Seco 02898313 Drill Bit 8.10mm Solid Carbide Tialn 140 Deg

Product Description

The SECO 02898313 is a screw machine length drill bit designed for high-performance drilling in metal, alloy, and other demanding workpiece materials. Built from solid carbide and coated with TiAlN (Titanium Aluminum Nitride), this bit delivers superior heat resistance and tool life compared to HSS equivalents. It features a 140-degree split point for self-centering entry with reduced thrust, a 8.10 mm cutting diameter, and an overall length of 89.00 mm (3.5039 inches). The straight-cylindrical shank at 10.00 mm diameter seats securely in standard drill chucks or collet holders. Machinists, toolroom technicians, and CNC operators specify this bit for precision hole-making in production environments.

This drill bit is suited for use in CNC machining centers, drill presses, and manual mills where screw machine length (stub-length) geometry is required for rigidity in short-reach applications. The coolant-through design supports internal coolant delivery, making it well-matched to high-speed metal cutting setups where chip evacuation and heat management are critical. Typical applications include drilling operations in steel, stainless steel, cast iron, and high-temp alloys at production tolerances.

Key Features

• Solid carbide construction for high rigidity and wear resistance in hard materials
• TiAlN coating provides elevated heat resistance and extended tool life in dry or high-speed cutting
• 140-degree standard point angle for fast self-centering penetration with reduced thrust force
• Coolant-through capability supports internal coolant delivery for chip flushing and heat control
• Straight-cylindrical shank at 10.00 mm fits standard chucks and collet toolholders
• 2-flute regular spiral geometry balances chip evacuation and cutting edge strength

Compatibility

Designed as a direct-fit replacement or standard-specification drill bit for use in CNC machining centers and drill press setups requiring a screw machine length solid carbide drill in the 8.00 mm to 9.50 mm diameter range with a straight shank.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with carbide cutting tool handling. Ensure the machine spindle and toolholder are fully stopped and de-energized before inserting or changing the drill bit. Carbide is brittle — avoid dropping or impacting the cutting edge during handling. Verify shank seating depth and runout before initiating a cut, and confirm that coolant-through passages are clear if internal coolant is used.
