Osg 8696450 Taper Length Drill Bit 0.1772 in Solid Carbide

Product Description

The OSG 8696450 is a taper length drill bit engineered for precision drilling in demanding applications. Built from solid carbide, it delivers the hardness and heat resistance required for drilling tough materials where high-speed steel bits fall short. The bit features a 140-degree split point angle that reduces walking and improves hole entry accuracy. At 0.1772 inches (wire gauge #16) in diameter, it handles small-diameter bores with tight tolerances. Coolant-through capability supports high-feed drilling operations by flushing chips and managing heat at the cutting zone. Right-hand spiral flutes efficiently clear material. This bit is used by machinists, tool and die makers, and precision fabricators on CNC and manual drilling equipment.

The 8696450 suits applications requiring an extended reach beyond standard jobber length, making it appropriate for deep-hole work and setups where clearance demands a longer flute. The 8xD flute-to-diameter ratio provides the reach needed for deep bores while the solid carbide construction maintains rigidity to resist deflection. The EgiAs finish supports tool life in a range of workpiece materials. The straight shank with a 5.00 mm shank diameter fits standard drill chucks and collet holders commonly used on machining centers and drill presses. Web thinning (X-Thinned) reduces thrust requirements at the point, which is particularly useful when drilling harder alloys or stainless steels.

Key Features

• Solid carbide construction for hardness, heat resistance, and extended tool life
• 140-degree split point angle reduces center walking and improves entry accuracy
• Coolant-through design flushes chips and manages heat in deep-hole drilling
• 8xD flute-to-diameter ratio provides extended reach for taper length applications
• X-Thinned web reduces thrust force at the cutting point
• EgiAs coating supports tool durability across a range of workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-use taper length drill bit for CNC machining centers, drill presses, and manual machines equipped with standard drill chucks or collet holders accepting a straight shank with a 5.00 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool setup and machine operation. Secure the straight shank firmly in a compatible chuck or collet before operation and verify runout is within acceptable limits for the application. Engage coolant-through capability when available to maximize tool life and chip evacuation. Do not exceed the machine spindle speed and feed rate recommended for the workpiece material and drill diameter.
