Hertel 61699286 Screw Machine Drill Bit 13 Wire Hss

Product Description

The HERTEL 61699286 is a screw machine length drill bit designed for general-purpose drilling in metal, wood, and similar materials. It is sized to wire gauge number 13, which corresponds to 0.185 inches in decimal. The bit is manufactured from high-speed steel with an oxide finish for added surface protection and reduced friction. The 118-degree standard point angle suits a wide range of common drilling applications. With an overall length of 2.1875 inches and a flute length of 1.125 inches, this stub-length geometry provides increased rigidity and resistance to deflection compared to jobber-length bits. It is installed and used by machinists, maintenance technicians, and general trade professionals.

This drill bit is suited for production and maintenance drilling tasks where a shorter, stiffer bit is preferred over standard jobber-length tooling. The screw machine length format is common in drill press and hand-drill applications where hole depth is limited and bit stability is a priority. The right-hand cutting direction and straight cylindrical shank make it compatible with standard three-jaw drill chucks found in most handheld and bench-mounted drilling equipment. The 3xD flute-to-diameter ratio supports adequate chip evacuation in typical general-purpose drilling scenarios.

Key Features

• Wire gauge size 13 with a decimal diameter of 0.185 inches
• 118-degree standard point angle for general-purpose entry on flat and curved surfaces
• High-speed steel construction with oxide coating for surface protection
• Screw machine length geometry provides greater rigidity than jobber-length bits
• Right-hand cut with straight cylindrical shank fits standard drill chucks
• Two-flute regular spiral design promotes chip removal during drilling

Compatibility

Designed as an OEM-style general-purpose drill bit compatible with standard three-jaw drill chucks accepting a straight cylindrical shank in the applicable diameter range.

Installation Notes

This bit is installed and operated by machinists and general maintenance technicians using handheld drills or bench-mounted drill presses. Ensure the chuck is fully tightened and the workpiece is properly secured before operation. Use appropriate cutting fluid when drilling ferrous metals to extend tool life. Always wear eye protection and follow applicable shop safety standards when operating rotary cutting tools.
