Hertel C.E08.0714 Extra Length Drill Bit 0.2812 in Hss

Product Description

The HERTEL C.E08.0714 is an extra length high-speed steel drill bit designed for drilling applications that require greater reach than a standard jobber-length bit provides. It measures 0.2812 inches in diameter with an overall length of 8 inches and a flute length of 5.5 inches. The 118-degree drill point angle suits general-purpose drilling in a wide range of materials including mild steel, aluminum, and plastics. The oxide finish provides a degree of lubricity and corrosion resistance during cutting operations. Machinists, maintenance technicians, and fabricators use this bit when access depth or clearance constraints demand a longer shank-to-tip reach.

This bit is suited for general-purpose drilling in machine shop, maintenance, and fabrication environments. Its extra length makes it appropriate for through-hole drilling in thick stock, deep cavity work, or applications where a standard-length bit cannot reach the work surface. The two-flute geometry supports efficient chip evacuation in both ferrous and non-ferrous materials. It is compatible with drill presses, milling machines, and hand-held power drills equipped with a standard chuck capable of accepting a 0.2812-inch shank.

Key Features

• 0.2812-inch diameter for precise sizing in general-purpose drilling tasks
• 118-degree drill point angle for broad material compatibility
• 8-inch overall length provides extended reach beyond standard jobber bits
• 5.5-inch flute length supports deep-hole chip evacuation
• High-speed steel construction maintains edge integrity at elevated cutting temperatures
• Oxide finish reduces friction and provides light corrosion resistance

Compatibility

Designed as a general-purpose extra length drill bit compatible with any standard drill chuck or collet system accepting a 0.2812-inch shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Secure the bit firmly in the chuck or collet before operation and verify runout is within acceptable limits for the application. Always operate at a feed rate and spindle speed appropriate for the workpiece material and bit diameter. Wear appropriate eye protection and ensure the workpiece is clamped securely before drilling.
