Hertel 61699302 Screw Machine Drill Bit 0.261 in Hss

Product Description

The HERTEL 61699302 is a screw machine length drill bit designed for general-purpose drilling in metal, wood, and similar materials. Built from high speed steel with an oxide finish, it delivers reliable performance in production and maintenance environments. The 118-degree standard point angle suits a wide range of materials and is the most common configuration for general shop use. At 2.625 inches overall length with a 1.4375-inch flute length, this short-body design reduces deflection and improves rigidity in drill presses, lathes, and CNC machines. It is sold as a single bit and weighs 0.13 pounds.

Screw machine length drill bits are used wherever a shorter, stiffer drill is preferred over a jobber-length bit. This bit is well suited to machine shop applications, production drilling, and maintenance repair operations. The right-hand spiral flute evacuates chips efficiently during through-hole and blind-hole drilling. The straight cylindrical shank fits standard three-jaw drill chucks without modification. Letter size G corresponds to 0.261 inches decimal diameter, placing it in the 0.25 to 0.30 inch size range.

Key Features

• High speed steel construction with oxide finish for corrosion resistance and reduced friction
• 118-degree standard point angle for general-purpose use across a broad range of materials
• Screw machine length body reduces deflection and improves hole accuracy
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Straight cylindrical shank compatible with standard drill chucks
• ANSI specification designation confirms dimensional conformance

Compatibility

Designed as a general-purpose screw machine length drill bit in letter size G, compatible with any standard drill chuck or collet that accepts a straight cylindrical shank in the 0.261-inch diameter range.

Installation Notes

Installation of this drill bit is performed by machinists, tool-and-die workers, and maintenance technicians using drill presses, lathes, or CNC equipment. Secure the shank fully in the chuck and confirm runout before drilling. Always wear appropriate eye protection and secure the workpiece before operation. Follow applicable shop safety procedures and equipment manufacturer guidelines when selecting feeds and speeds for the material being drilled.
