Hertel C.E10.1032 Extra Length Drill Bit 0.4062 in Hss

Product Description

The HERTEL C.E10.1032 is an extra length twist drill bit engineered for deep-hole drilling applications where standard-length bits cannot reach. Built from high-speed steel (HSS) with an oxide finish, this bit measures 0.4062 inches in diameter and carries a 118-degree point angle suited for general-purpose drilling in a wide range of materials. The flute length runs 9 inches and the overall length reaches 12 inches, providing the extended reach required for thick workpieces, deep bores, or drilling through structural assemblies. Two flutes clear chips efficiently along the full flute length. Machinists, maintenance technicians, and trade professionals working with metal, plastics, or composites install this bit in standard drill chucks and drill presses.

This extra length drill bit is used in residential and commercial maintenance, mechanical contracting, fabrication shops, and industrial service environments. The extended overall length of 12 inches makes it practical for applications such as drilling through wall studs, pipe flanges, heavy plate, and other deep or obstructed workpieces where a jobber-length bit would bottom out before completing the bore. The general-purpose grade makes it a versatile stock item for shops and service vans handling varied drilling tasks across steel, aluminum, and similar materials.

Key Features

• 0.4062 inch diameter with a 118-degree split-compatible point angle for general-purpose use
• 12 inch overall length provides extended reach beyond standard jobber-length bits
• 9 inch flute length supports deep-hole chip evacuation
• High-speed steel construction handles a broad range of metals and materials
• Oxide finish provides light corrosion resistance and reduces friction during drilling
• Two-flute design maintains straightforward sharpening compatibility

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks, drill presses, and handheld drills accepting 0.4062 inch round shanks.

Installation Notes

This bit is installed by machinists and trade professionals using standard drill chucks rated for the shank diameter. Secure the bit fully in the chuck and verify concentricity before beginning a bore. Due to the extended length, use reduced feed rates and ensure the workpiece is firmly fixtured to minimize deflection and bit breakage. Cutting fluid or lubricant is recommended when drilling ferrous metals to extend tool life.
