Osg 8699000 Extra Length Drill Bit 10mm Solid Carbide

Product Description

The OSG 8699000 is a solid carbide extra length drill bit designed for precision hole-making in demanding machining applications. Built to Series 6535 specifications, it measures 10.00 mm (0.3937 inches) in diameter with a 240 mm overall length and a 180 mm flute length, giving it a 15xD flute-to-diameter ratio suited for deep-hole drilling. The 140-degree split point reduces thrust and improves centering on entry. The EgiAs finish enhances wear resistance and heat management. Coolant-through capability delivers coolant directly to the cutting edge, making this bit effective in high-speed, high-heat environments. Licensed machinists and tool-and-die professionals are the primary users.

This extra length drill bit is intended for applications requiring extended reach beyond what standard-length bits provide. The 15xD flute length ratio makes it well suited for deep-bore work in steel, stainless, and other ferrous materials where chip evacuation and coolant delivery are critical. The X-thinned web geometry reduces cutting resistance and supports consistent chip flow through the full depth of cut. Right-hand cutting direction is standard for conventional CNC and manual drilling operations.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• EgiAs coating for thermal and abrasion resistance
• 140-degree drill point angle for reduced thrust and accurate entry
• Coolant-through design delivers fluid directly to the cutting zone
• X-thinned web geometry reduces cutting force and improves chip evacuation
• 15xD flute-to-diameter ratio enables deep-hole drilling in a single pass

Compatibility

Designed as a direct-fit replacement or upgrade for OSG Series 6535 solid carbide extra length drill bits used in standard straight-shank tool holders and collet chucks accepting 10.00 mm shank diameters.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians. Ensure the tool holder or collet chuck is rated for the 10.00 mm shank diameter and that runout is within acceptable tolerances before beginning a cut. Confirm coolant-through supply lines are connected and flow-tested prior to operation. Shut down the spindle completely before inserting or removing the bit from the holder.
