Ok280 pneumatic drill

Features

The BM 280-LD Leg Drill with an outstanding drilling performance is most suited for quick drilling operation. lts strong percussion and torque ensure a high-speed drilling in rock of any formaion. All parts are highly durable and hard-wearing, resulting in less spare parts cost as well as enabling the drill to maintain its high performance for a long period of time. in addition, as the dirll and the leg are very well balanced, highly stabilized operation and minmum of recoil are to be appeciated. Therefore, this lmodel will accelerate the drilling speed and will reduce the operator`s fatigue and the cost of drilling.

1.Outstanding Drilling Speed

The BM 280-LD, using a 3" -bore cylinder and a tubular valve with high air efficiency, produces strong percussion and torque and performs marvellously in drilling hard rock as well as semi-long hole.

2.Ease of Operation

A good balance between the drill and the leg ensures a stabilized operation with less recoil. Besides, the exhaust deflector can be oriented in ay direction to keep the exhaust air out of the operator`s way.

3. Durability and Continued High Performance

The external parts of the drill of special steel possess high rigidity and surface hardness, and the hard working internal parts are sufficiently lubricated, so the service life of parts is extended, resulting in a substantial saving in spare parts cost.

4. Light Support Leg Providing Stable Feed Pressure

The SL-40L Support Leg is designed to match ideally with this type of drill so that the drill will fully display its performance. Made of super duralumin, the leg is light in weight and ver easy to handle.
