Cleveland C70330 Screw Machine Drill Bit Wire 26 Hss

Product Description

The CLEVELAND C70330 is a screw machine length drill bit designed for high-production drilling applications where stub-length rigidity and accurate hole placement are required. Built from high-speed steel with a bright/uncoated finish, this bit features a 135-degree split point that reduces walking and cutting thrust at entry. The 0.1470-inch diameter corresponds to wire gauge size 26. With an overall length of 2-1/16 inches and a flute length of 1 inch, the shortened geometry delivers added stiffness compared to jobber-length alternatives, making it well suited for drill press and CNC work on close-tolerance hole patterns.

This bit is rated for use in alloy steel and aluminum workpieces and carries an NAS 907 Type C specification designation, making it appropriate for aerospace and industrial manufacturing environments. The web-thinned, parallel-web construction reduces cutting resistance, which extends tool life in repetitive drilling cycles. Machinists, tool-and-die makers, and production drilling technicians working on precision assemblies or structural components will find it a reliable straight-to-size option for wire gauge hole requirements.

Key Features

• 135-degree split point reduces entry walking and lowers required feed force
• Screw machine (stub) length provides superior rigidity over jobber-length bits
• Web-thinned parallel web reduces cutting resistance and heat buildup
• High-speed steel construction handles alloy steel and aluminum workpieces
• Right-hand cut, straight-cylindrical shank fits standard drill chucks and collets
• Meets ASME B94.11M and NAS 907 Type C specifications for industrial and aerospace use

Compatibility

Designed as a direct-fit replacement for wire size 26 screw machine length drill bits in standard drill chucks, collet holders, and quick-change tool systems accepting a 0.1470-inch straight-cylindrical shank.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or tool operators familiar with safe drilling practices. Ensure the drill chuck or collet is fully tightened and the workpiece is securely fixtured before beginning the cut. Always power down and de-energize the machine before changing tooling. Follow the machine manufacturer and applicable shop safety guidelines regarding speeds and feeds for the workpiece material.
