Osg 8706800 Extra Length Carbide Drill Bit 0.315 in

Product Description

The OSG 8706800 is a solid carbide extra length drill bit designed for high-performance drilling in demanding industrial and machining applications. Built on the Series 6540 platform, it features a 140-degree split point with X-Thinned web geometry for reduced thrust and improved chip evacuation at entry. The EgiAs coating provides enhanced wear resistance and thermal stability during extended cutting cycles. At 0.315 inches (8.00 mm) in diameter with a 15xD flute-to-diameter ratio, this bit handles deep-hole drilling operations where standard-length tooling cannot reach. Licensed machinists, tool and die makers, and CNC operators are the typical end users.

This drill bit is suited for deep-hole drilling operations in production machining environments, including aerospace, mold and die, and precision metalworking applications. The coolant-through design delivers cutting fluid directly to the tip, making it well-matched to CNC machining centers equipped with through-spindle coolant. The straight-cylindrical shank accommodates standard ER collet chucks and hydraulic toolholders without adapters.

Key Features

• Solid carbide construction for rigidity and tool life in hard and abrasive materials
• EgiAs coating for improved wear resistance and reduced built-up edge
• 140-degree drill point angle for reduced thrust and self-centering entry
• X-Thinned web for improved chip flow and lower cutting forces
• Coolant-through design supports through-spindle coolant delivery for deep-hole applications
• 15xD flute length enables deep-hole drilling beyond standard drill reach

Compatibility

Designed as an OEM-style extra length drill bit for use in CNC machining centers and drill presses accepting an 8.00 mm straight-cylindrical shank with standard ER collet or hydraulic toolholding systems.

Installation Notes

Installation and operation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Secure the straight-cylindrical shank firmly in a properly sized collet or chuck to the toolholder manufacturer's specified clamping procedure. Verify through-spindle coolant pressure and flow rate meet the requirements of the application before initiating the cut.
