Hertel C.E10.0754 Extra Length Drill Bit 0.2969 in Hss

Product Description

The HERTEL C.E10.0754 is an extra length twist drill bit designed for deep-hole drilling applications where a standard-length bit cannot reach. Ground from high-speed steel (HSS) with an oxide finish, it measures 0.2969 inches in diameter, carries a 118-degree split-point angle, and delivers a 9-inch flute length within a 12-inch overall length. The two-flute geometry maintains chip evacuation through extended cuts. Machinists, maintenance technicians, and trade professionals working in metal fabrication, HVAC equipment assembly, or mechanical service use this bit with standard drill chucks when access depth is the limiting factor.

This bit is suited for general-purpose drilling in ferrous and non-ferrous metals, plastics, and similar materials where extra reach is required. Typical applications include drilling through deep structural members, long equipment housings, or stacked assemblies that exceed the reach of jobber-length bits. The oxide finish provides a degree of surface lubricity and corrosion resistance during normal use. It fits any standard drill chuck accepting a 0.2969-inch shank and is sold individually.

Key Features

• High-speed steel construction for general-purpose metal drilling durability
• 118-degree point angle for reliable centering and clean entry on a wide range of materials
• 9-inch flute length supports chip clearance through deep cuts
• 12-inch overall length provides extended reach beyond standard jobber-length bits
• Oxide finish adds surface lubricity and light corrosion resistance
• Two-flute design balances cutting efficiency with rigidity at extended length

Compatibility

Designed as a general-purpose extra length drill bit compatible with any standard drill press, mill, or handheld drill chuck accepting a 0.2969-inch round shank.

Installation Notes

Secure the bit firmly in the chuck before operation and verify there is no runout before beginning a cut. Use cutting fluid or appropriate lubricant when drilling ferrous metals to extend bit life and improve hole finish. Reduce feed rate on breakthrough to prevent grabbing or bit deflection at extended length. Inspect the cutting edges for wear before each use, as HSS bits at extra length are more susceptible to deflection under excessive side load.
