Hertel C.E09.0635 Extra Length Drill Bit 1/4 in Hss

Product Description

The HERTEL C.E09.0635 is an extra length high-speed steel drill bit designed for boring operations that require deeper reach than a standard-length bit provides. Ground to a 118-degree point angle, it suits general-purpose drilling in a wide range of metals, wood, and plastics. The 1/4-inch diameter body runs a 7.5-inch flute length with a 10-inch overall length, giving tradespeople and machinists the clearance needed to reach recessed bore locations or drill through thick stock in a single pass. An oxide finish reduces friction and provides modest corrosion resistance during normal shop use.

This bit is suited for metalworking, fabrication, mechanical contracting, and maintenance applications where standard-length bits cannot reach the workpoint. It fits any 1/4-inch-capable drill chuck, including portable hand drills, drill presses, and magnetic base drills. The two-flute geometry evacuates chips efficiently in through-hole and deep-hole applications. General-purpose grade makes it appropriate for carbon steel, aluminum, brass, wood, and similar materials encountered in HVAC, plumbing, electrical, and general mechanical work.

Key Features

• 10-inch overall length for deep-reach drilling in thick stock or confined spaces
• 7.5-inch flute length promotes chip evacuation on deep passes
• 118-degree split-point-style angle suitable for general-purpose materials
• High-speed steel construction withstands heat generated during prolonged drilling cycles
• Oxide finish reduces surface friction and light corrosion during storage and use
• Two-flute design compatible with standard drill chucks accepting 1/4-inch shank

Compatibility

Designed as a general-purpose extra length drill bit compatible with any drill press, hand drill, or magnetic base drill equipped with a chuck that accepts a 1/4-inch round shank.

Installation Notes

Install and remove drill bits only when the drill or drill press is powered off and the spindle is fully stopped. Secure the bit firmly in the chuck and verify there is no runout before drilling. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Wear safety glasses and secure the workpiece; extra length bits are more susceptible to deflection at high speeds, so use the lowest effective RPM for the material.
