NACHI 0798890 9.90mm Size 135° Solid Carbide Screw Machine Length Stub Drill Low Price

Since founding, Fujikoshi has considered that superior materials are necessary to make better tools, has been researching and developing in-house, and in-house manufacturing tools. Based on this idea, we developed carbide materials this time. In addition, the AquaREVO Drill is used not only for super hard Materials, shape, refreshing the coating, such as long tool life, high efficiency, multipurpose, all functions required for drilling have been dramatically improved.

Applications

• Dramatically improves all functions of drilling.
• Development of a carbide material adds both hardness & toughness.
• Improves wear resistance and chipping resistance.
• New straight cutting edge breaks up cutting stress.
• Newly developed REVO-D coating suitable for drilling multiple materials.
• Improved strength against corner chipping.

Features

New Material

• Development of carbide base material compatible with hardness and toughness.

New Shape

• Adoption of straight cutting edge.
• Break up cutting stress.
• Improving wear resistance and chipping resistance.

New Coating

• Newly developed REVO-D coat suitable for drilling.
• High oxidation resistance and wear resistance ensured.
• Realizes low friction and smooth chip evacuation by super smooth surface treatment.

Technical Data

• The C-Point angle improves location and size accuracy and helps prevent too-walking during the drilling process by maintaining its position.
• The R-Edge or radius-edge changes the vertical cutting force of a traditional drill into a side/radial force similar to that of an end mill. This eliminate the burr from being pushed down, and is instead, trimmed off in a radial direction during drill exit.
