Hertel C.E10.0556 Extra Length Drill Bit 7/32 in Hss

Product Description

The HERTEL C.E10.0556 is an extra length high-speed steel drill bit designed for drilling applications that require extended reach beyond what a jobber-length bit can provide. Sized at 7/32 inch (0.2188 inches) in diameter, it features a 118-degree standard drill point and a straight shank for use in standard drill chucks. The oxide finish provides a degree of corrosion resistance and reduces friction at the cutting edge. With a 9-inch flute length and a 12-inch overall length, this bit is suited for deep-hole drilling in metal, wood, and general-purpose materials.

This bit is a general-purpose grade tool intended for production and maintenance drilling where stock material length is a limiting factor. It is commonly used by machinists, maintenance technicians, and fabricators working on structural components, ductwork, frames, or other assemblies where a standard-length bit cannot reach the target depth. The straight shank fits standard three-jaw chucks on drill presses, hand drills, and magnetic base drills.

Key Features

• 7/32 inch (0.2188 inches) diameter for precise hole sizing
• 12-inch overall length for extended reach applications
• 9-inch flute length for deep-hole chip evacuation
• 118-degree standard drill point for general-purpose materials
• High-speed steel construction for durability and regrindability
• Oxide finish reduces friction and provides light corrosion resistance

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard three-jaw chucks accepting straight shank tooling in the 7/32 inch diameter range.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or technician familiar with rotary cutting tools. Secure the straight shank fully in the drill chuck before operation and verify runout before drilling. Always use appropriate cutting fluid when drilling ferrous metals to extend tool life and improve hole finish. Wear appropriate PPE including eye protection whenever operating drilling equipment.
