Hertel C.E11.0833 Extra Length Drill Bit 0.3281 in Hss

Product Description

The HERTEL C.E11.0833 is an extra length high-speed steel drill bit designed for deep-hole drilling applications where standard-length bits cannot reach. It measures 0.3281 inches in diameter, carries a 118-degree split point, and delivers a flute length of 12 inches within an 18-inch overall length. The oxide finish reduces friction and helps resist heat buildup during extended drilling cycles. With two flutes and a general-purpose grade designation, this bit handles a wide range of ferrous and non-ferrous materials in production and maintenance environments. Machinists, millwrights, pipefitters, and tool-and-die professionals are the primary users.

This extra length drill bit is suited for applications requiring reach beyond the capacity of jobber-length tooling. Typical uses include drilling through structural steel, pipe walls, deep flanges, heavy plate, and assemblies where standard drill lengths fall short. The 18-inch overall length makes it practical for drilling through stacked materials or accessing recessed bores in fabrication, mechanical contracting, and industrial maintenance settings. It is sold individually and fits standard drill chucks compatible with its shank diameter.

Key Features

• 18-inch overall length for deep-reach drilling beyond standard jobber-length capacity
• 12-inch flute length supports chip evacuation throughout deep-hole cuts
• 118-degree drill point angle suited to general-purpose ferrous and non-ferrous drilling
• High-speed steel construction maintains hardness under elevated cutting temperatures
• Oxide finish reduces surface friction and provides light corrosion resistance
• Two-flute design provides a balance of chip clearance and cutting edge rigidity

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks and drill presses that accept a 0.3281-inch shank diameter.

Installation Notes

This bit is installed by machinists and maintenance trades using drill presses, magnetic drills, or hand-held drill motors. Secure the bit fully in the chuck and verify runout before beginning the cut. Use appropriate cutting fluid for the material being drilled, especially in long-reach operations where heat accumulation is a concern. Reduce feed rate as the bit approaches full depth to avoid bit deflection and premature wear.
