Osg 8694280 Taper Length Drill Bit 0.1102 in Solid Carbide

Product Description

The OSG 8694280 is a solid carbide taper length drill bit designed for precision drilling in demanding industrial and metalworking applications. The bit measures 0.1102 inches (2.80 mm) in diameter with a straight shank diameter of 3.00 mm and an overall length of 80.00 mm. Its 140-degree split point geometry reduces walking and enables clean entry without a center punch. The EgiAs coating provides enhanced wear resistance and heat dissipation during high-speed drilling operations. This bit is installed and used by machinists, tool and die technicians, and precision fabrication professionals working in production environments.

This taper length drill bit is suited for deep-hole drilling applications where a standard length bit does not provide sufficient reach. The 8xD flute-length-to-diameter ratio and spiral flute design promote efficient chip evacuation during extended cuts. Coolant-through capability makes it compatible with CNC machining centers and other coolant-fed spindle setups. It is appropriate for drilling ferrous and non-ferrous materials in tight-tolerance production scenarios where tool rigidity and consistent hole quality are required.

Key Features

• Solid carbide construction for rigidity and wear life in hard materials
• 140-degree point angle reduces thrust and minimizes drill walk on entry
• EgiAs coating enhances surface hardness and thermal resistance
• Coolant-through design supports high-feed CNC and wet-drilling operations
• 8xD flute length enables deep-hole drilling with efficient chip clearance
• X-Thinned web geometry reduces cutting resistance and improves tool life

Compatibility

Designed as an OEM-style replacement taper length drill bit for use in CNC machining centers and manual drill presses equipped with compatible straight-shank toolholders accepting a 3.00 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with proper chuck or collet torque procedures. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify collet or chuck bore compatibility with the 3.00 mm straight shank before seating the bit. When operating with coolant-through capability, confirm that the machine spindle and toolholder are rated for through-coolant delivery before enabling coolant flow.
