Hertel C.E10.0476 Extra Length Drill Bit 3/16 in Hss

Product Description

The HERTEL C.E10.0476 is an extra length high-speed steel drill bit designed for drilling applications that require extended reach beyond standard drill bit lengths. Built from high-speed steel with an oxide finish, this bit features a 3/16 inch diameter, a 118-degree split point angle, and a 12-inch overall length with a 9-inch flute length. The two-flute geometry promotes chip evacuation during through-hole drilling. It is suited for use in general-purpose metal, wood, and plastic drilling applications where depth or reach is the primary constraint.

This drill bit is appropriate for use in machine shops, fabrication environments, and maintenance applications where deep or extended-reach holes are required. The 9-inch flute length provides clearance for chip removal during deep drilling passes. Electricians, HVAC technicians, plumbers, and general tradespeople commonly use extra length bits when drilling through structural members, wall assemblies, or equipment panels where a standard-length bit cannot reach.

Key Features

• 3/16 inch diameter with 0.1875 inch decimal equivalent for precision fitment
• 12-inch overall length and 9-inch flute length for extended-reach drilling
• 118-degree point angle for general-purpose entry on metal, wood, and plastic
• High-speed steel construction for durability across a wide range of materials
• Oxide finish provides basic corrosion resistance and reduces friction during drilling
• Two-flute design promotes chip clearance during deep drilling passes

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks and drill presses that accept 3/16 inch round shank tooling.

Installation Notes

Secure the bit firmly in the chuck before operation and verify runout is minimal before beginning a drilling pass. Use appropriate cutting fluid or lubrication when drilling metal to extend bit life and maintain point geometry. Reduce feed rate as the bit exits the workpiece to prevent grabbing or deflection. Wear appropriate eye protection and secure the workpiece before drilling.
