Hertel C.E10.1746 Extra Length Drill Bit 11/16 in Hss

Product Description

The HERTEL C.E10.1746 is an extra length high-speed steel drill bit designed for deep-hole drilling applications where standard-length bits cannot reach. It measures 11/16 inches (0.6875 inches) in diameter with a 12-inch overall length and a 9-inch flute length, giving tradespeople the reach needed to bore through thick stock, structural members, or deep assemblies. The 118-degree split point angle is a general-purpose geometry suited for a wide range of materials including mild steel, aluminum, wood composites, and plastics. An oxide finish reduces friction and provides light corrosion resistance during storage and use.

This drill bit is used in construction, mechanical contracting, fabrication, and maintenance applications where access depth is a constraint. Electricians boring long runs through framing, plumbers drilling through multiple joists or headers, and HVAC technicians routing through structural material all benefit from the extended flute and shank length. The two-flute design clears chips efficiently during extended-depth cuts, reducing heat buildup and bit deflection on long-reach operations.

Key Features

• 11/16 inch diameter with 0.6875 inch decimal equivalent for precise sizing
• 12-inch overall length provides reach beyond standard jobber-length bits
• 9-inch flute length supports chip evacuation on deep-hole passes
• 118-degree drill point angle suits general-purpose materials including steel, aluminum, and wood
• High-speed steel construction withstands heat generated during extended drilling cycles
• Oxide finish reduces friction and offers light corrosion protection

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard 3-jaw drill chucks and magnetic drill presses accepting straight-shank bits in the 11/16 inch size range.

Installation Notes

This bit is installed and used by electricians, plumbers, HVAC technicians, and general contractors using standard corded or cordless drills with sufficient torque and chuck capacity. Secure the workpiece before drilling and use appropriate cutting fluid when boring through ferrous metal to extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present. Follow applicable safety codes and wear eye protection during all drilling operations.
