Features
High Reliability and
Proven Performance
NEW SUPER DRILL SUPER DRILL was put on the market by SHOWA TOOL CO. more than 20 years ago. Since that time, it was continuously improved through in-the-field experiences. In responce to customer's demands, NEW SUPER DRILL has been developed to increase its flexibility, employing a modular system. The basic set consists of a head and a shank. And, extension arbors are added for deeper holes. SUPER DRILL's ease-of-use is further enhanced by this modular construction.
Single Pass, precision boring of 50mm-270mm diameters
 No center drilling or pilot hole required. Super Drill's built-in center drill acts as an axis for precision drilling.
New Super drill is available in 10 standard head sizes, A1S-55, A2-65, B-80, C-100, D-120, E-150, F-180, G-210, H-240 and I-270, for drilling 50mm to 270mm diameters.

 Specialty of deep hole drilling
 Combination of roughing and finishing blades form small chips, providing efficient chip removal. No pecking or dwelling required, even for deep holes.

 Able to drill even in hard metals
 New Super Drill cutting blades are manufactured from sintered HSS, providing excellent drilling performance even in hard metals.

 Reusable blades and center drill
 The cutting edge of New Super Drill consists of a center drill, a roughing(R) blade and a finishing(S) blade. Different diameter of holes can be bored by changing blades within the capacity of each drill holder.
The blades and center drill can be resharpened which reduces tool cost.
Re-sharpening fixture Re-sharpening fixture

A pair of roughing and finishing brades can be resharpened utilizing the resharpening fixture on the surface grinder.
Oil ring Oil ring

Oil ring is used to supply coolant through the drill in rotational applications.
T/C Guides T/C Guides (for through hole)

In case of through hole drilling, the drill may vibrate immediately before breaking through, depending on hole diameter, cutting speed and feed rate, and rigidity of the machine spindle. This can result in damage of the cutting blades. Using T/C guides when boring through holes will minimize vibration and help prevent tool damage.
Sharpening the blades Sharpening the blades
  1. "R" and "S"blades are ground to the same height.
  2. Both blades are ground in straight line. making first and second clearance.
  3. Grind the center drill to the point angle of 140° with thinning.
