Hertel C.E11.0913 Extra Length Drill Bit 0.3594 in Hss

Product Description

The HERTEL C.E11.0913 is an extra length twist drill bit designed for through-hole and deep-hole drilling in metal, wood, and general-purpose materials. It measures 0.3594 inches in diameter with an 18-inch overall length and a 12-inch flute length, giving it extended reach for applications where a standard-length bit cannot access the work zone. The 118-degree split or conventional point geometry provides reliable self-centering on most common materials. The high-speed steel (HSS) construction with an oxide finish resists heat buildup during continuous cutting and extends service life under moderate-duty conditions. Machinists, pipefitters, and maintenance technicians are the primary users of this bit class.

Extra length drill bits like the C.E11.0913 are commonly used when drilling through thick structural members, deep-set flanges, long pipe sections, or stacked materials that exceed the reach of standard jobber-length bits. The extended flute length aids chip evacuation during deep passes, reducing the need for frequent peck cycles. This bit is suited for use in drill presses, magnetic base drills, and hand-held power drills with adequate chuck capacity. It fits standard 3/8-inch or larger keyless and keyed chucks.

Key Features

• 0.3594-inch diameter for precise fractional sizing in general-purpose applications
• 18-inch overall length provides extended reach beyond standard jobber-length bits
• 12-inch flute length promotes chip evacuation in deep-hole drilling
• 118-degree point angle offers broad compatibility with common work materials
• High-speed steel construction maintains cutting edge integrity under heat
• Oxide finish provides mild lubricity and corrosion resistance during storage and use

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks accepting shanks at the stated 0.3594-inch diameter; fits 3/8-inch and larger keyed or keyless chucks on drill presses, magnetic drills, and handheld power drills.

Installation Notes

Secure the bit fully in the chuck and verify runout before beginning a cut. De-energize and lock out the drilling equipment before changing bits. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend bit life and reduce heat. Observe applicable OSHA machine guarding requirements and wear appropriate eye protection during operation.
