Water Resistant
The motor ventilation system is designed to prevent water from flowing inside the motor while keeping effective air cooling capacity.
Dymodrill Series
Our Concept
Demands from clients have often contradicted with engineering possibilities. However, Shibuya has made every effort to knuckle down to achieve them. The keyword is “NO COMPROMISE” believing that we can overcome the difficulties without sacrificing anything.
High Durability With Light Weight
Utilizing advanced molding technology, pressurized die-casting and plastic injection reduced external parts’ weight. To reduce the weight inside the gearbox, holes are drilled in every possible gear, the slip discs for the clutch are relocated at the recess of gear, and the spindle shaft has a hollow structure. All these weight reductions can be achieved without sacrificing any durability. 40 years of experience in making diamond core drilling machines have made all these possible.
High Power From Small Sized Motor
Many have asked us why Shibuya core drill machines use low power, and whether they have what it takes to do proper coring work. The concept of power is often misunderstood. The torque of the SHIBUYA machine with 1500W is much more than many machines with higher rated input. Low power also ensures the motor operates efficiently on all sites and domestic power supplies, while surplus power acts as a safety margin to extend armature life.
Hybrid Column
The Hybrid Column uses an outer layer made of steel and an inner layer made of aluminum. Steel gives durability against wear and supports metal guide rollers for higher rigidity, while the aluminum inner core increases strength and stability while reducing weight.
Carriage Block
The motor’s carriage block runs on durable steel rollers instead of the friction plates used in older models. This reduces drag, abrasion, and wear on the carriage block and column while giving smoother feeds and higher rigidity.
Features
Less Noise With High Cooling Capacity
The noise level achieved with these models is 84db(A) at no load. Not only has noise been reduced, the motor tone is tuned. A new plastic cooling fan and improved motor enclosure direct available air to the components that must be kept cool.
Drill Stand
Choose between angle stand or fixed stand. Rotate the core drill on its base up to 45 degrees for angled drilling and secure the column at the desired angle with a simple turn of a wrench.
Feed Handle
Move the feed handle to the right or left side with ease to suit different working conditions. No tools necessary.
Water Inlet Valve
The water inlet valve swivels 360 degrees to allow easy water hose connection even in tight workplaces.
Circuit Protector
The circuit protector is conveniently located on the drill and features motor overload protection.
PRCD
PRCD cuts off the electricity when it detects electric leakage.
