 The commutator is made of silver-copper alloy, so it is wear resistant. The height of the commutator can be 13.39mm, which is higher than regular products (12mm), so the safety performance is greatly increased. | ||
| 3.1 The length of engagement has reached 17.8mm, making the gear more durable and Powerful. | ||
| 4.1 The bearings in the air cylinder chamber of the gearcase is plastic packed skeleton bearings which is grease resistant and durable. | ||
| 5.1 The 33mm thickened air cylinder comes with a more fluent air distribution system, The hammering actions are more Powerful. | ||
| 6.1 The patented structure - lengthened thread and spring snap mechanism, can prevent the cover from loosing, even being drastically shaking. | ||
| 7.1 The gear is made of 20CrMnTi, which is highly tough and wear resistant. The surface harness can be HRC58. | ||
| 8.1 The brush holder is made of copper. | ||
| 9.1 The varnished wire and the axis are both well insulated, so the electric leakage risk is greatly reduced. | ||
| 10.1 The stator coils are fixed by steel discs witch can effectively protect the coils from moving up and down when the rotary hammer drill is vibrating, thus the motor can be also well protected. | ||
| 11.1 Our rotary drill uses 3C certified wires which have YCW on the surface. | ||
