Osg 8692460 Carbide Jobber Drill Bit 4.6mm Egias

Product Description

The OSG 8692460 is a solid carbide jobber length drill bit designed for precision drilling in demanding production and maintenance machining environments. Built with a 140-degree split point and X-thinned web geometry, it reduces thrust force at entry and improves centering without a pilot hole. The EgiAs coating provides enhanced lubricity and wear resistance, extending tool life in hard and abrasive materials. At 4.6 mm in diameter with a 95 mm overall length and a 42 mm flute length, this bit delivers a 5xD reach suitable for through-hole and moderately deep drilling applications. Coolant-through capability supports high-speed runs in CNC and automated machining setups.

This drill bit is suited for use in CNC machining centers, drill presses, and manual machines where consistent hole quality and tight tolerances are required. It is typically applied in metalworking trades including tool and die, aerospace component fabrication, automotive, and general precision machining. The right-hand spiral flute design evacuates chips efficiently in ferrous and non-ferrous metals, stainless steels, and hardened alloys. The straight-cylindrical shank with a 5 mm shank diameter seats securely in standard drill chucks and collets.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 140-degree point angle with X-thinned web reduces walking and entry thrust
• EgiAs coating improves lubricity and extends tool life in abrasive applications
• Coolant-through design supports high-speed CNC drilling and chip evacuation
• 5xD flute-to-diameter ratio for moderately deep hole capability
• Right-hand spiral flute with 2-flute configuration for efficient chip removal

Compatibility

Designed as a jobber length replacement drill bit for standard drill chucks and collets accepting a 5 mm straight-cylindrical shank, within the 4.00 mm to 5.00 mm drill bit size range.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight-cylindrical shank fully and evenly in the collet or chuck to the recommended grip depth before tightening. When using coolant-through capability, verify that coolant supply lines are connected and flow is confirmed before initiating a cut.
