Seco 03046183 Solid Carbide Jobber Drill 7.00 Mm Tialn

Product Description

The SECO 03046183 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding materials. Featuring a 140-degree split point and a TiAlN (titanium aluminum nitride) coating, this bit cuts efficiently through steel, stainless steel, cast iron, and other hard materials with reduced heat buildup and extended tool life. The straight-cylindrical shank measures 8.00 mm in diameter and seats securely in standard drill chucks and toolholding systems. With an overall length of 91.00 mm (3.585 inches) and a two-flute spiral design, it delivers clean chip evacuation in through-hole and blind-hole applications. Part of the SD205A series, this drill is built to ANSI standards.

This drill bit is suited for machining operations in industrial, toolroom, and production environments where tight tolerances and consistent hole quality are required. The 7.00 mm cutting diameter and 53.00 mm flute length support a maximum drilling depth of 43.00 mm, making it appropriate for moderate-depth holes in ferrous and hard material workpieces. It is compatible with CNC machining centers, drill presses, and manual machines equipped with appropriate toolholding. Machinists, tool-and-die makers, and production operators working with steel and stainless steel applications will find this drill appropriate for general drilling tasks where high-performance carbide tooling is specified.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiAlN coating reduces friction and heat, extending tool life in steel and stainless steel
• 140-degree point angle improves self-centering and reduces thrust force on entry
• Two-flute spiral design promotes efficient chip evacuation during drilling
• Straight-cylindrical shank (8.00 mm diameter) fits standard chucks and toolholders
• Built to ANSI standards as part of the SECO SD205A series

Compatibility

Designed for use in drilling applications involving primary workpiece material codes P (steel), M (stainless steel), K (cast iron), and H (hard material). Drill bit size range covered by this series is 6.00 mm to 7.00 mm (0.2500 to 0.3000 decimal inch). No coolant-through capability; intended for external coolant or dry cutting setups.

Installation Notes

This drill bit is installed by machinists or CNC operators into compatible drill chucks or collet-style toolholders rated for the 8.00 mm shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout and chuck concentricity before beginning a drilling cycle, as excessive runout accelerates wear on carbide tooling. Follow the machine tool manufacturer guidelines and applicable shop safety codes when setting feeds and speeds for carbide drills in ferrous materials.
