Hertel C.E10.1826 Extra Length Drill Bit 0.7188 in Hss

Product Description

The HERTEL C.E10.1826 is an extra length high-speed steel drill bit designed for deep-hole drilling applications that standard-length bits cannot reach. It features a 118-degree point angle for general-purpose entry on a wide range of materials, including mild steel, aluminum, wood, and plastics. The bit measures 0.7188 inches in diameter with a 9-inch flute length and a 12-inch overall length, giving machinists and fabricators the reach needed for through-holes in thick stock, structural members, or stacked workpieces. An oxide finish reduces friction and provides light corrosion resistance during use.

This drill bit is suited for use in stationary drill presses, milling machines, and heavy-duty handheld drilling equipment where extra reach is required. It is a general-purpose tool appropriate for metalworking shops, fabrication facilities, and maintenance operations that require drilling through deep sections. The 2-flute design provides efficient chip evacuation during extended cuts, which is critical for hole quality and tool life when working at full depth.

Key Features

• 0.7188-inch diameter for precise, consistent hole sizing
• 12-inch overall length and 9-inch flute length for deep-hole access
• 118-degree point angle suitable for general-purpose material entry
• High-speed steel construction for durability across common workpiece materials
• Oxide finish reduces friction and provides light surface protection
• 2-flute geometry promotes chip clearing during deep cuts

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks and collets accepting a 0.7188-inch shank diameter on drill presses, milling machines, and heavy-duty handheld drills.

Installation Notes

This bit should be installed by a qualified machinist or trained tradesperson familiar with rotary cutting tools. Secure the bit firmly in the chuck or collet and verify runout before drilling. Use appropriate cutting fluid or coolant when drilling metal to extend tool life and maintain hole quality. Always wear eye protection and ensure the workpiece is clamped securely before operation.
