Hertel C.E14.1429 Cobalt Drill Bit 9/16 in 12 in Oal

Product Description

The HERTEL C.E14.1429 is a cobalt extra-length drill bit designed for demanding metal-drilling applications where standard-length bits fall short. Built from high-speed cobalt steel with a bright/uncoated finish, this bit features a 135-degree split-point tip that reduces walking and allows drilling to start without a center punch. With a 9-inch flute length and a 12-inch overall length, it gives machinists and fabricators the reach needed for deep-hole work in thick stock, structural components, or hard-to-access locations. The 2-flute geometry promotes efficient chip evacuation throughout the cut.

This extra-length bit is suited for general-purpose drilling in steel, stainless steel, cast iron, and other hard ferrous materials. It is a common choice for toolroom work, production machining, and fabrication shops where standard jobber bits lack the reach. Ideal for use in drill presses, CNC machining centers, and hand-held magnetic drills where the 9/16-inch diameter and extended length are required. This is a dry-running bit with no coolant-through capability, making setup straightforward for general shop use.

Key Features

• Cobalt tool material for improved heat and wear resistance in hard-material drilling
• 135-degree split-point tip reduces thrust force and eliminates the need for center punching
• 9-inch flute length enables deep-hole drilling in thick or stacked material
• 12-inch overall length provides extended reach for confined or deep workpieces
• 2-flute design promotes chip clearing throughout full flute depth
• Bright/uncoated finish suitable for general-purpose ferrous metal applications

Compatibility

Designed as a general-purpose extra-length drill bit compatible with standard drill chucks and collet systems accepting a 9/16-inch shank in drill presses, CNC machining centers, and magnetic drill units.

Installation Notes

This bit should be installed by a qualified machinist or tooling technician using a properly rated chuck or collet. Ensure the machine is powered down and the spindle is fully stopped before changing tooling. Secure the bit to the full recommended chuck depth to prevent slippage under load. For cobalt bits used in hard materials, apply appropriate cutting fluid where allowed by the application to extend tool life.
