OKAZAKI NC Spotting Drill Bit (Point Angle 90°) Model NPD140-090 Size 14.0 mm.

The OKAZAKI Model NPD140-090 is an extra-large NC starting drill manufactured by OKAZAKI SEIKI, Japan. Made from cobalt high-speed steel (HSS-Co / HSCO), it is designed for spotting applications requiring maximum stability and strength before actual drilling. With its large diameter of 14.0 mm., it is ideal for preparing large holes, ensuring 100% hole positioning accuracy and reducing drill walking or deflection on high-hardness workpieces.

90° Point Angle: The 90-degree point angle is the standard angle that allows the main drill bit tip to center easily, and it is also well-suited for chamfering large countersunk screws.

Premium Cobalt HSS: Cobalt-alloyed material provides excellent heat resistance and retains a sharp cutting edge longer, even when machining difficult-to-cut materials.

Maximum Rigidity: With a 14 mm. shank size and a short body, it delivers extremely high rigidity, dampening vibration at the start of drilling much better than smaller models.

Japanese Precision: Manufactured under Japanese Industrial Standards (JIS), ensuring confidence in symmetry and accuracy.

Large Hole Spotting: Used for hole spotting of large-diameter holes on CNC or milling machines

Heavy Duty Chamfering: Used for hole deburring or 90-degree chamfering in heavy engineering applications

Workpiece Materials: Performs well on various materials such as tool steel, cast iron, stainless steel, and alloy steel
