General Information

- Furukawa OEM Model
- Explanation
-
- Unlike conventional leg drills designed primarily for maximum drilling speed, the BRD322D features a sound balance between the pusher leg and the drill. This ensures stabilized operation through a wide range of drilling angles. Moreover, the pusher leg absorbs the drilling vibrations very effectively that the operator can use it for many hours of speedy drilling operation without excessive fatigue. Another feature is the concentration of all controls on the back head of the drill. This enables the operator to control the drill quickly and easily. The pusher leg is as light-weight as it can be.
- Advantage
-
- Release Valve and Stop Plunger
Pressing the stop plunger on pusher Leg is a safety device that completely shuts off the air supply, so that the pusher leg can be adjusted stably without turning the feed control valve. It is very useful in emergency stops and can prevent safety accidents. - Air-Compressed Pawl
The 322D pawl is compressed by air, and does not require a pawl plunger and pawl spring. It is economical because all four sides can be used in a square shape of wear-resistant material. - Perfect Balance of Drill and Pusher Leg
The drill recoil is absorbed by the leg owing to the integral design of the pusher leg and drill and consideration has been given to constantly produce full power. - Performance Equal to Air Flushing
The automatic water-feed device and the constant impact and lubricating mechanisms serve to give the same performance as a comparable drill with air flushing. - Adaptable to Long-hole Drilling
Long-hole drilling is possible with BRD322D’s powerful impact mechanism and strong rotating force, and it is equally efficient in drilling also of small-diameter holes. - Automatic Water-feed Device
Water is instantly fed automatically as soon as the drill is started by working the throttle valve handle, and is automatically stopped when the drill operation ceases. Powerful blows can be effected by means of the same handle.
