Hertel C.E09.0833 Extra Length Drill Bit 0.3281 in Hss

Product Description

The HERTEL C.E09.0833 is a general-purpose extra length drill bit ground from high-speed steel (HSS) with an oxide finish. It carries a 0.3281-inch diameter, a 118-degree drill point angle, and a 10.0000-inch overall length, giving it the reach needed for deep-hole drilling applications where a standard-length bit falls short. The two-flute geometry clears chips efficiently during through-hole operations. Machinists, maintenance technicians, and fabricators working in metalworking, HVAC fabrication, and industrial assembly rely on this bit when clearance or material depth demands extended tool reach beyond conventional lengths.

This extra length drill bit is suited for general-purpose drilling in metal, ferrous materials, and similar substrates encountered in production and maintenance environments. The 7.5-inch flute length accommodates significant material depth, making it a practical choice for structural drilling, deep fixture work, and situations where a standard or jobber-length bit cannot reach the target bore location. Sold individually, it fits directly into standard drill chucks and magnetic drill press setups used in field and shop applications.

Key Features

• 0.3281-inch diameter for precise hole sizing in metalworking and fabrication tasks
• 118-degree drill point angle — a standard geometry suited for general-purpose drilling in steel and similar metals
• 10.0000-inch overall length provides extended reach beyond jobber-length tooling
• 7.5-inch flute length supports deep-hole chip evacuation
• High-speed steel construction resists heat buildup during continuous drilling operations
• Oxide finish offers a basic level of corrosion and abrasion resistance

Compatibility

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

Installation Notes

Installation and use should be performed by machinists or qualified trades personnel familiar with drill press and portable drilling equipment. Secure the workpiece firmly before drilling to prevent rotation and bit deflection. Confirm chuck tightness and verify the drill point is properly centered before beginning a cut. Use appropriate cutting fluid for the material being drilled to extend tool life and maintain hole quality.
